Page 8 1.4.1 Ozone and Toxicity Ozone is found in gaseous form as a natural ingredient of the earth's atmosphere. Some of the chemical and physical properties of ozone are as follows: Terms Molecule Weight Boiling Point Melting Point Properties of Ozone (O3) 47.9982 g/g-mol -119  0.3 °C -192.7  0.2 °C Exposure to even low concentrations of ozone can be damaging to delicate nasal, bronchial and pulmonary membrane. Symptoms of acute ozone toxification appear at a concentration of about 1 ppm by volume. The type and severity of symptoms depend on the concentration and duration of exposure. In mild cases and in the early phases of severe cases, symptoms will include one or more of the following: • Irritation or burning of the eyes, nose or throat • Lassitude • Frontal headache • Sensation of sub-sternal pressure • Constriction or oppression • Acid taste in mouth • Anorexia In more severe cases, the symptoms may include dyspnoea, cough, choking sensation, tachycardia, vertigo, lowering of blood pressure, severe cramping, chest pain, and generalized body pain. Pulmonary oedema may develop with delayed onset, usually one or more hours after exposure. Following severe acute ozone toxification, recovery is slow. In the few severe human cases reported, 10 -14 days of hospitalization were required. In these cases, minimal residual symptoms were present for as long as 9 months, but all cases eventually recovered completely. The 1983 ACGIH has recommended a Threshold Limit Value (TLV) of 0.1 ppm (0.2 mg/m3) for ozone. The safe level for short human exposure to concentrations of ozone in excess of 0.1 ppm (Threshold Limit Value) is not known with certainty. The atmospheric concentration immediately hazardous to life is likewise not known, but inhalation of 50 ppm for 30 minutes would probably be fatal. The odor threshold of ozone for a normal person is 0.01 - 0.02 ppm by volume in air. 1.4.2 First Aid Treatment Move the victim to an uncontaminated atmosphere. Control restlessness and pain by the administration of sedatives and anodynes orally. Severe cases may require subcutaneous injections of small doses of meperidine hydrochloride (Demerol) for relief of pain. Give oxygen inhalation by facemask when the acute symptoms have subsided. Severe cases require hospitalization since deferred pulmonary oedema may develop. Page 9 1.5 General Safety Precautions Please pay attention to all caution, warning and danger statements at all times. Non-observance of the safety instructions can result in serious personal injury, death or damage to the equipment. Therefore observe the following: ▪ ▪ ▪ ▪ ▪ 1.5 Only engineers trained by the manufacturer should carry out maintenance on the BioTector.

Contact may result in electric shock and severe or fatal injury. DANGER During system installation, maintenance or servicing: • • • • • • Isolate the system power lines before starting any work in the electronic enclosure. All electrical work should be carried out by qualified electrical personnel only. Comply with all local and national regulations when working with electrical connections. Make sure the system is properly earthed (grounded) before switching on. It is required to connect the mains through an external isolator (2-pole disconnection switch), and if possible connect the mains through an earth leakage circuit breaker. When working with hot surfaces, use protective gloves and handle the components with care. 1.5.1 Précautions relatives à l’électricité et aux brûlures BioTector contient des composants électriques qui fonctionnent à des tensions élevées. Un contact peut engendrer un choc électrique et des blessures graves ou mortelles. DANGER À l’installation de l’appareil, sa maintenance ou son entretien: • • • • • • Isoler les fils électriques de l’appareil avant de commencer tout travail dans le boîtier électronique. Seul le personnel électricien qualifié est habilité à effectuer tous travaux d’électricité. Se conformer aux règlementations locales et nationales pour tout travail sur un branchement électrique. Avant de l’allumer, veiller à la bonne mise à la terre de l’appareil. Le branchement sur le courant secteur doit obligatoirement se faire par l'intermédiaire d'un interrupteur sectionneur externe (interrupteur bipolaire), et prévoyez si possible un disjoncteur différentiel. Utiliser des gants de protection pour les travaux sur les surfaces très chaudes et prendre soin en manipulant les composants. Page 11 1.5.2 Carrier Gas and Exhaust Gas Precautions BioTector uses oxygen (O2) gas as the carrier gas during its operation. The oxygen gas must be free of carbon dioxide (CO2) and nitrogen (N2) gases. The average rate of oxygen consumption in BioTector is 29 l/h (483 ml/min). Carbon dioxide filtered air, carbon dioxide and nitrogen contaminated oxygen gas are not suitable for BioTector TOC analyzer. When handling oxygen: • • • • • • • The same precautions, which are required for any high pressure or compressed gas system, must be taken to avoid accidents. Comply with all local and national regulations and/or manufacturer's recommendations and guidelines when working with oxygen. If oxygen cylinders are used, they must be transferred safely using appropriate equipment (e.g. carts, hand trucks etc.) If oxygen cylinders are used, they should be labeled clearly for identification and well secured for storage and transport. Avoid the use of extensive number of adaptors and couplers. Do not allow oxygen to come in direct contact with grease, oil, fat, and other combustible materials. If uncertain how to handle oxygen cylinders and high concentration oxygen, contact your local oxygen manufacturer. If oxygen concentrator is used, take precautions to avoid a fire in the area of the concentrator, install the concentrator only in a well ventilated area and comply with all local and national regulations. Vent waste gases to atmosphere or to a well ventilated area making the necessary connections on system exhaust. Under normal operating conditions, waste gases will contain oxygen, traces of carbon dioxide and the traces of volatiles/gases which may exist in the sample stream. Under abnormal conditions, the waste gases may contain traces of ozone. 1.5.2 Précautions relatives au gaz porteur et d'échappement Pour son fonctionnement, BioTector emploie de l’oxygène (O 2) comme gaz porteur. L’oxygène ne doit comporter aucun gaz carbonique (CO2) ni d’azote (N2). Le taux moyen de consommation d’oxygène du BioTector est de 29L/heure (483 ml/min). L’analyseur BioTector TOC ne tolère pas l’air filtré de gaz carbonique ni l'oxygène contaminé de gaz carbonique et d'azote. À la manipulation de l’oxygène: • • • • • • • Afin d’éviter les accidents, prendre les mêmes précautions que pour tout appareil à haute pression ou gaz comprimé. Pour toute opération avec de l’oxygène, se conformer aux règlementations locales et nationales et/ou aux recommandations et consignes du fabricant. S’ils sont employés, les cylindres d’oxygène doivent être transportés en toute sécurité à l’aide du matériel approprié (chariots, diables, etc.) S’ils sont employés, les cylindres d’oxygène doivent être clairement étiquetés pour en permettre l’identification et bien arrimés pour leur stockage et leur transport. Éviter d’utiliser un nombre élevé d’adaptateurs et de dispositifs de couplage. Ne pas laisser l’oxygène entrer en contact direct avec de la graisse, de l’huile, des matières grasses ou d’autres matières combustibles. Veuillez contacter votre fabricant local d’oxygène si vous avez des doutes sur la manière de manipuler les cylindres d’oxygène et l’oxygène de haute concentration. Dans le cas où un concentrateur est employé, prendre les précautions nécessaires pour éviter un incendie dans la zone du concentrateur, n’installer le concentrateur que dans un endroit bien ventilé et se conformer aux règlementations locales et nationales. Évacuer les gaz usés dans l’atmosphère ou dans un endroit bien ventilé en réalisant les branchements voulus sur l'échappement de l’appareil. Dans des conditions normales de fonctionnement, les gaz usés contiennent de l’oxygène, des traces de gaz carbonique et des traces de composants volatiles/gaz qui peuvent être présents dans l’échantillon. Dans des conditions anormales, les gaz usés peuvent contenir des traces d’ozone.

By pressing the ESCAPE key the user moves from the Analysis Data screen to the Analysis Graph screen. Pressing the ENTER key on the Analysis Graph screens brings the user back to the Analysis Data screen. Pressing ENTER key on the Analysis Data screen will bring up the Select Level screen, from where the user can select the desired menu level using the UP or DOWN and ENTER keys. Entry to each menu level can be controlled by numerical passwords. If the passwords are not set, pressing the enter key will bring the user directly to the sub menu screen of the selected level. If the system has been set up with passwords, the Password menu will appear and the password must be entered before access to the selected level is allowed. In all cases, pressing the ESCAPE key will return the user to the previous screen. 2.1.2 System Status Messages The system status messages are displayed on the top left hand side of the Analysis Data and Reagent Status screens. On most other screens, only the screen name is displayed in this location. System status messages are displayed in the following priority: 1. SYSTEM MAINTENANCE – the BioTector is in Maintenance mode, activated by the maintenance switch. 2. SYSTEM FAULT – There is a fault on the BioTector. System is stopped. 3. SYSTEM WARNING – There is a warning on the BioTector. System is running. 4. SYSTEM NOTE – There is a notification on the BioTector. System is running. 5. SYSTEM CALIBRATION – The BioTector is calibrating. This could be Span Calibration, Span Check, Zero Calibration or Zero Check. 6. System operation status. This could be one of either: ▪ SYSTEM RUNNING – system is running. ▪ SYSTEM STOPPED – system has been stopped by a fault or from the keypad. ▪ REMOTE STANDBY – system has been put into standby mode remotely. System has stopped analyzing. The BioTector time and date is displayed on the top right side of each screen. When a fault/warning/notification is logged in the system, a FAULT LOGGED message will alternate with the time/date in this location until the fault/warning/notification has been corrected. Changing most system settings are prevented when the BioTector is running.

These passwords are programmable, and if a password has been set up for a particular level in Password menu (see Section 8.3.14 Password for details), then it must be entered before the BioTector will grant access to the password-protected security domains. Use of a higher menu level password also allows access to lower levels/domains. Page 21 2.2 Operation Menu Operation Menu Diagram Operation menu allows the user to start and stop the analyzer. Menus related to system operation are also accessed using this menu. 2.2.1 Start Stop The user can Start or Stop the BioTector using the Start Stop menu. 1. Remote Standby. Remote Standby is an optional function, which is activated from Input 2 (by default) on the Power and Input/Output Board (e.g. from a flow switch). A “REMOTE STANDBY” message is displayed on the top left corner of the main Analysis Data screen to indicate that the BioTector is in remote standby state. When remote standby signal is activated, the BioTector stops analyzing. All menu access and operational functions remain as for BioTector normal running state. The BioTector runs one standby reaction every 24 hours, at the time programmed for the Pressure/Flow Test (at 08:15 AM by default). Sample is not taken during the remote standby reaction (only acid and base reagents are used). This reaction is tagged as “RS” (Remote Standby) in the system reaction archive. The 4-20mA signal or other output devices are not updated. When remote standby signal is deactivated, the BioTector starts analyzing. When remote standby signal is activated, the “Finish & Stop” or “Emergency Stop” must be selected before using such functions as Install New Reagents, Zero and Span Calibrations, Process Tests etc. If the BioTector is stopped using the “Finish & Stop” or “Emergency Stop” functions or automatically by a system fault, it will not be possible to start the BioTector by the removal of the remote standby signal. The “Start” function must be used to re-start the BioTector. When BioTector is started while the remote standby signal is activated, BioTector goes into remote standby state. The manual grab sample analysis can be carried out normally using the Manual Program menu when the BioTector is in remote standby state. Maintenance should only be carried out when “SYSTEM STOPPED” message is displayed on the top left corner of the main Analysis Data screen or when the system is powered down. When “REMOTE STANDBY” or “SYSTEM RUNNING” message is displayed on the screen, stop the BioTector using the “Finish & Stop” or “Emergency Stop” function. Caution Page 22 2. Start. This function starts the BioTector. When BioTector is started, the multi-stream operation sequence (if programmed) is reset. BioTector performs Ozone Purge, Pressure/Flow Test, Reactor Purge and Analyzer Purge sequences automatically before starting its analysis. • Ozone Purge sequence purges any residual ozone through the ozone destructor. • Pressure/Flow Test sequence confirm that there is no gas leak and there is no gas flow restriction in the BioTector. • Reactor Purge sequence purges any liquid from the reactor through the Reactor Valve. • Analyzer Purge sequence purges any CO2 gas from the CO2 Analyzer through the Exhaust Valve. An “*” is displayed to let the operator know the function has been activated. If there is a fault in the system, it will not be possible to start the analyzer until the fault has been rectified. 3. Finish & Stop. When this function is activated from the keyboard, the BioTector stops as soon as its present reaction is completed. An “*” is displayed to let the operator know the function has been activated. 4. Emergency Stop. When this function is activated the BioTector cancels the execution of the present reaction and quickly stops operation after the Ozone Purge, Reactor Purge and CO 2 Analyzer Purge sequences. An “*” is displayed to let the operator know the function has been activated. The Emergency Stop has highest priority, and always overrules the “Finish & Stop” function. Quick Startup Function: During maintenance, system testing etc. it may be necessary to quickly start and stop the BioTector to check various parameters. Pressing the ENTER key for the “Start”, when the RIGHT ARROW key is also pressed, bypasses the Pressure/Flow Test sequence, ensuring a quick startup. When the quick startup function is used, system will log a “28_NO PRESSURE TEST” warning in the fault archive and will start operation. The same warning will also be logged, when the BioTector is started from the Reagents Setup, Manual Program and Calibration menus using this function. Page 23 2.2.2 Reagents Setup This menu allows the user to access the Reagent menus. 1. Install New Reagents. Menu used to install and prime the reagents in the BioTector. Any “85_Reagents Low” and “20_No Reagents” warnings and notifications can also be reset in this menu. 2. Purge Reagents & Zero. Menu used to purge the reagents, and carryout a zero calibration cycle. 2.2.2.1 Install New Reagents I N S T A L L N E W C O N F I R M 1 < 2 3 4 7 1 0 1 2 N E R N E R N E T O S T R E A G E N T S 0 9 : 1 7 : 2 8 T H E F O L L O W I N G : W A C I D E S E T A C W B A S E E S E T B A W Z E R O C 2 0 0 m g A R T N E W C I C S W C O D O E A , R N N M N N M T E T I E A E O E O R C G C N C N T I T I ( 5 E N E T E T D 0 T D O D O I m R 1 2 - 0 9 - 0 2 3 5 0 m g / l M n S O 4 .

Span Calibration or Span Check cycles are part of the Install New reagents sequence if SPAN CALIBRATION or SPAN CHECK is activated in New Reagents Program menu. The basic Zero Check/Calibration and Span Check/Calibration parameters (operation ranges, number of reactions, standard solution concentrations etc.) are programmed in Zero Calibration and Span Calibration menus respectively (see Section 2.3 Calibration Menu for details). The comprehensive Zero Check/Calibration and Span Check/Calibration parameters are programmed in Zero Program and Span Program menus respectively (see Section 8.3.4.2 Zero Program and 8.3.4.3 Span Program for details). To run the Install New Reagents cycle, the BioTector must be stopped. Confirm that all or the corresponding new reagents have been installed on the BioTector, for instance for acid reagent, select New Acid Connected, and press the ENTER key. A tick mark will appear as confirmation that the new acid has been connected. Note that when one or more reagent volumes are updated in Reagents Monitor menu, system automatically resets the new reagents volumes in this menu and also updates the figures displayed in the main Reagents Status screen. All reagents volumes can be reset while system is running. This function allows the user to top up the reagents without stopping the system. However, when acid and/or base reagents are replaced or topped up, system requires a new Zero Calibration cycle. A “ZERO CALIBRATION REQUIRED” warning will be displayed on the screen when RESET ACID MONITOR and/or RESET BASE MONITOR are selected. Therefore, it is strongly recommended to stop the BioTector and activate the Start New Reagent Cycle or to run the Zero Calibration cycle using the Zero Calibration menu. If DI Water is used during the Zero Calibration/Check cycles (see ZERO WATER in section 8.3.4.2 Zero Program for details), and when “NEW ZERO WATER (DIW) CONNECTED” message is displayed in this menu, it is important that Zero Water (DI Water) is connected to BioTector’s Zero Water port or Manual/Calibration port (if these ports are not available, connect DI Water to Sample 1 port) before the Install New Reagent cycle is started. Failure to do so may have an impact on system zero response and the analysis results. Page 24 When all or the necessary reagents have been confirmed to be connected and reset in this menu, and when Start New Reagent Cycle is selected, the Install New Reagents cycle will be executed. It is the responsibility of the user to make sure that all reagent volumes are programmed correctly in Reagents Monitor menu, the reset of the reagents monitoring are carried out correctly in Install New Reagents menu and finally if necessary the Zero Calibration cycle is activated either with the Start New Reagent Cycle function in Install New Reagents menu or with the Run Zero Calibration function in Zero Calibration menu. The Install New Reagents cycle consists of the following steps: 1. Reagent Purge: System purges and fills all reagent lines with the new reagents. 2. Zero Calibration: The Zero Adjust (zero offset) level is set for all analysis ranges, and the Reaction Check level for TOC is updated (if the CO2 LEVEL is programmed as AUTO in Reaction Check menu). 3. If Span Calibration or Span Check is activated in New Reagents Program menu, a Span Calibration or Span Check is carried out. Once the procedure is completed the BioTector either stops or returns online, depending on the programmed setting of AUTOMATIC RE-START in New Reagents Program menu (see Section 8.2.5 New Reagents Program for details). 2.2.2.2 Purge Reagents & Zero The Purge Reagents & Zero function is an automatic procedure to purge the reagents, to set the zero offset and to set the reaction check levels in the BioTector. The program settings for the Reagent Purge are set up in the Reagents Purge menu. 1. Purge Reagents & Zero. This option allows the user to run the Purge Reagents & Zero cycle. 2.2.3 System Range Data Screen This menu displays the system specific, factory calibrated, analysis range data for all measured components (e.g. TIC, TOC, TC). BioTector can be calibrated with up to 3 analysis ranges for each measured component. When a specific component of a sample (e.g. TOC) is measured at a specific range (e.g. Range 2), the analysis of any other components (e.g. TIC etc.) of the sample are also carried out at the same analysis range.

This is achieved by one or a set of Manual Valves installed in the system. The manual analysis sequence can be started at the end of the current reaction, or at a time set by the user. When the manual sequence is complete, the system can be programmed to return online automatically. Note that all pressure/flow tests, zero or span cycles are interrupted by the manual operation mode. The Sample Pump reverse operation is also disabled during the manual operation mode by default, unless a Manual Bypass Valve is installed in the system and the REVERSE time is programmed for the corresponding Manual Valve in Sample Pump menu. All items in this menu can be modified when the BioTector is running unless: - No Manual Valves have been defined in the Output Devices menu. - The manual mode is currently running. - The manual mode is scheduled to start when the current reaction is completed. Note that the Manual mode always starts at the first programmed valve, and works its way down the programmed sequence. 1. Run After Next Reaction. To start the manual operation mode sequence after the next reaction the BioTector is currently running, press the ENTER key at this menu item. An “*” will indicate that this function has been selected. If the BioTector is stopped, then the Manual mode will start immediately. To deactivate this function before the manual operation mode has started, press the ENTER key again, or activate an alternative function. In systems built with the remote control of Manual Program option, the remote signal (Manual Mode Trigger from Input 7) activates the Run After Next Reaction function. 2. Run After 00:00. Similar to menu option 1 above, but the manual operation mode starts after the programmed time. 3. Return to On-line Sampling. This menu item allows the user to specify whether the BioTector should stop (with NO setting) or return to online monitoring (with YES setting) when the manual operation sequence is complete. 4. Reset Manual Program. Use this function to reset all the programmed settings to their default values. 6. - 30. Manual. In order to analyze one or a number of samples/standards using the manual operation mode, first connect the sample/standard to the manual port/s outside the BioTector. Then, select the corresponding Manual Valve in this menu (the first setting). Then, enter the number of samples (number of analysis reactions) to be taken through each Manual Valve (the second setting). Finally select the correct analysis range (RANGE 1, 2 or 3) if the concentration levels of the sample/standard are known. See System Range Data screen (see Section 2.2.3 System Range Data Screen for details) to view the available system ranges and to select the correct operation range. If the concentration levels of the samples/standards are not known, select AUTO so that BioTector can automatically select the optimum analysis range. When RANGE is programmed as AUTO, a minimum of five analysis reactions is recommended (the second setting) so that BioTector can find the optimum operation range with its automatic exceedance tracking function. When AUTO option is selected, depending on analysis range and system response, the first two or three analysis results may need to be discarded. Page 26 2.2.5 Reaction Archive Screen The Reaction Archive holds information on TIC, TOC, TC, VOC (in mgC/l), COD, BOD (in mgO/l), Drinking Water parameters (REMOVAL in %, and RESULT in FAIL/PASS condition), stream valve, reaction range, start time and related analysis information for the last 9999 reactions. If the archive is full, then every new reaction overwrites the oldest one in the archive. As the Reaction Archive contains 9999 events, the user must first enter the date at which the viewing of the archive starts. The Enter Date menu allows the user to specify the date of the first displayed reaction from the archive. Each reaction record in the reaction archive contains: - Start Time - reaction start time, which is displayed without seconds in this menu - Date - reaction date - Reaction Type - with the prefixes below: S1 to S3: M1 to M3: √ x RS: ZC: ZK: ZM: SC: SK: SM: A1 to A3: Reactions from stream 1 to stream 3. Reactions from manual sample stream 1 to manual stream 3. Sample sensor detected the sample or there is no significant quantity of air bubbles in the stream/manual grab sample lines. Sample sensor detected no sample or there is significant quantity of air bubbles in the stream/manual grab sample lines. See Sample Status in section 8.3.8 Fault Setup for details. Remote standby reaction. Zero calibration reaction. Zero check reaction. Manually input zero adjust. Span calibration reaction. Span check reaction. Manually input span adjust. 24 hours average result from stream 1 to stream 3. The user can navigate through the displayed reactions individually by pressing the UP and DOWN keys each time, or can navigate in steps of 10 reactions using the LEFT and RIGHT keys. Depending on system analysis type (e.g. VOC, TC –TIC etc.) and system display options (e.g. COD and/or BOD) settings, BioTector displays additional reaction data held on additional Reaction Archive screens. To access the screens, press the ENTER key, and to return to the previous screen, press the ESCAPE key. 2.2.6 Fault Archive Menu In the Fault Archive menu, the user can view the last 99 faults/warning/notification events logged in the system, confirm if these events are current or not, and acknowledge the current events. If the archive is full, then every new event overwrites the oldest one in the archive. The user can navigate through the displayed reactions individually by pressing the UP and DOWN keys each time, or can navigate in steps of 10 reactions using the LEFT and RIGHT keys. See Section 9 Troubleshooting of System Fault, Warning and Notification Events for a list of all systems fault, warning and notification events. The faults archive events are divided into three categories: - Fault: Faults are categorized as events, which stop BioTector operation. The 4-20mA signals are set to the fault level, and the fault relay is activated. The BioTector cannot be started unless the fault in the archive has been acknowledged. - Warning: Warning is a minor event, which does not require the BioTector to stop. The 4-20mA signals are not changed, only the fault relay is activated. - Notification: A notification is an information (e.g. “86_Power Up”, “87_Service Time Reset” etc.) displayed on the screen. To acknowledge any current events marked with an “*” in the archive, first identify and locate the faults/warnings/notification. Follow the necessary troubleshooting procedures to solve the problem. See Section 9 Troubleshooting of System Fault, Warning and Notification Events for details. Acknowledge the fault by pressing the ENTER key in the Fault Archive menu. Please note that there are system faults (e.g. 05_Pressure Test Fail), which cannot be acknowledged by the user. Such faults are reset and acknowledged automatically by the system when system is started, when system is rebooted or when the fault condition is solved. If an event cannot be acknowledged when the system is running, a “SYSTEM RUNNING” message is displayed on screen. Page 27 2.2.7 Time & Date Menu This menu allows the system time and date to be set by the user. To change the system time or date (hours, minutes, seconds, day, month and year), press the ENTER key, enter the new time and date and press the ENTER key again. In order to change the system date format, press the ENTER key, select new date format from the following day, month and year options: DD-MM-YY, MM-DD-YY, YY-MM-DD and press the ENTER key again. When the time is changed, it is possible for the BioTector to automatically start up if the new time is after the startup time for a scheduled task, for example the startup time for a manual sample sequence in Manual Program menu. 2.2.8 Contact Information Contact Information menu displays the manufacturer/distributor contact details. 2.2.9 LCD Adjust LCD Adjust menu allows the user to adjust the LCD screen’s contrast and backlight level. The default contrast and backlight setting is 50%. The adjustment is carried out by entering to the relevant setting and making the necessary change using the UP or DOWN arrow keys. When the UP/DOWN key is pressed and kept pressed, BioTector displays the relevant adjustment in real time. When the adjustment is completed, press the ENTER key to accept the new setting or press ESCAPE key to return back to the previous setting.

Zero Adjust. The Zero Adjust is used to compensate any organic contamination in the acid and base reagents and any absorbed CO2 in the base reagent. The Zero Adjust values are generated automatically by the system for each range when the zero calibration cycle is completed without any system warnings. Zero Calibration cycle is activated by selecting the RUN ZERO CALIBRATION function in this menu. When a Zero Check cycle is run using the RUN ZERO CHECK function, the system only checks the zero response at each range and displays the suggested Zero Adjust values in brackets “[ ]” for all ranges next to the current Zero Adjust settings. When a Zero Check cycle is completed, if necessary the suggested Zero Adjust values can be programmed manually by entering the corresponding suggested Zero Offset values for each range (1, 2 and 3) in this menu. When the Zero Adjust settings are entered manually, system logs this information in the reaction archive with the prefix “ZM” (Zero Manual). 4. Run Reagents Purge. The RUN REAGENTS PURGE function is used to prime all reagents in the BioTector. If necessary, the pump operation time for Reagent Purge cycle can be increased in the Reagents Purge menu. 5. Run Zero Calibration. Each time BioTector reagents are replaced or topped up and each time a service is carried out, it is strongly recommended to use the RUN ZERO CALIBRATION function so that the system can set the zero offset values automatically. The zero calibration reactions operate in the same manner as a normal reaction. Depending on system settings, BioTector either takes DI Water as a sample or does not take any sample during the Zero Calibration cycle. See ZERO WATER in section 8.3.4.2 Zero Program for details. To start the zero calibration, press the ENTER key at this menu item. An “*” will indicate that the function is running. At the end of the Zero Calibration cycle, the following settings are checked and updated: Page 29 1. The Zero Adjust settings for each range are updated automatically by the system using the uncalibrated TOC measurement (not the results seen on the LCD screen). If a Zero Check is used to check the zero offset, the suggested values are shown in brackets “[ ]” next to the actual Zero Adjust settings. 2. If the CO2 LEVEL is set as AUTO for automatic updating in the Reaction Check menu, then the reaction check CO2 Level is also updated automatically. 3. The CO2 Level is also checked against the BASE CO2 ALARM setting in Fault Setup menu. If the measured CO2 Level is greater that the BASE CO2 ALARM value, system generates a “52_HIGH CO2 IN BASE” warning. 6. Run Zero Check. Zero Check cycle is similar to the Zero Calibration above, but BioTector does not update any of the Zero Adjust or CO2 Level settings. System only checks the BASE CO2 ALARM described above. 8. Zero Program. Zero Program function allows the user to program the number of zero reactions run at one or more ranges (R1, R2 and/or R3). When the number of zero calibration reactions for one or two of the ranges is set to zero, system runs the zero cycle on the programmed range or ranges and calculates the Zero Adjust values for the other ranges automatically. It is recommended not to modify the factory set Zero Program values unless it is absolutely necessary. Any unnecessary modification in this setting may have an impact on the zero offset values. 9. Zero Average. Zero Average function allows the user to program the number of zero reactions to be averaged for each range (R1, R2 and/or R3) at the end of the zero cycles. It is recommended not to modify the factory set Zero Average values unless it is absolutely necessary. Any unnecessary modification in this setting may have an impact on the zero offset values. 11.  Zero Program.

Above menu displays the parameters for the TIC & TOC systems. In TC and VOC systems, the relevant parameters, identified below, are displayed in this menu. 1.-3. TOC Span Adjust. This menu item allows the user to set the TOC span adjust factors manually by entering the STANDARD solution used and the calibrated average reaction RESULT at each range (1, 2 and 3). When the STANDARD and RESULT values are entered, system automatically calculates the corresponding span factors of each parameter for each range.

This menu item allows the user to set the TIC span adjust factors manually for each range as described for TOC Span Adjust above. 10. Run Span Calibration. This function starts the Span Calibration cycle. The span calibration reactions are run at a single range programmed by the RANGE in this menu below. At the end of the span calibration cycle, BioTector automatically calculates the Span Adjust factors and displays it for Span Adjusts above. Unless it is manually modified, the same Span Adjust factor calculated for the programmed RANGE in this menu is used for the other two ranges as well. The span reactions operates in the same manner as a normal reaction, but the Sample Pump reverse operation is disabled to prevent the contamination of the standard solution connected to calibration/manual port. Span Calibration reactions have the prefix of “SC”. 11. Run Span Check. This function starts the Span Check cycle. The operation is similar to the Span Calibration cycle above, but BioTector does not update any Span Adjust values at the end of the span check cycle. Span Check reactions have the prefix “SK”. 13. Span Program. Span Program function allows the user to program the number of span reactions to be carried out during the Span Calibration and Span Check cycles. It is recommended not to modify the factory set Span Program value unless it is absolutely necessary. Any unnecessary modification in this setting may have an impact on the span adjust values. 14. Span Average. Span Average function allows the user to program the number of reactions to be averaged at the end of the Span Calibration and Span Check cycles. It is recommended not to modify the factory set Span Program value unless it is absolutely necessary. Any unnecessary modification in this setting may have an impact on the span adjust values. 15. Range. Range function allows the user to program the operation range at which the Span Calibration and Span Check reactions are carried out. If the selected range is in conflict with the programmed CALIBRATION STANDARD concentration in this menu, system automatically displays a “Caution! Reaction range or Standard is Incorrect” warning. See System Range Data screen (see Section 2.2.3 System Range Data Screen for details) in order to select the correct operation range or correct standard solution. 16. TOC Cal Std. TOC Calibration Standard function allows the user to program the concentration (mgC/l) of the TOC standard solution used in Span Calibration reactions. If the programmed concentration level is in conflict with the programmed RANGE above, system automatically displays a “Caution! Reaction Range or Standard is Incorrect” warning. See System Range Data screen in order to select the correct operation range or correct standard solution. If TOC Calibration Standard is programmed as 0.0mgC/l, system does not calculate or update any Span Adjust factors and therefore omits any span related warnings defined above. See Section 6.2 Calibration Standards for the details of BioTector standard solutions and preparation procedures. In TC systems, this parameter is named as TC Calibration Standard. 17. TOC Check Std. TOC Check Standard function allows the user to program the concentration (mgC/l) of the TOC standard solution used in Span Check reactions. If TOC Check Standard is programmed as 0.0mgC/l, any span related warnings are omitted. In TC systems, this parameter is named as TC Check Standard. 18. TIC Cal Std. TIC Calibration Standard function allows the user to program the concentration (mgC/l) of the TIC standard solution used in Span Calibration reactions. If TIC Calibration Standard is programmed as 0.0mgC/l, any span related warnings are omitted. In VOC and TC – TIC systems, it is recommended to run the TIC and TOC calibrations separately using separate standard solutions. 19. TIC Check Std. TIC Check Standard function allows the user to program the concentration (mgC/l) of the TIC standard solution used in Span Check reactions. If TIC Check Standard is programmed as 0.0mgC/l, any span related warnings are omitted. Page 32 20. TC Cal Std. In VOC systems, the sum of the TIC and TOC Calibration Standard solution is displayed as TC Calibration Standard. When TOC Calibration Standard is programmed as 0.0mgC/l, and when a concentration of TIC Calibration Standard is programmed above, BioTector displays the TC Calibration Standard as 0.0mgC/l on purpose. This allows the calibration of TIC without any effect on the TC calibration. See definitions for TOC Calibration Standard above, Section 8.3.4.3 Span Program and Section 6.2 Calibration Standards for further details. 21. TC Check Std. In VOC systems, the sum of the TIC and TOC Check Standard solution is displayed as TC Check Standard. When TOC Check Standard is programmed as 0.0mgC/l, and when a concentration of TIC Check Standard is programmed above, BioTector displays the TC Check Standard as 0.0mgC/l on purpose. This allows the check of TIC without any effect on the TC check. 23.  Span Program.

It is recommended to review these files to understand the system operation. The BioTector is designed to provide continuous online single-component (e.g. TOC) or multi-component (e.g. TOC & TN & TP) monitoring. The BioTector can operate with unfiltered samples including soft particulates up to 100 µm in diameter, and will give accurate measurements even when fats, high levels of salts and/or calcium is present in the sample. In BioTector multi-component analyzers, the system can be configured as a; 1) TIC & TOC system to measure the Total Inorganic Carbon (TIC) and Total Organic Carbon (TOC) content of a sample. The TOC result obtained from a TIC & TOC system represents the NonPurgeable Organic Carbon (NPOC). The TIC & TOC system is the standard system for samples which does not contain any volatile organic material or for samples which contains insignificant concentration of volatile organic material. 2) TC system to measure the Total Carbon (TC) content of a sample. The TC result obtained from a TC system represents the sum of TIC, NPOC and Purgeable Organic Carbon (POC) content. 3) VOC system to measure the TIC, TOC, TC and Volatile Organic Carbon (VOC) contents of a sample by means of two analysis reactions in single reactor configuration. VOC result represents the Purgeable Organic Carbon (POC). The TOC result in a VOC system is calculated from the TC and TIC measurements as TC – TIC. Therefore the TOC result includes the VOC (POC) content of the sample. In other words, the TOC result represents the sum of NPOC and POC content. TC, VOC and TC-TIC configurations are system optional features. As a brief introduction, the operation of BioTector analyzers can be summarized as follows: i. A sample liquid is brought to the analyzer by means of a peristaltic pump. The sample is injected into the BioTector reactor chamber. ii. A patented Two Stage Advanced Oxidation process (TSAO) oxidizes the organic material in the sample. iii. The carbon dioxide formed in the oxidation process is sparged and measured by a Non-dispersive Infrared (NDIR) analyzer. iv. The results are displayed as TIC, TOC, TC and VOC depending on system configuration. v. The oxidized liquid is discharged and collected in a sample catch-pot and again depending on system configuration, the Total Nitrogen and/or Total Phosphorus analysis is carried out applying direct photometric and/or colorimetric methods. vi. The sample tubes are purged by running the BioTector peristaltic sample pump in reverse direction. 4.2.1 BioTector Oxidation Method A patented Two Stage Advanced Oxidation process (TSAO), which uses hydroxyl radicals as the oxidizing agent, is used for the oxidation of the sample. The hydroxyl radical oxidation is a powerful oxidation technology, which keeps the wetted reactor parts clean in all types of applications. BioTector self-cleaning technology using hydroxyl radical oxidation ensures that the cleaning of the reactor is not necessary. Page 42 4.2.2 BioTector Sample Injection The BioTector analyzes a precise volume of liquid. The Sample Pump injects a pre-programmed number of pulses (half revolutions of pump) of liquid into the reactor for each measurement and therefore the volume of liquid included in each pulse is consistent. Sample is initially drawn from the source by a peristaltic Sample Pump. In standard TIC & TOC systems, Acid Pump activates and the first TIC acid is injected into the Mixer Reactor. Sample Valve and Reactor Valve activates, Sample Pump rotates forward and injects the sample directly into the Mixer Reactor with the relevant number of pulses appropriate to the range. In TC systems, the sample injection is carried out similar to the one described for TIC & TOC systems above but unlike TIC acid, first the base reagent (e.g. Sodium Hydroxide) is injected into Mixer Reactor. Sample Valve and Reactor Valve activates, Sample Pump rotates forward and injects the sample directly into the Mixer Reactor with the relevant number of pulses appropriate to the range. In VOC systems, BioTector carries out two separate sample injections for the two analysis reactions run consecutively in a single reactor configuration. The first analysis reaction is a TC reaction and the second one is a TIC & TOC reaction. The sample injection takes place as described for the TC systems and for the TIC & TOC systems above. Figure 4 shows the typical analysis layout of TIC & TOC system below. Detailed information on sample injection is available, in presentation and video formats, in the MMC/SD card shipped with the BioTector. It is recommended to review these files to understand BioTector sample injection. Page 43 Figure 4 BioTector analysis layout (typical TIC & TOC system) Page 44 4.2.3 BioTector Oxygen Concentrator The operation of BioTector oxygen concentrator is based on the crystalline zeolite molecular sieves, which permits the separation of oxygen gas from the mixture of gases that comprise air. As air flows through a column or bed of molecular sieve, the component gases it contains are adsorbed and stratified in the order of their relative affinity to the molecular sieve material. The process may continue until the next to last gas component stratifies near the end of the bed. Once the full bed length is used, the bed must be regenerated by desorbing (or purging) the adsorbed gases. Purging is accomplished by reducing the pressure in the bed and back-flushing with some of the concentrated gas product. Adsorption and desorption are completely reversible processes and are carried out indefinitely. The theory behind the operation of the oxygen concentrator is Pressure Swing Adsorption (PSA). This is based on flowing air through the column (the sieve bed) packed with molecular sieve material. The components of the air (Water Vapor, Carbon Dioxide, Carbon Monoxide, Hydrocarbons, Nitrogen, Oxygen and Argon) are adsorbed in order of their relative affinity to the molecular sieve material. Figure 5 shows the adsorption of air components inside the molecular sieves. Figure 5 Adsorption of air components in oxygen concentrator molecular sieves. Once the sieve bed is used, then it is re-generated by purging the adsorbed gasses from the molecular sieve. This is achieved by removing the air supply from the inlet to the sieve bed, and back-flushing the sieve bed with some of the concentrated gas product. The typical oxygen purity obtained from a PSA oxygen concentrator is 93% (±3%) with balance gas Argon. Figure 6 below shows the layout of BioTector oxygen concentrator and the operation of the Rotary Valve used for the PSA process. Page 45 Figure 6 BioTector oxygen concentrator layout Page 46 4.2.4 BioTector Analysis Types BioTector TOC analyzer has four factory calibrated analysis types: 1. TIC & TOC (NPOC) Analysis: Total Inorganic Carbon & Total Organic Carbon (Non-Purgeable Organic Carbon) Analysis 2. TC Analysis: Total Carbon Analysis 3. VOC (POC) Analysis: Volatile (Purgeable) Organic Carbon Analysis 4.2.4.1 TIC & TOC Analysis 1. An acid reagent (e.g. Sulfuric Acid) is added and the oxygen carrier gas flow is activated to remove the inorganic carbon. 2. An unfiltered sample is injected into the BioTector reaction chamber (Mixer Reactor). 3. The carbon dioxide gas is sparged by the addition of the acid reagent and is carried by the oxygen carrier gas and measured with a nondispersive infrared (NDIR) CO2 analyzer. The result is displayed as Total Inorganic Carbon (TIC). This reaction phase is called TIC phase. 4. Ozone generator is activated. A base reagent (e.g. Sodium Hydroxide) is injected and the sample is then oxidized with hydroxyl radicals, a strong oxidizing agent, which is generated by exposing high pH reagents to ozone. This reaction phase is called Base Oxidation phase. The complete oxidation of organic compounds takes place and carbonates are formed. 5. After the Base Oxidation phase, the carbonates are sparged in the form of carbon dioxide gas by the addition of an acid reagent. The carbon dioxide gas is carried by the oxygen carrier gas and measured with the NDIR CO2 analyzer. The result is displayed as Total Organic Carbon (TOC). This reaction phase is called TOC phase. The TOC result obtained from the TIC & TOC analysis type represents the Non-Purgeable Organic Carbon (NPOC). 6. At the end of the reaction, the oxidized sample liquid is discharged from the reactor with increased oxygen flow. 4.2.4.2 TC Analysis 1. The oxygen carrier gas flow and the ozone generator are activated. Base reagent is injected into the reactor and hydroxyl radicals are generated by exposing the base reagent to ozone. This reaction phase is called Pre-Oxidation. 2. An unfiltered sample is injected into the reactor of the BioTector with a low flow of oxygen carrier gas. 3. The volatile organic content of the sample is oxidized with hydroxyl radicals. This reaction phase is called VOC Oxidation, as the oxidation of the volatile organic matter is achieved without being sparged. 4. When the VOC Oxidation phase is complete, the oxygen gas flow and the ozone generator is activated and the remaining Non-Purgeable Organic Carbon (NPOC) content in the sample is oxidized by the hydroxyl radicals in Base Oxidation phase. The complete oxidation of organic and inorganic compounds takes place and carbonates are formed. 5. When the oxidation processes are completed, the carbonates are sparged in the form of carbon dioxide gas by the addition of an acid reagent. The carbon dioxide gas is carried by the oxygen carrier gas and measured with the NDIR CO2 analyzer. The result is displayed as Total Carbon (TC). The TC result obtained from the TC analysis type represents the sum of TIC, NPOC and Purgeable Organic Carbon (POC): TC = TIC + NPOC + POC 6. At the end of the reaction, the oxidized sample liquid is discharged from the reactor with increased oxygen flow. BioTector analysis types are optional features. If the BioTector is built as a TIC & TOC system only, modifications in the system configuration will be required for TC analysis to be possible. Page 47 4.2.4.3 VOC (POC) Analysis BioTector Volatile Organic Carbon (VOC) analysis type is a combination of TC analysis followed by a TIC & TOC (NPOC) analysis. The VOC result obtained from the VOC analysis type represents the Purgeable Organic Carbon (POC) content of the sample. When both TC and TIC & TOC analysis are complete, the flowing data is available: • • • • • • TC result, as measured and displayed from the TC analysis. TIC result, as measured and displayed from the TIC & TOC analysis. TOC result obtained from the TIC & TOC analysis represents the NPOC. TOC result including the VOC, which is calculated from the difference between the TC and TIC: TOCv = TC – TIC The TOC result displayed in VOC analysis type includes the purgeable organic carbon (POC) present in the sample. In other words the TOC result, obtained in VOC analysis type, is the sum of NPOC and POC: TOCv = NPOC + POC VOC (POC) result, which is calculated from the difference between the measured TC (from the TC analysis), and the sum of measured TIC and measured NPOC (from the TIC & TOC analysis): VOC (POC) = TC – (TIC + NPOC) The NPOC result, as measured from the TIC & TOC analysis, is not displayed, it is only used to calculate the VOC (POC) element in the sample. All displayed results can be programmed in the system and sent as 4-20mA output signals to an external device. In VOC analysis mode, it is possible to program BioTector to carry out scheduled TIC (TIC s) analysis and measure TOC, which includes NPOC and POC, for samples which may contain volatile organic carbon and the TIC concentration of the sample remains constant or changes slowly. With this measurement, the TIC value is measured on a scheduled basis depending on the TC CHECK concentration level programmed in Stream Program menu (see section 8.2.3 Stream Program for details). In VOC analysis mode with TICs, TOC result including the volatiles is calculated from the difference between the TC and TICs: TOCv = TC – TICs Scheduled TIC (TICs) measurement is unique to BioTector and is developed for applications such as condensate return monitoring in the petrochemical sector where rapid response is required in the event of a breakthrough of a volatile material. The traditional approach is to measure TC only, however this can result in inaccurate process decisions as TIC can often be present in the samples. In other words, any high TC response due to an increase in TIC levels may create unnecessary alarms. Additionally, the TIC result is a valuable measurement in its own right as it may highlight other specific or undesirable conditions within the sample such as the condensate return. BioTector analysis types are optional features. If the BioTector is built as a TIC & TOC system only, modifications in the system configuration will be required for VOC analysis to be possible. BioTectors built with the VOC analysis option can be programmed on site to operate with the TIC & TOC only or TC only analysis types.

If the ambient temperature exceeds 45°C, a vortex cooler can be installed to reduce the internal temperature of the BioTector. The BioTector should be installed vertically, with the maximum variation on each axis less than 2°. Ensure that there is enough clearance at the front of the BioTector to allow the door to be opened. Ensure that there is enough clearance at the left hand side of the BioTector for the tube and electrical connections. There should be enough clearance at both sides for the cooling fan to operate unimpeded. If there are corrosive gasses in the area, then the BioTector fan should be blanked off, and an instrument air purge system should be fitted. Caution Page 50 5.2.1 Analyzer Dimensions and Mounting The BioTector TOC analyzer enclosure is a Fiberglass Reinforced Polyester (FRP) cabinet. This enclosure facilitates easy access to all components and thus eases the service and maintenance procedures. Figure 7 and table 4 below gives the dimensions of various BioTector enclosures. Figure 7 BioTector Dimensions Table 4 BioTector Dimensions BioTector TOC Analyzer BioTector TOC Analyzer with extended enclosure Dimension A 750mm Dimension B 480mm Width 500mm Depth 320mm 1000mm 660mm 500mm 320mm Page 51 Figure 8 below illustrates the BioTector door clearance dimensions. Figure 8 BioTector Door Clearance Dimensions • • • • It is recommended that a clear space of at least 300mm is allowed around the analyzer from the right and the left sides and from the top and the bottom. The recommended clear space in the front of the analyzer is 1500mm for easy access to the system. When BioTector is being mounted on a wall or a stand, the support has to be strong enough to carry typically four times of the weight of BioTector (~180 kg). The BioTector should be lifted applying a safe method in accordance with local regulations. The minimum size of the bolts used to hold the BioTector in place should be M8.

Page 57 5.3 Air Supply and Reagent Connections The orientation of the ferrules inside each fitting of BioTector is critical for the correct operation of the system. Incorrect ferrule orientation may create gas/liquid leak and/or introduce air bubbles into the system lines. Therefore, the ferrules on all carrier gas, reagents, drain, exhaust and vent fittings have to be fitted with the correct orientation. Failure to do so will have an impact on the system operation and analysis responses. Figure 11 shows the fitting side and the nut side of SS-316 (stainless steel), PFA and PVDF fittings and their corresponding correct ferrule orientation. Figure 11 The correct ferrule orientation of SS-316, PFA and PVDF fittings on BioTector When tightening brand new stainless steel fittings, first fully insert the tube into the fitting, tighten the nut initially finger tight, then tighten a further 1¼ turns using an appropriate size spanner or an adjustable wrench. Stainless steel fittings used on 1/8” PFA tubing should be tightened only a further ¾ turns after finger tight. When re-tightening stainless steel fittings, which were already tightened during reassembly or after service, initially tighten the nut up to the point it was tightened previously, then tighten slightly more using an appropriate size spanner or an adjustable wrench. When tightening brand new PFA fittings, first fully insert the tube into the fitting, tighten the nut initially finger tight, then tighten a further ½ turn using an appropriate size spanner or an adjustable wrench. When retightening PFA fittings, which were already tightened during reassembly or after service, initially tighten the nut up to the point it was tightened previously, then tighten slightly more using an appropriate size spanner or an adjustable wrench. When tightening Swagelok PFA TEE fittings with blue nuts, first fully insert the tube into the fitting, tighten the nut initially finger tight, then tighten further using an appropriate size spanner or an adjustable wrench until the nut stops or until it is not possible to tighten the nut any further. These TEE fittings with blue nuts, used on the 1/8” PFA tubing, contain only one ferrule with no back cutting ring or no back ferrule. Acid and Base pump fittings, which also contain one CTFE ferrule, should be tightened fully finger tight, assuring a strong connection. Page 58 5.3.1 Air Supply Connection The recommended air quality for BioTector is -20°C dew point, free of water, oil and dust. A filter pack may be required to meet or exceed the air quality specification. BioTector Air Compressor can be supplied by BioTector distributors as an option. The air can be supplied to BioTector from: A) An existing instrument air supply line B) BioTector Air Compressor The required instrument air supply pressure is 1.5 bars. The minimum air supply flow rate is 8.4 m3/hour at 1.5 bar. The average air consumption is less than 5.4 m3/hour, and typically 3.6 m3/hour during online operation. Figure 12 below illustrates the two options for air supply: A) from BioTector Air Compressor, or B) from an existing instrument air supply line. Figure 12 BioTector air supply options Page 59 5.3.2 Reagent Connections Special precautions are needed when working with chemical reagents, both when renewing reagents and when dealing with leaks or spills. Some reagents can cause chemical burns and may cause injury or death if swallowed. Please refer to the symbols and codes on the reagent containers. DANGER Use of 20 or 25 liter containers is recommended for each BioTector reagents. Figure 13 below shows the correct setup and connection of BioTector reagents: Acid (6.0 N Sulfuric Acid containing 350 mg/l Manganese Sulphate Monohydrate) and Base (4.0 N Sodium Hydroxide). See Section 6 Reagents and Calibration Standards for further details. Figure 13 BioTector reagent setup and connections Page 60 As can be seen in the figure 13 above, base (Sodium Hydroxide) reagent container does not contain any vent (breathing) hole. The breathing air into the base container is supplied through the CO 2 filter, which must be fitted on the base container lid. Figure 14 below shows the detailed connections on BioTector base reagent. The purpose of the CO 2 filter is to prevent the base reagent coming in contact with atmospheric CO 2 present in the air. The soda lime inside the CO2 filter absorbs the atmospheric CO2 and prevents the base reagent getting contaminated. If any vent hole is accidentally drilled on the lid of the base container and if the fittings are not connected correctly on the base reagent, contamination will occur and the background CO2 readings will increase. Figure 14 BioTector Sodium Hydroxide reagent dip tube setup The vent port on the acid reagent dip tube should not be isolated or blocked. Failure to do so may cause the container to collapse and leak. The length of the dip tubes in all reagent containers should be adjusted correctly for the optimum usage of the reagents. If HCl acid is used, stainless steel (SS-316) weights/filters should not be used in the reagent. The recommended weights/filters for such reagents are PFA. Page 61 5.4 Sample, Drain and Exhaust Connections 5.4.1 Sample Inlet Tube Position For the fittings to remain leak proof, they must be kept clean and should not be over tightened. Over tightening of the fittings will damage them and cause eventual leakage. Caution BioTector operates on unfiltered samples, the setup of the sampling point is important for the correct operation of the system. BioTector can handle soft particulates up to 100µm in diameter, however hard particulates (e.g. sand) will damage the analyzer and should be removed from the sample. The sample tubing length between the sample intake point and the BioTector sample port should be 2.5 meters exactly. The height of the sample chamber should be between 100mm and 500mm below the BioTector. BioTector in fact can draw samples from distances greater than 2.5 meters however, such distances may have an impact on the Sample Pump tubing life and may require changes in system configuration settings for the correct operation of the system. The point where the sample is taken from should not be pressurized. The sample inlet and outlet should be at ambient pressure. The sample temperature should be between 2°C and 60°C (36°F - 140°F). The required minimum sample volume is 100ml per sample. The drain tube should be placed to a well ventilated area at ambient pressure and it should not be subjected to any back pressure. Figure 15 and 16 illustrate the correct positioning and setup of the BioTector sample tube in various/optional sampling systems. Figure 15 BioTector sample tube position in various sampling systems Page 62 Page 63 5.4.2 Drain and Exhaust Connections The BioTector should be installed in a well-ventilated area with the exhaust port piped to an external vent. The installation should be carried out in accordance with Section 1 Safety Precautions. WARNING All BioTector drain tubing must be positioned correctly so that any liquid pumped will drip freely into a larger drain chamber. The correct positioning and setup of the drain ports prevent liquid accumulation and measurement errors. All drain ports should be directed to a well ventilated area as oxygen and other gases may be released during the analysis. The drain tubes should be at atmospheric pressure and should not be subjected to any back pressure as this may result in measurement errors. The exhaust tube should be piped out to a well ventilated area as oxygen and other gases will be released during the analysis. The end of this tube should be positioned in a downward position so that water condensation and freezing will not occur during winter months. Figure 16 illustrates BioTector connections including the Sample, Manual grab sample, Sample Out (drain) and the Exhaust connections. Figure 16 BioTector drain and exhaust connections Page 64 Section 6 6.1 Reagents and Calibration Standards Reagents BioTector TOC analyzer uses the following reagents: I. Acid: 6.0 N Sulfuric Acid (H2SO4) Reagent containing 350 mg/l Manganese Sulfate Monohydrate II. Base: 4.0 N Sodium Hydroxide (NaOH) Reagent Reagents should not contain high levels of organics, nitrates and phosphates. Ideally, the level of organics, nitrates and phosphates should be less than 100 g/l (ppb) in the deionized water used to prepare TOC analyzer reagents. Acid and Base reagents are stable up to 1 year. The reagents must be stored in a safe and secure location, where the temperature does not drop below 2°C, in compliance with the local regulations. Table 6 below summarizes the total days each BioTector TOC Analyzer reagent lasts at various system configurations: Table 6 BioTector TOC Analyzer Reagent Consumption REAGENTS Acid Base Container Size (Liters) TOTAL DAYS REAGENT LASTS 19 19 239 239 Above table is derived from several online operation parameters such as 100% online time. Recommended bunds (reagent spill trays) to contain above quantity reagents are 1x 50 Liters. Page 65 6.2 Calibration Standards All hygroscopic chemicals in crystal form should be dried in an oven set at 105°C for 3 hours to remove any traces of absorbed water. All prepared solutions must be mixed thoroughly with a magnetic stirrer or inverted manually at least ten times or until all crystals are completely dissolved inside the solution. Caution The following compounds can be used to prepare calibration standard solutions in BioTector. To prepare a 1000mgC/l Total Organic Carbon (TOC) standard solution, use one of the following: • Potassium Hydrogen Phthalate, C8H5KO4, 2.13g (99.9% purity) in one liter of deionized water. Water solubility: 80 g/L at 20°C. • Acetic acid, C2H4O2, 2.51g (99.8% purity) in one liter of deionized water. Water solubility: Miscible in all proportions. • Glucose, C6H12O6, 2.53g (99% purity) in one liter of deionized water. Water solubility: 512g/L at 25°C. To prepare a 1000mgC/l Total Inorganic Carbon (TIC) standard solution, use one of the following: • Sodium Carbonate, CNa2O3, 8.84g (99.9% purity) in one liter of deionized water. • Sodium Hydrogen Carbonate, CHNaO3, 7.04g (99.5% purity) in one liter of deionized water. • Potassium Carbonate, CK2O3, 11.62g (99.0% purity) in one liter of deionized water. The quantity of concentrated chemical required to prepare stock calibration solutions will change with the % purity of the chemical used. If the purity of the chemical is different than the figures displayed above, the necessary quantity needs to be recalculated from the purity of the chemical. See example in the following page. Caution Depending on the system analysis ranges (see System Range Data menu), every BioTector requires specific calibration standard solutions. The required concentration of the calibration standard solutions can be identified in Span Calibration menu. Page 66 The calculation of the quantities required to prepare Potassium Hydrogen Phthalate (KHP) standard solutions with various purities are given as an example below: Name: Formula: Potassium Hydrogen Phthalate C8H5KO4 Carbon, 12 Oxygen, 16 Potassium, 39 Hydrogen, 1 Total weight x8 x4 x1 x5 = = = = = 96 64 39 5____________ 204.22 g/mol 47% of KHP is Carbon. Purity of the KHP is 99.9%. Therefore, to prepare a 1000 mgC/l standard solution, add 2.13g of KHP in a flask and add enough deionized water to make it exactly 1 liter solution. Note that the quantities required change with the % purity of the chemical used. Table 8 below gives the KHP quantities required at various % purity for the preparation of 1000mgC/l calibration standard. Table 8 Quantity of KHP required to prepare 1000 mgC/l standard at various purities. % Purity of KHP Quantity of KHP (grams) to prepare 1000 mgC/l Standard 100 2.127 99.9 2.129 99.5 2.138 99.0 2.149 95.0 2.239 90.0 2.364 To prepare standard solutions containing more than 1000 mgC/l, the required solvent can be mixed directly with deionized water. Table 9 below gives the required quantity of KHP for various concentration standard solutions to be mixed with deionized water and added enough deionized water to make the solution exactly 1 liter. Table 9 Quantity of KHP required to prepare various concentration TOC standard solutions. TOC Standard Solution Quantity of 99.9% KHP (grams) Concentration (mgC/l) to be added into 1 Liter DIW 1000 2.129 1250 2.661 1500 3.194 2000 4.258 5000 10.645 10000 21.290 Page 67 Preparation of Calibration Standard Solutions: Use eye protection and gloves. Standards solutions greater than 1000mg/l can be prepared directly without any dilution by simply mixing the necessary quantity solvent or salt with deionized water. Standard solutions below 1000mg/l concentration should be prepared by dilution technique. First a 1000mg/l standard stock solution should be prepared, and then the required lower concentration standard solution should be prepared by applying the necessary dilution procedures: ➢ For example, to prepare a 50mgC/l TOC only standard solution, first weigh 50 grams of the 1000mgC/l stock standard. Add 50 grams of the 1000mgC/l standard into a one-liter flask and add enough deionized water to make the solution exactly 1 liter. ➢ For increased accuracy, standard solutions below 5mg/l (ppm) concentration should be prepared with two or more steps dilution. For example, to prepare a 1mgC/l standard, first prepare a 100mgC/l standard by adding 100 grams of the 1000mgC/l standard into a one-liter flask and by adding enough deionized water to make it exactly a 1 liter solution. Then add 10 grams of the 100mgC/l standard into a one-liter flask and add enough deionized water to make it exactly 1 liter. ➢ Standard solutions at μg/l (ppb) levels should be prepared with several dilution steps. For instance, a 1mgC/l (1000 μg/l) standard should be prepared with two or more steps dilution as described above. To prepare a 50μg/l standard, add 50 grams of the 1000μg/l standard into a one-liter flask, and add enough deionized water to make it exactly 1 liter. Shelf Life and Storage of Calibration Standard Solutions: ❖ TOC standards prepared from Potassium Hydrogen Phthalate is typically stable for a month once it is kept in a closed glass container and refrigerated at 4°C. ❖ All other standards such as TOC prepared with Acetic Acid and TIC standards are recommended to be used within 48 hours of manufacture. Page 68 Section 7 Analyzer Commissioning and Startup The check list below must be used to ensure that the installation has been properly carried out. Please proceed through the check list in the given order, completing the 5 sections below. Detailed commissioning and startup procedures are available in a presentation format in the MMC/SD card shipped with the BioTector. It is recommended to review this document before starting the commissioning and startup procedures.

The average air consumption is less than 5.4 m3/hour, and typically 3.6 m 3/hour during online operation. When the oxygen concentrator is running, the pressure typically cycles from 1.5 bar to 0.9 bar. Option A: Instrument air. The set point pressure of the air, supplied from an existing instrument air supply line, should be 1.5 bar. The recommended air quality is -20°C dew point, free of water, oil and dust. Option B: BioTector Compressor. The set point air pressure supplied from BioTector compressor should be 1.2 bar. _____ Page 69 In BioTectors built with a vortex cooler, air should be supplied to the vortex cooler using a regulator, which is dedicated for the vortex cooler only. Connect the EXHAUST port with ¼” PFA tube to a safe and well ventilated area or to open atmosphere. The tube must have no restrictions and it must be placed so that any condensation and liquid buildup in the tubing is prevented. The maximum length of ¼” PFA tubing installed in Exhaust line is 10 meters. If tubing longer than 10 meters is required, the use of a larger ID tubing or pipe is recommended. The end of the exhaust tubing should have a slight downward slope and should be located in an environment so that any condensation or liquid at the outlet of the tubing cannot freeze during cold weather. See figure 16 in Section 5.4.2 Drain and Exhaust Connections for details. _____ Remove the tapes, which are used to seal the ends of the supplied CO 2 filter. Fit the CO2 filter to the Base container and seal the Base container tightly. See figure 13 and figure 14 in Section 5.3.2 Reagent Connections for details. _____ Connect the Acid (6.0 N Sulfuric Acid, H2SO4, containing 350 mg/l Manganese catalyst) and Base (4.0 N Sodium Hydroxide, NaOH) containers to the BioTector’s ACID and BASE ports with 1/8” PFA tube. ~20 liter reagents last more than 6 months. Confirm that weight fittings (which contain 70 micron filters) supplied are installed at the end of the acid and base reagent dip tubes. _____ Confirm the sample or samples are supplied to the analyzer from a sample chamber and are at ambient pressure. See examples in figures 15 and 16 in Section 5.4 Sample, Drain and Exhaust Connections for the correct positioning and setup of the BioTector sample tube in various sampling systems. Locate the sample chamber within 2.5 meters of the BioTector. The sample tubing length between the sample intake point and the BioTector SAMPLE port should be 2.5 meters exactly. The height of the sample chamber should be between 100mm and 500mm below the BioTector. _____ Referring to typical examples in figures 15 and 16 in Section 5.4 Sample, Drain and Exhaust Connections, connect the sample or samples to the BioTector with ¼” PFA tube. These ports are labeled as SAMPLE 1 and if installed SAMPLE 2 etc. _____ If a BioTector SAMPLER has been supplied with the system, connect the sampler in accordance with the drawings and instructions in the sampler user manual. _____ If a SIGMATAX SAMPLER has been supplied with the system, connect the sampler in accordance with the technical drawings and instructions in the BioTector and Sigmatax user manuals. Connect the sample tubing (using the 1/4 to 1/8 inches reducing union/connector fitting) and the Fiber Optic cable, coming from the Sigmatax Sampler, to the BioTector. _____ Connect the SAMPLE OUT port with ¼” PFA tube to well ventilated pressure free drain. The tubing length between the drain and the BioTector SAMPLE OUT port should be maximum 2 meters. The tube should be fitted so that it cannot freeze in cold weather. See figure 16 in Section 5.4.2 Drain and Exhaust Connections for details. _____ If fitted, connect ¼” PFA tube to the MANUAL or CALIBRATION ports. Remove all tapes placed around the fittings for shipment. The tubing length between the manual grab sample intake point or calibration standard solution and the BioTector MANUAL/CALIBRATION ports should be between 2 and 2.5 meters. The height of the manual grab sample or calibration solution should be between 100mm and 500mm below the BioTector. _____ If the BioTector is supplied as a “purge ready” system, connect the -20°C dew point, oil, water and dust free purge air to the ¼” Swagelok fitting located on the metal plate on the top left hand side of the BioTector enclosure. The purge air is instrument air which is typically at 60 L/min flow, and filtered with a 40 microns or smaller filter. The purge ready system is supplied with an air outlet port “vent” where the purge air is discharged. _____ 2. POWER UP: Power up the analyzer. Go to Operation, Time & Date menu and adjust the time and the date. Using the Simulate menu (see Section 8.1.2 _____ Simulate ), check the following: Confirm that the Exhaust and Reactor Valves are working. _____ Page 70 Confirm that the Sample Valve is working. _____ If installed, confirm that all other valves (e.g. multi-stream valve) are working. _____ Check the air supply pressure. The set point pressure should be 1.5 bar. When the oxygen concentrator is running, the pressure typically cycles from 1.5 bar to 0.9 bar. Check the O2 PRESSURE SENSOR in O2-Controller Status menu. The pressure should be between 390 mbar and 400 mbar at the idle 1 l/h “Mass Flow Controller” MFC FLOW. At 60 l/h MFC SETPOINT flow, the pressure should not be less than 320 mbar. See Section 8.1.6 Oxygen Controller Status for details. _____ Oxygen Purity Test: Power up the system for at least 10 minutes before the oxygen purity test is carried out. Using the Simulate menu (see Section 8.1.2 Simulate) set the MFC (see figure 2 and table 2 in Section 4.1.1 Analysis Enclosure) flow to 10 l/h and flow oxygen gas through the CO2 analyzer for 5 minutes. At the end of this period, the CO 2 analyzer zero reading (ppm CO2) should be within ±0.5% of full scale of the CO2 analyzer range. For instance, if the CO2 analyzer range is 10000ppm, then the CO2 analyzer zero reading should be typically within ±50ppm. Go to CO2 Analyzer menu (see section 8.3.10 CO2 Analyzer) to view the CO2 Analyzer Range. _____ (If the CO2 analyzer zero reading is outside the specifications, confirm that there is no CO 2 in the oxygen gas by connecting the CO2 filter “used with the sodium hydroxide reagent container” between the Cooler and CO2 analyzer inlet port and set the MFC to 10 l/h. As the size of the CO2 filter is small, keep the 10 l/h gas flow running for at least for 5 minutes and record the CO2 zero readings at the end of the 5 minute period. If the CO2 zero readings do not drop significantly with the CO2 filter in place, this will indicate that there is no CO2 contamination in the oxygen supply.) 3. PUMP TESTS: Caution! Below procedures involves handling strong acid and base reagents. Necessary safety precautions, such as wearing eye protection and gloves, should be taken throughout these tests. Go to Zero Calibration menu and select RUN REAGENTS PURGE function to prime the pumps. The factory Reagents Purge settings to prime reagents typically cover ~3 meters distance between the reagent containers and the BioTector. If it is necessary to increase the reagent purge times, see section 8.3.4.4Reagents Purge for details. __ (If the reagent lines do not fill during the Reagents Purge cycle, stop the BioTector to prime the pumps _____ __ manually.

Page 80 8.1.1.5 pH Test The user must understand the procedure for testing the pH in the BioTector. Use eye protection and gloves. Have all the relevant parts for this test ready (primarily beaker and pH paper) before carrying out the test. WARNING For the pH test to be accurate, the previous reaction should have finished normally, so that any liquid carried over from that reaction will not affect the pH test. Significant volume of liquid loss, during the pH test phases 1, 2, 3 or 4, may have an impact on the consecutive pH tests. In such cases, the test must be stopped at that specific phase, where the significant volume of liquid is lost, and re-started from pH Test Phase 1 below. When the pH test is re-started, the corresponding pH measurements can be skipped for the previous valid tests. General overview of the operation of the pH test: The description below is for the TIC & TOC mode. Phase 1: Prepare the test equipment, and start the test. Phase 2: The BioTector carries out a normal startup operation, including ozone purge, reactor purge, pressure test and flow test to ensure that the system is purged and leak tight. Phase 3: The TIC acid and sample are added into the reactor, mixed and then the program pauses, to allow the pH to be tested. Phase 4: The base is added to the solution in the reactor, and then the program pauses, to allow the pH to be tested. Phase 5: The TOC acid is added to the solution in the reactor, and then the program pauses, to allow the pH to be tested. Phase 6: The reactor and CO2 analyzer are purged. pH Test, Phase 1: P H 1 < 2 3 4 5 6 T E S T R M S T C S A O T A O T N D A K N O 0 9 : 1 7 : 2 8 G E , V A E R T T E E S A M T I N U E P T E S L V E S T P L E T O T 1 2 - 0 9 - 0 2 1 , S T R E A M T I C + T O C N E X T 1 P H A S E This menu enables the user to test the pH in the BioTector. 1.

In BioTector, when the user enters the Simulate menu, as the oxygen gas flow will be required, the oxygen generator starts to operate automatically. The menu also shows the current status of all devices when the BioTector is running. Note that the Simulate screen may change slightly depending on system settings. Any settings made by the user in this menu are automatically reset when the user exits this menu. The line below the time and date shows the MFC flow in l/h and actual CO 2 analyzer reading in ppm. Each time a component is activated, the BioTector will interlock additional devices to ensure that the component being tested can be checked in a manner that will not cause consequential damage to the overall system. It is recommended that each test is evaluated carefully, for although the interlocks are extensive, it may still be possible to damage the system. In simulate menus, most items require a minimum of 6 l/h oxygen flow set on the Mass Flow Controller (MFC) to operate. This is a system safety interlock, which is implemented to prevent the system from flooding. When ESCAPE key is used to return to the Diagnostics menu, BioTector carries out an automatic pump synchronization process. Page 85 1. MFC.

Page 95 8.1.5 Input/Output Status Input/Output Status menus are used for monitoring the analog and digital inputs and outputs for advanced diagnostics purposes. Digital Input The Digital Input menu allows the engineer to monitor the system digital inputs. This feature is useful for the system trouble-shooting or diagnostics. On the screen the digital inputs are organized in columns and rows with their code, logical states and function. Each input name is composed of the “DI” prefix and two-decimal index, which identifies the input. For example, the digital input named “DI06” is digital input 6, which is the ENTER key. Its logical state is shown as 0, therefore the ENTER key is not pressed or activated. When ENTER key is pressed, its logical state will be shown as 1. In the idle or open circuit state, all the system digital inputs are set to logical state 0. The active or closed circuit state is logical state 1. The programmable digital inputs are marked as [PROGRAMMABLE] in this menu. Digital Output The Digital Output menu allows the engineer to monitor the system digital outputs. This feature is useful for the system trouble-shooting or diagnostics. On the screen the digital outputs are organized in columns and rows with their code, logical states and function. Each output name is composed of the “DO” prefix and twodecimal index, which identifies the output. For instance, the digital output named “DO34” is digital output 34, which is used to control the heater of the Ozone Destructor. Its logical state is shown as 0 and 1, which stands for OFF and ON respectively. Upon system power up or reset, all system digital outputs are set to logical state 0. Analog Input The Analog Input menu allows the user to monitor the system analog inputs. This feature is useful for the system trouble-shooting or diagnostics. On the screen the analog inputs are organized in columns and rows. Each analog input has three parameters. The first is ADC converter digital value, the second is the input voltage measured in volts and the third is the function. The BioTector uses a 12-bit ADC, therefore the range of the digitized inputs are 0-4095. The voltage range is 0 to 5.00 Volts. Analog Output The Analog Output menu allows the user to monitor the system analog outputs. This feature is useful for the system trouble-shooting or diagnostics. On the screen, each analog output has three parameters. The first is DAC converter digital value, the second is output voltage measured in volts and the third is the function. The BioTector uses a 12-bit DAC, therefore the range of the digitized outputs are 0-4095. The voltage range is 0 to 10.00 Volts.

In BioTector, when the user enters the Oxygen Controller Status menu or any menu, where the oxygen gas flow will be required, the oxygen concentrator starts to operate automatically. 1. Identification. Identification is the specific identification number for the Oxygen Controller Board. 2. Version. This menu item specifies the software version of the Oxygen Controller Board. 3. Mode. This menu item allows the Oxygen Controller Board to operate the Mass Flow Controller (MFC) only, the Oxygen Concentrator only, or both. 4. Temperature Sensor. This is the BioTector temperature sensor, located on the Oxygen Controller Board, which displays the system temperature. The voltage (V) readings as obtained from the temperature sensor are displayed in real time. 5. Air Pressure Sensor. This menu item displays the air inlet pressure for the oxygen concentrator. The pressure (mbar) and the voltage (V) readings as obtained from the Air Pressure Sensor are displayed in real time. 6. O2 Pressure Sensor. This menu item displays the oxygen inlet pressure for the Mass Flow Controller. The pressure (mbar) and the voltage (V) readings as obtained from the Oxygen Pressure Sensor are displayed in real time. 7. Valve 1, 2, 3. This item displays the Oxygen Controller valve outputs for valves 1, 2 and 3. Valve 1 is the Air Isolation Valve. See figure 6 in Section 4.2.3 BioTector Oxygen Concentrator for details. Valve 2 and 3 are reserved. When Valve 1 is activated, the displayed value is “1”. When Valve 1 is deactivated, the displayed value is “0”. 8. Rotary Valve. This menu item displays the operation (Forward, Reverse and Stop) of the Rotary Valve. 9. Rotary Valve Sensor. This menu item shows the sensor position of the Rotary Valve. If the Rotary Valve is on the sensor, the displayed value is “1”. If the valve is not on the sensor, the displayed value is “0”. 10. MFC Setpoint. This menu item allows the user to test the Mass Flow Controller. Use this function to set the MFC setpoint. Press the ENTER key, set the required setpoint (e.g. 60 l/h), and press the ENTER key again. The actual flow is shown at the top of the screen. An “*” is shown when the MFC has been activated. If the flow is 0.0 l/h, then the MFC is switched off. 11. MFC Flow. When MFC Setpoint is programmed above, this menu item displays the actual flow and the corresponding voltage on the MFC. When BioTector is not running, that is, when it is powered up and stopped, or when it is in standby state, as the MFC Setpoint is 1 l/h, the MFC Flow displays the 1 l/h flow.

It is also used to reset the service counter and activate zero calibration cycles after the service is carried out. 1. Reaction Counter. This is the number of reactions performed by the BioTector. 2. Service Required In. This menu item specifies the number of days left before service is required. Note that the factory setting for this counter is typical for normal site conditions, and the service interval may have to be adjusted depending on site conditions. See Section 8.3.8 Fault Setup for details. When the BioTector is powered up, the number of days counter of the Service Required In function keeps operating regardless of the system is running or stopped. 3. Reset Service Counter. This menu item allows the user reset the service counter after the service has been completed. 4. Set Service Zero. During the service of some critical component parts in the BioTector (e.g. Sample Pump), there is a possibility for contamination of such components and this may create an unacceptable TOC offset (particularly in low range analyzers). Zero calibration may therefore be required after the BioTector removes contamination as it operates. If this occurs the zero calibration can be automatically initiated using the “Set Service Zero” function. When initiated, BioTector automatically runs a total of 5 zero calibration cycles during the following 100 online measurements (default values) and automatically adjusts the zero offset values to compensate for the removal of the contamination. It will therefore not be necessary to revisit the BioTector after the service or to repeat the zero calibration cycle. “Set Service Zero” function can be activated while the BioTector is running or stopped. An asterisk “*” mark is displayed to indicate that this function is activated. If the BioTector is stopped, the service zero calibration cycle begins when the system is started. BioTector returns online operation when the service zero calibration cycle is completed. In the example Service menu displayed above, the first number entry “20” displays the number of online reactions, which will be carried out before each service zero calibration cycle. The second number entry “5” displays the total number of zero calibration cycles. Depending on system settings, BioTector either takes DI Water as a sample or does not take any sample during the Zero Calibration cycle. See ZERO WATER in section 8.3.4.2 Zero Program for details. If DI Water is used during the Zero Calibration cycles, it is important that Zero Water (DI Water) is connected to BioTector’s Zero Water port or Manual/Calibration port (if these ports are not available, connect DI Water to Sample 1 port) before the “Set Service Zero” is activated. Typically, less than 4 liters of DI Water is sufficient to complete the Zero Calibration cycles during Service Zero. 5. Reset Service Zero. This menu item allows the user to deactivate or to stop the service zero calibration cycle (see Set Service Zero function above). When the Reset Service Zero function is selected, the asterisk “*” mark, which indicates the activation of Set Service Zero function, is removed. If Reset Service Zero function is selected during one of the zero calibration cycles, BioTector returns online operation after completing the current zero calibration cycle. Page 98 8.2 COMMISSIONING MENU The Commissioning menus are used during the commissioning and startup of the analyzer. The functions in the menus are used to program system site specific settings. Commissioning Menu Diagram 8.2.1 Reaction Time REACTION TIME 6m09s INTERVAL 0m TOTAL 6m09s ▪ REACTION TIME displays the total reaction time (in minutes and seconds) for range 1, based on all programmed settings in System Program, System Program 1 menu. ▪ INTERVAL is the time (0 minutes by default) added between each reaction. Interval can be programmed on site if frequent analysis is not necessary. The longest interval time, which can be programmed, is 1440 minutes (or 1 day). A programmed interval time would reduce the reagent usage significantly. ▪ When BioTector automatically extends the reaction time due to high level of TIC and/or TOC in the sample, if any INTERVAL time is programmed, the extended reaction time is taken out from the interval time. ▪ BioTector automatically generates an INTERVAL time when the user programs any SAMPLER, FORWARD and/or REVERSE times, which exceeds the maximum allowable time in the Sample Pump menu below. The system determines the maximum allowable time from the System Program 1 settings in System Program menu. ▪ TOTAL displays the total reaction time including the interval time if programmed. Page 99 8.2.2 Sample Pump SAMPLER FORWARD REVERSE STREAM 1 100s 60s 75s STREAM 2 100s 60s 75s STREAM 3 45s 60s …………………… MANUAL 1 50s 0s MANUAL 2 MANUAL 3 …………………… CALIBRATION 50s ▪ BioTector Sample Pump runs forward for the FORWARD time to bring a fresh sample from the STREAM, MANUAL and/or CALIBRATION points to the analyzer. This time should be long enough to guarantee a fresh sample is injected into the reactor and any old samples and bubbles are completely removed from the sample lines. ▪ BioTector Sample Pump runs in reverse for the REVERSE time so as to wash and empty the sample lines prior to the next reaction. The recommended time for REVERSE is approximately FORWARD time plus 15 seconds. See Section 8.1.1.4 Sample Pump Test to test Sample Pump operation times. ▪ The REVERSE time for a Manual Valve can only be activated if an optional Manual Bypass Valve is installed in the system. Manual Bypass Valve is used to return the previous sample into drain. ▪ If a Sampler is programmed in Stream Program menu, system automatically shows the Sampler time in this menu. The sampler time should also be long enough to guarantee that the sampler chamber is filled with fresh sample. ▪ When the user programs any SAMPLER, FORWARD and/or REVERSE times, which exceeds the maximum allowable time, BioTector generates the required INTERVAL time automatically in the Reaction Time menu above. The maximum allowable time is determined by the system from the System Program 1 settings in System Program menu. 8.2.3 Stream Program SAMPLER CONTROL NO BIOTECTOR START-UP RANGE 1 RANGE LOCKED NO PROGRAMMED STREAMS 3 ▪ If a sampler is used with the BioTector, SAMPLER is programmed (YES). When activated in this menu, the programmable Sampler time will be displayed automatically in the Sample Pump menu above. ▪ In multi-stream systems, CONTROL determines the multi-stream valve sequence to be controlled by either BIOTECTOR, or by an EXTERNAL device, or by external STREAM INPUT signals. ▪ If the CONTROL is programmed as EXTERNAL, then both multistream valve sequence and operation ranges have to be controlled by an external device. ▪ If the CONTROL is programmed as STREAM INPUT, then the multi-stream valve sequence is controlled automatically by the Stream Input signals sent from an external device. ▪ START-UP RANGE (1 by default) defines the range BioTector will use at the first reaction it starts up with. In multi-stream systems, if none of the RANGE setting for stream sequence below is programmed as AUTO, this function is automatically hidden by the system. ▪ If RANGE LOCKED (NO by default) is programmed as YES, BioTector locks the operation range at the defined RANGE above. In other words, the automatic range change function is disabled with the YES setting. ▪ In multi-stream systems, if none of the RANGE setting for stream sequence below is programmed as AUTO, this function is automatically hidden by the system. ▪ PROGRAMMED STREAMS displays the number of streams installed and programmed in Output Devices menu. Page 100 VOC CYCLE 1 TC CHECK STM 1 TC CHECK STM 2 TC CHECK STM 3 STREAM STREAM STREAM STREAM ……………… 1 , 2 2 , 1 3 , 4 - , …………… 10% 5.000mgC/l 10% 5.000mgC/l 10% 5.000mgC/l RANGE RANGE RANGE RANGE …………… 3 3 3 … ▪ VOC CYCLE determines the frequency of the TC analysis cycles and the TC TIC & NPOC analysis cycles BioTector carries out depending on the TC CHECK STREAM 1-3 concentration settings below. In other words, the TIC & NPOC analysis is carried out on a scheduled basis depending on the programmed TC CHECK STREAM 1-3 concentration levels. ▪ When the VOC CYCLE setting is 1, BioTector carries out TC TIC & NPOC analysis continuously. When the VOC CYCLE setting is for instance 10, BioTector carries out one TC TIC & NPOC analysis followed by nine TC analyses. ▪ If any of the measured TC result is outside the TC CHECK STREAM 1-3 concentration levels programmed in both % and mgC/l below, BioTector starts to carry out TC TIC & NPOC analysis as soon as the current stream program analysis sequence is complete. ▪ VOC CYCLE and TC CHECK STREAM 1-3 functions are displayed in systems operating with the VOC analysis mode. ▪ When the VOC CYCLE described above is programmed to take place at a frequency greater than 1, BioTector starts to carry out TC TIC & NPOC analysis cycle for the relevant stream, if the TC result is outside the programmed % and mgC/l bands. If the TC result is within the programmed bands, the BioTector returns to the routine TC analysis as scheduled. ▪ The BioTector operation with the programmable VOC CYCLE, and the ability of the system to automatically carry out TC TIC & NPOC analysis at a variable frequency, based on the programmable TC CHECK STREAM 1-3 concentration bands, allows the measurement of multiple parameters of the sample without a significant impact on the overall analysis cycle time. ▪ If the CONTROL is programmed as BIOTECTOR, the multistream valve sequence operates according to the STREAM and RANGE settings defined in this menu. ▪ In STREAM 1 , 2 setting, the first setting “1” represents the multistream valve number (e.g. Stream Valve 1), and the second setting “2” represents the number of reactions to be carried out at this stream before switching to the next stream. ▪ RANGE defines the operation range for each stream. In a multistream system, the ranges are locked to Range 3 by default in the factory. It is recommended to lock each stream to a particular range (e.g. 1, 2 or 3), which is appropriate to the concentration levels of the sample, in multi-stream systems. ▪ When a specific stream is programmed as “- , - - -, RANGE -“, the analysis on that stream does not take place. ▪ The AUTO (AUTOMATIC) range change function is disabled in multi-stream systems by default. If it is necessary to run any of the streams with AUTO range change function, please contact your local distributor or the manufacturer. When AUTO range change function is used, a minimum of five analysis reactions is recommended as BioTector needs to find the optimum operation range automatically. Therefore, depending on the system response, it may be necessary to discard the first two or three analysis results, when the AUTO range change function is selected for a specific stream.

When DISPLAY is programmed as “YES”, the system displays the relevant parameters on screen. When activated, the system sends the relevant 4-20mA signals for COD and BOD (in mgO/l), and for REMOVAL (in %), to the relevant result output channels if programmed. See Section 8.2.8 4-20mA Program for details. ▪ In Stream 1 1.0 0.0 setting , the first setting “1.0” acts as the “OVERALL FACTOR” and the second setting acts as the “OFFSET FACTOR” in the following equation: COD (and/or BOD) = [Overall Factor * (TOC Factor * TOC)] + Offset Factor ▪ In TC analysis mode, instead of the TOC FACTOR, the TC FACTOR is displayed in this menu and used in above equation. ▪ If the DISPLAY is programmed as COD and/or BOD above, the system multiplies the TOC result of the corresponding stream (STREAM 1-3) with the TOC FACTOR and with the OVERALL FACTOR and adds the OFFSET FACTOR to calculate the COD and/or BOD value. ▪ The STREAM FACTOR for each stream is obtained following the procedures described in information sheet “I030. TOC to COD or BOD Correlation Method”, which is available in the MMC/SD card shipped with the BioTector. ▪ Stream 1 factor is used for manual samples and calibration standards. ▪ When the display of the DW “Drinking Water” parameter is activated with the DISPLAY function above, BioTector calculates the % REMOVAL values using the measured TOC results on STREAM 1 (SAMPLE 1) and STREAM 2 (SAMPLE 2), which must be installed and connected to the INLET and OUTLET streams respectively. ▪ DETENTION TIME is a site specific time interval, during which the water flows through the water treatment plant or a treatment system to achieve a certain level of organic removal (in %) from the inlet stream (STREAM 1). This time must be programmed on site depending on site specific process conditions and requirements. BioTector uses this time to synchronize the inlet and outlet TOC measurements for the calculation of % REMOVAL. ▪ The % REMOVAL (organic removal) value is calculated as follows: REMOVAL (%) = { [ (STREAM 1 TOC Result) – (STREAM 2 TOC RESULT) ] / (STREAM 1 TOC Result) } * 100 Note that STREAM 2 (OUTLET) TOC result in above equation, is the STREAM 2 result, which is evaluated by the system after the completion of the DETENTION TIME described above. ▪ When DW display is activated, the % REMOVAL values are displayed on the Analysis Data Screen and also in the reaction archive menus. ▪ TOC < (LESS THAN) XmgC/l and X% values define various concentration levels at which a certain % REMOVAL must be achieved for a PASS or a FAIL condition. When the TOC result is measured for the INLET stream (STREAM 1), BioTector evaluates the TOC result for the OUTLET stream (STREAM 2), which is available at the end of the DETENTION TIME, and based on the measured concentration levels, the % REMOVAL value is calculated. Page 102 ▪ If the calculated % REMOVAL value is less than the corresponding expected % level programmed in this menu, BioTector displays FAIL as the RESULT on the Analysis Data Screen and records into the reaction archives. If the calculated % REMOVAL value is greater than the corresponding expected % level programmed in this menu, BioTector displays PASS as the RESULT on the Analysis Data Screen and records into the reaction archives. ▪ For example, when the TOC result of the inlet stream (STREAM 1) is 3.4mgC/l at a given time during online operation, this result falls into the “TOC < 4.0mgC/l 35%” category in this menu. If the outlet stream (STREAM 2) result available after the completion of the Detention Time, which is 32 minutes in this example menu, is 2.1mgC/l, the % REMOVAL value is 38.2%. As the 38.2% is greater than the defined 35% at this category, this is a PASS condition, because the defined minimum % organic removal from the inlet stream is achieved. If the outlet stream (STREAM 2) result is 2.8mgC/l, the % REMOVAL value is 17.6%. As the 17.6% is less than the defined 35% at this category, this is a FAIL condition, because the defined minimum % organic removal from the inlet stream is not achieved. In other words, in this example and programmed category, the TOC result of the outlet stream (STREAM 2) available at the end of the Detention Time, must be less than 2.21mgC/l for a PASS condition. ▪ When one of the Programmable Outputs is programmed as “DW FAIL” in Output Devices  Programmable Outputs menu (see section 8.3.5.2 Programmable Outputs for details), and if the % REMOVAL is a FAIL condition as described above, the relevant relay output signal is activated. When the % REMOVAL becomes a PASS condition, the output signal is deactivated. ▪ The DISPLAY function of the DW Program menu is operational in the TIC&TOC analysis type. When the ANALYSIS TYPE is changed to TC or VOC (see section 8.3.1 Analysis Mode for details), the display of the DW “Drinking Water” parameters are automatically disabled by the BioTector. 8.2.5 New Reagents Program SPAN CALIBRATION NO SPAN CHECK NO AUTOMATIC RE-START YES ▪ SPAN CALIBRATION (NO by default) defines if the Span Calibration reactions are part of the Install New Reagents procedure in Reagents Setup menu. ▪ If SPAN CALIBRATION is activated (YES), the standard solution needs to be connected to the Calibration/Manual port of the BioTector as part of the Install New Reagents procedure. See concentrations of the TOC STANDARD defined in Span Calibration menu (see Section 2.3.2 Span Calibration for details). ▪ SPAN CHECK (NO by default) defines if the Span Check reactions are part of the Install New Reagents procedure in Reagents Setup menu. ▪ Note that both SPAN CALIBRATION and SPAN CHECK functions cannot be selected as YES simultaneously and cannot occur together in the Install New Reagents procedure. ▪ AUTOMATIC RE-START (Yes by default) defines BioTector to return automatically online operation having completed the Install New Reagents cycle. Page 103 8.2.6 Reagents Monitor REAGENTS MONITOR YES LOW REAGENTS NOTE LOW REAGENTS AT 20 DAYS NO REAGENTS WARNING ACID VOLUME 19.0l ~239 DAYS BASE VOLUME 19.0l ~239 DAYS ▪ When REAGENTS MONITOR is activated (YES by default), the system creates a new Reagent Status screen which displays the amount of reagents and the estimated number of days left for each reagent to last. The Reagent Status screen is displayed for a period of 15 minutes and the system automatically reverts back to the default Reaction Result screen. ▪ BioTector calculates the reagent usage and the days remaining based on the average reagent usage from the reaction archive. If there are no reactions available in the archive, BioTector calculates the reagent usage using the operation range information in the system program menus and updates the reagent status figures accordingly. ▪ Note that when one or more reagent volumes are updated in this menu, system automatically resets the new reagents volumes in Install New Reagents menu and also updates the figures displayed in the main Reagents Status screen. ▪ LOW REAGENTS, which is programmed as NOTE (notification) by default, will activate a relay specifically programmed for notification events. ▪ When LOW REAGENTS is programmed as WARNING, and if reagents run low, system generates an “85_LOW REAGENTS” warning and activates a relay specifically programmed for warning events. ▪ LOW REAGENTS AT specifies the number of days (20 days by default), before the system generates an “85_LOW REAGENTS” warning or notification, depending on the LOW REAGENT setting above. ▪ This function can be used by the user as an early warning or notification of system low reagents so that the required reagents can be prepared or ordered in time. ▪ NO REAGENTS programmed as a WARNING event by default, can also be set as a FAULT event. When system calculates no reagents, the fault relay is activated and system generates a “20_NO REAGENTS” fault or warning. ▪ NO REAGENTS can also be programmed as NOTE (notification) where only a relay programmed as notification operates in the event of no reagents. ▪ ACID VOLUME allows the user to enter the volume of the acid reagent. When the volume is programmed, system automatically calculates the number of days acid reagent will last. ▪ BASE VOLUME allows the user to enter the volume of the base reagent. When the volume is programmed, system automatically calculates the number of days base reagent will last. ▪ It is strongly recommended that each time acid and/or base reagents are replaced or topped up, a Zero Calibration cycle is activated using the Start New Reagent Cycle function in Install New Reagents menu or using the Run Zero Calibration function in Zero Calibration menu. Page 104 8.2.7 Autocal Program TIME MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY SATURDAY SUNDAY 00:00 S Z ZS ----- CHECK CAL CAL ----- ▪ TIME (00:00 by default) schedules the Zero & Span Calibration or Check reactions time (in HR:MIN) for the weekdays if any is programmed below. ▪ In this menu, Zero and/or Span Calibration reactions and/or Check reactions are scheduled if programmed on a particular day of the week. Note that by default, there will be no scheduled zero and span cycles in the system. See Section 2.3 Calibration Menu for details. ▪ If CAL (CALIBRATION) is programmed, system generates the zero and span adjust figures which are applied to the reaction results. If CHECK is programmed, system does not generate any zero or span adjust figures. ▪ The meaning of the abbreviations used in this menu are as follows: -No function is programmed. S Span reactions only. Z Zero reactions only. ZS Zero reactions followed by Span reactions. CAL Calibration reactions CHECK Check reactions. 8.2.8 4-20mA Program OUTPUT MODE DIRECT ▪ OUTPUT MODE specifies the 4-20mA outputs operation. This parameter is programmed as: DIRECT (direct mode by default), BASIC (basic mode), STREAM MUX (stream multiplex mode) or FULL MUX (full multiplex mode). ▪ In DIRECT mode, each 4-20mA output channel is dedicated to a specific stream and result type. ▪ In BASIC mode, 4-20mA signals of zero and span calibration/check reactions are also sent to the 4-20mA channels programmed as STREAM 1. ▪ In STREAM MUX and FULL MUX modes, specific channels are dedicated to periodically change their value in steps to indicate the stream number and result type. This periodic operation reduces the number of required 4-20mA channels significantly. If STREAM MUX and FULL MUX modes are required, please contact manufacturer or distributor for the complete protocols and the details of required system configuration modifications.

The second parameter is the data type which can be programmed as TOC, TIC, TC, VOC, BOD, COD and DW%. See Section 8.2.4 COD/BOD/DW Program for details. In TIC & TOC analysis mode, TC is the sum of TIC and TOC. ▪ In CHANNEL 1 25mgC/l INST setting, the first parameter (e.g. 25mgC/l) is the full scale of the channel. The second parameter could be programmed as INST (Instantaneous) or AVRG (Average). ▪ If INST is selected, the result for the selected stream is updated at the end of each reaction. If AVRG is selected, the average result of the 24 hour reactions is updated for the specific stream at the AVERAGE UPDATE time programmed in Sequence Program, Average Program menu. ▪ When DW% (Drinking Water % REMOVAL) data type is selected, system automatically defaults to STREAM 2 (OUTLET STREAM) and the full scale of the channel is fixed to 100%. See Section 8.2.4 COD/BOD/DW Program for details. ▪ When ANALYSIS TYPE is changed in Analysis Mode menu, modifications on the 4-20mA result type and the channel full scale may be required. ▪ When SIGNAL FAULT is activated (YES) by default, if a fault occurs, system sends the FAULT LEVEL signal below for all 420mA channels. When it is set to (NO), 4-20mA outputs do not signal FAULT LEVEL if a fault occurs and system keeps sending live data on the outputs. ▪ FAULT (1.0mA by default) specifies the fault output level for all system 4-20mA channels. ▪ OUTPUT < 4mA function defines the factor (0% by default) to be applied on the stream value if the output value becomes smaller than 4mA (negative result). This function allows the user to clamp or reduce the effect of negative result on the 4-20mA output value. ▪ For instance, if the OUTPUT value is set as 100%, 100% of the negative result is sent as 4-20mA signal. If the setting is 50%, 50% of the negative results is sent as 4-20mA signal. When the setting is 0%, no negative result is send and any negative result is clamped to 4mA (0mgC/l) level. ▪ When OUTPUT MODE is programmed as BASIC above, EXCLUDE RESULTS defines the number of stream analysis reactions (3 by default) to be omitted after the zero and/or span calibration/check reactions. This is achieved by keeping the calibration output relay activated until the programmed number of stream analysis is completed. In other words, the calibration contact remains active for a programmable number of online reactions after the completion of the calibration cycle. This function helps to ignore any possible calibration impact on the system response.

In “ALARM 1 TOC STREAM 1” setting, TOC is the desired reaction result, which can also be programmed as COD, BOD, TIC, TC or VOC. STREAM 1 is the selected stream. ▪ In ALARM 1 20.0mgC/l setting, 20mgC/l defines the desired alarm activation level. The concentration level determines the alarm condition where the Alarm Relay is set or reset at the end of each reaction once the calibrated result is known. ▪ If CO2 ALARM 1-3 is not programmed in Output Devices menu, this option will not be available in this menu. ▪ CO2 ALARM 1-3 is a predictor function of a possible high TOC/TC (COD or BOD if programmed) level for a specific stream. By default, this function is disabled by 0.0ppm setting. If programmed, it provides an earlier warning of an unusually high TOC result from the rising slope of the CO2 peak generated during the reaction. ▪ If programmed, the alarm level (ppm CO2 peak) need to be selected carefully considering the temperature effect, which could be significant on the CO2 peaks. In other words, enough margins needs to be given for the settings which will create an actual early warning for an unusually high reading. At the end of the reaction, the CO2 Alarm Relay status is maintained or reset depending on the reading. In addition, this function is only suitable for multi-stream systems operating on fixed ranges, or systems operating on a single range. The use of this function is not recommended for systems which uses automatic range change. ▪ Note that in TIC & TOC and VOC analysis types, the CO2 peak used for the CO2 ALARM 1-3 is the TOC CO2 peak. In TC and TC – TIC analysis type, the CO2 peak used is the TC CO2 peak. ▪ Programmable Outputs is a link to Output Devices, Programmable Outputs menu.

TIC&TOC and VOC systems can be programmed to run in TIC+TOC, TC and VOC analysis types. If it is necessary to run a TIC&TOC system in any other analysis modes, please contact the distributor or the manufacturer. ▪ When the analysis type is changed, the system automatically modifies several system configuration parameters and resets them to their default values. Therefore, when this function is entered, before the analysis type is changed, system automatically displays a “CAUTION! CHANGING ANALYSIS TYPE ALTERS SYSTEM PARAMETERS AND REQUIRES USER TO CHANGE SYSTEM CONFIGURATION SETTINGS. PLEASE PRESS ESCAPE OR RIGHT ARROW TO PROCEED.” warning to the user to inform the user about the changes required in the system configuration settings. ▪ Systems, which are built with two or more analysis type options, are shipped with the relevant system configurations, which are available in both electronic format and as printouts. When the user changes the analysis type of the system, the necessary system configuration modifications needs to be carried out following the procedures described in information sheet “M067. BioTector Arm Configuration Upgrade Procedure”, which is available in the MMC/SD card shipped with the BioTector. When the procedures are followed, the system configuration settings will be updated automatically. Alternatively, all system configuration modifications can be carried out manually by looking at the corresponding configuration printout. TIC+TOC ▪ When DEMO MODE (OFF by default) is activated (ON), system can be started to operate in demonstration mode. In this mode, BioTector does not require any reagents or carrier gas to operate. When BioTector is started using the Operation menus, the relevant CO2 peaks are generated artificially to demonstrate the operation of the system. Because the system normal operation is inhibited, system automatically displays a warning to the user before the DEMO MODE is activated.

In TIC & TOC analysis mode, the TIC and TOC contents of a sample are measured consecutively by means of a single sample injection into a single reactor. ▪ SAMPLE PUMP is a shortcut to Commissioning, Sample Pump menu. See Section 8.2.2 Sample Pump for details. ▪ CO2 analyzer establishes a zero offset level for the ANALYZER ZERO time (15s by default) with the oxygen flow (20 l/h) settings. ▪ A “12_HIGH CO2 IN O2” fault is generated during this phase and BioTector stops if the CO2 analyzer’s reading is higher than CO2 ZERO LINE plus the CO2 ZERO ALARM value (250ppm by default) for three consecutive reactions. See Section 8.3.8 Fault Setup for details. ▪ TIC ACID specifies the amount of acid reagent (in pulses) to be injected into the reactor at range 1. ▪ SAMPLE LINE FILL defines the number of pulses Sample Pump operates forward to fill the sample tube between the Sample Valve and the Reactor Valve. ▪ SAMPLE IN defines the amount of sample (in pulses) to be injected into the reactor at operation range 1. P-V stands for “Pinch Valve”, which identifies the type of valve used during sample injection. ▪ A single pulse pump operation corresponds to ½ revolution of the pump roller. ▪ Note that any change carried out on the factory SAMPLE IN setting requires recalibration of the system. ▪ DELAY is the time (1 second by default) the carrier gas is activated to inject the reagents into the Mixer Reactor with a flow of 1 l/h by default. ▪ SAMPLE PORT PURGE defines the time (0.2 seconds by default) Sample Pump operates reverse after the sample injection. With this operation, the sample liquid, located inside the tubing between the Reactor Valve (MV3) and the T fitting, is discharged. ▪ BioTector sparges and measures the TIC content of the sample for the TIC SPARGE TIME (36s) with the oxygen flow (20 l/h) settings. ▪ If the TIC level does not drop below the TIC CHECK level (10ppm CO2 by default in Reaction Check menu) by the end of TIC SPARGE TIME, BioTector automatically extends this time (extension time) until the TIC level drops below 10ppm level. ▪ A “50_TIC OVERFLOW” warning is generated and BioTector keeps running if the TIC level does not drop below 10ppm by the end of the maximum extension time, which is 300 seconds. The maximum extension time is not a programmable function. It is a fixed figure within the system software. ▪ BASE defines the amount of base (in pulses) to be injected into the reactor for the reaction at range 1. ▪ BioTector oxidizes the sample for the BASE OXIDATION time with the oxygen flow (10 l/h) settings. If any CO2 is released during this phase, it is measured and added to the TOC result because the default setting of PEAK INTEGRATION is TOC+BASE OXID in Result Integration menu. ▪ TOC ACID states the amount of acid (in pulses) to be injected into the reactor for the TOC SPARGE phase at range 1. Page 111 TOC SPARGE TIME 75s, 20 l/h TOC OXIDATION 25s REACTOR PURGE 54s PRESSURE CHECK 20s, 40 l/h PRESSURE RELEASE 14s, 45 l/h PRESSURE PURGE 7s, 60 l/h PRESSURE RELEASE 8s,45 l/h CYCLES 0 ANALYZER PURGE 30s 40 l/h IDLE O2 FLOW 1 l/h REACTION TIME 5m25s ▪ BioTector sparges and measures the TOC content of the sample for the TOC SPARGE TIME (75s by default) with the oxygen flow (20 l/h) settings. ▪ If the TOC level does not drop below the TOC CHECK level (25ppm CO2 by default in Reaction Check menu) at the end of TOC OXIDATION TIME, BioTector automatically extends this time (extension time) until the TOC level drops below 25ppm level. ▪ A “51_TOC OVERFLOW” warning is generated if the TOC level does not drop below 25ppm at the end of the maximum extension time, which is 300 seconds. The maximum extension time is not a programmable function. It is a fixed figure within the system software. ▪ TOC OXIDATION determines the time (25s by default), the ozone generator will be running at the start of the TOC Sparge phase. Note that TOC OXIDATION time is part of the TOC Sparge phase and does not increase the TOC SPARGE TIME. ▪ REACTOR PURGE displays the overall time, the BioTector purges the Mixer Reactor. ▪ During the REACTOR PURGE phase, system continuously monitors the oxygen gas flow using the mass flow controller. If any gas leak or any flow problem is detected during this phase, BioTector generates a “06_PRESSURE CHCK FAIL” or a “02_LOW O2 FLOW - SO” fault and stops. These faults are logged into the fault archive. ▪ PRESSURE CHECK defines the time and oxygen gas flow (20 seconds at 40 l/h) the Mixer Reactor is pressurized for the REACTOR PURGE phase above. ▪ When the gas flow is equal to or less than the PRESSURE CHECK FAULT level, which is 6.0 l/h defined in Sequence Program, Pressure/Flow Test Program menu, for longer than 1 second during the PRESSURE CHECK phase above, BioTector opens the Reactor Valve (MV3) and releases the pressure of the reactor for 14 seconds at 45 l/h oxygen flow by default using the PRESSURE RELEASE function. With this process, the majority of the liquid present in the Mixer Reactor is discharged into drain through the Sample Out port. ▪ When PRESSURE RELEASE phase above is completed, using the PRESSURE PURGE function, the Mixer Reactor is pressurized once again for 7 seconds at a higher oxygen flow of 60 l/h by default. ▪ When the PRESSURE PURGE phase above is completed, BioTector opens the Reactor Valve (MV3) and releases the pressure of the reactor for 10 seconds at 45 l/h oxygen flow by default using the PRESSURE RELEASE function. ▪ Unlike the first PRESSURE RELEASE phase described above, the motor of the Mixer Reactor is activated during this phase. With this process, any remaining liquid present in the Mixer Reactor is discharged into drain through the Sample Out port. ▪ CYCLES defines the number of times the PRESSURE PURGE and the PRESSURE RELEASE phases take place during the REACTOR PURGE phase. ▪ BioTector purges the CO2 analyzer for the ANALYZER PURGE time (30s by default) with the oxygen flow (40 l/h) settings. ▪ When the BioTector is not running, that is when it is powered up and in stop state, or when it is in remote standby state, the carrier gas flow is set to 1 l/h by default. ▪ REACTION TIME displays the total reaction time (in minutes and seconds) for range 1, based on all programmed settings above.

In TC analysis mode, the TC content of a sample is measured by means of a single sample injection into a single reactor. ▪ When the Analysis Type is changed to TC, the System Program 1 menu is automatically updated with the corresponding TC system parameters. The TC system parameters, which are not covered in SYSTEM PROGRAM 1 TIC + TOC above are as follows: ▪ PRE OXIDATION defines the time (45s by default) and oxygen flow (10 l/h) settings for the initial oxidation stage, where hydroxyl radicals are generated for the VOC Oxidation phase. ▪ VOC OXIDATION states the time (45s) and oxygen flow (0 l/h no flow by default) settings for the VOC Oxidation stage, where the volatile organic carbon element of the sample is oxidized. ▪ The objective of no oxygen flow at this reaction phase is to prevent the loss of any volatiles before they are oxidized. ▪ BioTector sparges and measures the TC content of the sample for the TC SPARGE TIME (150s by default) with the oxygen flow (20 l/h) settings. ▪ If the TC level does not drop below the TC CHECK level (25ppm CO2 by default in Reaction Check menu) at the end of TC OXIDATION time, BioTector automatically extends this time (extension time) until the TC level drops below 25ppm level. ▪ A “91_TC OVERFLOW” warning is generated if the TC level does not drop below 25ppm at the end of the maximum extension time, which is 300 seconds. The maximum extension time is not a programmable function. It is a fixed figure within the system software. ▪ TC ACID states the amount of acid (in pulses) to be injected into the reactor for the TC SPARGE phase in TC mode at range 1. ▪ TC OXIDATION determines the time (75s by default), the ozone generator will be running at the start of the TC Sparge phase. Note that TC OXIDATION time is part of the TC Sparge phase and does not increase the TC SPARGE TIME. ▪ SYSTEM PROGRAM 1 VOC defines the system parameters for Oxidation Phase operation in VOC analysis mode. In VOC analysis mode, two reactions (first one in TC mode and the second one in TIC & TOC mode) are run consecutively by means of two sample injections into a single reactor. ▪ When the Analysis Type is changed to VOC, the System Program 1 menu is automatically updated with the corresponding VOC system parameters. The VOC system parameters, which are not covered in SYSTEM PROGRAM 1 TIC + TOC and TC analysis modes above is as follows: ▪ SAMPLE PUMP FORWARD 2 specifies the Sample Pump’s forward operation time (3s by default), where the Sample Pump runs forward to fill the sample line with sample liquid, prior to the second sample injection into the reactor for the second TIC & TOC analysis reaction in VOC systems.

SYSTEM PROGRAM 3 VOC 8.3.3 Calibration Data DECIMAL PLACES 3 TOC/TC CALIBRATION 1 TOC/TC CALIBRATION 2 TOC/TC CALIBRATION 3 TIC CALIBRATION 1 TIC CALIBRATION 2 TIC CALIBRATION 3 ▪ DECIMAL PLACES setting defines the number of decimal places (0, 1, 2 or 3) system displays in the reaction results and in the relevant system menus. ▪ The default unit for reaction results is mg/l “milligrams per liter”. Depending on application requirements and preferences, it is possible to configure the system to display the results in ppm “parts per million”, in µg/l “micrograms per liter” or in ppb “parts per billion”. For further information, contact your local distributor or the manufacturer. ▪ Calibration menus are used to install the calibration data and thus to calibrate the BioTector in factory. TOC CALIBRATION 1, 2 and 3 shows the calibration curves for range 1, 2 and 3 respectively. In TC and VOC systems, the TOC CALIBRATION 1/2/3 menus are named as TC CALIBRATION 1/2/3. ▪ The first column shows the number of calibration points, the second point [%] shows the calibration factors automatically calculated from the calibration data, the third column STANDARD shows the standard solution concentrations and the fourth column shows the un-calibrated result (mgC/l) measured and calculated from the CO2 analyzer readings. ▪ System calibration curves should not be modified by the user on site unless a recalibration of the system is required at a different analysis range. 8.3.4 Sequence Program 8.3.4.1 Average Program LOG AVERAGE NO AVERAGE UPDATE 00:00 ▪ LOG AVERAGE function enables (YES) or disables (NO by default) the 24-hour averaging of the reaction results in the reaction archive. ▪ The reaction results obtained from manual samples are not included in the averaging calculations. ▪ If the LOG AVERAGE above is enabled (YES), the system calculates a 24 hours average of the reaction results and displays it in the reaction archive for each stream at the time programmed for AVERAGE UPDATE (00:00, HR:MIN, by default). Page 116 8.3.4.2 Zero Program ZERO PROGRAM ZERO PROGRAM MAX ZERO AVERAGE ZERO BAND 5 , 3 , 3 2 , 2 10 3 , 0.050mgC/l ▪ In ZERO PROGRAM 5, 3, 3 setting, the first, second and third inputs define the minimum number of reactions to be carried out at Range 1, Range 2 and Range 3 respectively during the Zero Calibration and Zero Check cycles. Zero cycles are activated by RUN ZERO CALIBRATION/CHECK functions in Zero Calibration menu or by START NEW REAGENT CYCLE function in Install New Reagents menu. ▪ If two or any of the three ZERO PROGRAM settings is set to zero, system runs the zero calibration/check reactions only at the programmed range(s) and calculates the TOC Zero Adjust values for the corresponding range(s) using the measured zero adjust figure. ▪ ZERO PROGRAM MAX defines the maximum number of zero reactions system will operate at a specific range if the corresponding AVERAGE ZERO reading is not within the programmed ZERO BAND below. The corresponding AVERAGE ZERO result is calculated from the programmed number of readings defined in ZERO AVERAGE below. This parameter is common to all ranges. ▪ In ZERO AVERAGE 3, 2, 2 setting, the first, second and third inputs define the number of zero reactions to be averaged to get a representative Zero Adjust value for Range 1, Range 2 and Range 3 respectively. ▪ ZERO BAND is the mgC/l concentration band for the TOC/TC readings obtained during the Zero Calibration or Zero Check reactions. System initially runs the minimum number of reactions and calculates the average value at a specific programmed range. If the variation between the average result and each of the reaction results used in the averaging is not higher than the programmed ZERO BAND, the system completes its zero cycle and generates the necessary Zero Adjust figures. However, if any of the reaction results used in averaging is outside the band, then the system runs an additional Zero Reaction, and evaluates the readings again using the new average value. This cycle is repeated until the system obtains stable zero readings, which must be within the ZERO BAND. If stable zero readings are obtained within a certain number of reactions, which is less than or equal to the maximum number of reactions defined in ZERO PROGRAM MAX above, the Zero Adjust values are generated without any system warning. ▪ If zero stability is obtained on the executed range, system does not seek for further stability on the subsequent ranges. ▪ If the system cannot reach stable zero readings, in other words, if one or more of the TOC/TC readings are outside the programmed ZERO BAND at the end of the maximum number of reactions, depending on the type of zero cycle, system creates a “42_ZERO CAL FAIL” or a “43_ZERO CHCK FAIL” warning and logs it into the fault archive. When a “42_ZERO CAL FAIL warning occurs, system does not generate any Zero Adjust figures and continues operation using the previous Zero Adjust values. Page 117 ZERO WATER NO pH ADJUST BASE 14 , pH ADJUST TIME 60s SERVICE ZERO ZERO ADJUST HISTORY 0 , 20 , 5 0 ▪ When ZERO WATER (programmed as “NO” by default) is programmed as “YES”, BioTector takes DI Water from the available system port (which could be the ZERO WATER port or MANUAL/CALIBRATION port, and if these ports are not available SAMPLE 1 port), and uses DI Water as a sample during the Zero Calibration and Zero Check cycles. ▪ When this function is activated, the relevant system messages are also displayed in Install New Reagents menu. See section 2.2.2.1 Install New Reagents for details. ▪ The three pH ADJUST BASE parameters defines the number of pulses the base reagent pump operates to inject base reagent into the reactor at each available system operation range, which are Range 1, Range 2 and Range 3. ▪ This function is used to neutralize the pH of the Mixer Reactor. ▪ pH ADJUST TIME determines the mixing time (60 seconds by default) the Mixer Reactor operates for the pH neutralization of the reactor. ▪ SERVICE ZERO specifies the number of zero calibration cycles to be repeated after a defined number of reactions between each zero calibration cycle. The first setting “20” is the number of reactions between each zero calibration cycle, and the second setting “5” is the total number of zero calibration cycles which will be carried out. ▪ SERVICE ZERO cycle is activated by the SET SERVICE ZERO function in Service menu. ▪ Anytime the Zero Adjust value is changed, either manually by the user or automatically by the system, the new Zero Adjust value is stored in the Zero Adjust History archive with the time, date, zero range and the zero type (calibration, check or manual) information. ▪ The meaning of the codes used in the system for zero adjust are as follows: TOC/TC-ZC: Zero calibration result for TOC/TC. TOC/TC-ZK: Zero check result for TOC/TC. TOC/TC-ZM: Manually input Zero Adjust for TOC/TC.

If the Span Calibration or Span Check is programmed as YES in New Regents Program menu, START NEW REAGENT CYCLE function in Install New Reagents menu will also run the relevant span cycle. ▪ The span calibration/check reactions are run at a single range programmed by the RANGE below. System calculates and uses the same Span Adjust values for other ranges as well. ▪ SPAN AVERAGE is the number of span reactions the system averages to calculate the Span Adjust factor. ▪ RANGE (1 by default) determines the range at which all Span Calibration and Span Check reactions are carried out. ▪ TOC CALIBRATION STANDARD defines the TOC standard solution concentration level (mgC/l) to be used in Span Calibration reactions. ▪ If TOC CALIBRATION STANDARD is programmed as 0.0mgC/l, system ignores the Span Calibration results and omits any related warnings defined in TOC BAND below. ▪ TOC CHECK STANDARD defines the TOC standard solution concentration level (mgC/l) to be used in Span Check reactions. ▪ If TOC CHECK STANDARD is programmed as 0.0mgC/l, system ignores the Span Check results and omits any related warnings defined in TOC BAND below. ▪ TIC CALIBRATION STANDARD defines the TIC standard solution concentration level (mgC/l) to be used in Span Calibration reactions. ▪ If TIC CALIBRATION STANDARD is programmed as 0.0mgC/l, system ignores the Span Calibration results and omits any related warnings defined in TIC BAND below. ▪ In TC systems, TIC CALIBRATION STANDARD is not displayed. ▪ TIC CHECK STANDARD defines the TIC standard solution concentration level (mgC/l) to be used in Span Check reactions. ▪ If TIC CHECK STANDARD is programmed as 0.0mgC/l, system ignores the Span Check results and omits any related warnings defined in TIC BAND below. ▪ In TC systems, TIC CHECK STANDARD is not displayed. Page 119 TC CAL STD 15.0mgC/l TC CHECK STD 15.0mgC/l TOC BAND 25% TIC BAND 25% TIC FACTOR = TOC YES SPAN ADJUST HISTORY ▪ In VOC systems, the sum of the TIC and TOC Calibration Standard solution is displayed as TC Calibration Standard. When TOC Calibration Standard is programmed as 0.0mgC/l above, and when a concentration of TIC Calibration Standard is programmed above, BioTector displays the TC Calibration Standard as 0.0mgC/l on purpose. This allows the calibration of TIC without any effect on the TC calibration. In other words, as programmed, system ignores the TC span calibration results and omits any TC related warnings. ▪ In VOC systems, the sum of the TIC and TOC Check Standard solution is displayed as TC Check Standard. When TOC Check Standard is programmed as 0.0mgC/l above, and when a concentration of TIC Check Standard is programmed above, BioTector displays the TC Check Standard as 0.0mgC/l on purpose. This allows the check of TIC without any effect on the TC check. In other words, as programmed, system ignores the TC span check results and omits any TC related warnings. ▪ TOC BAND determines the tolerance limits (25% by default) for the Span Calibration or Span Check reaction results for TOC. ▪ In TC and VOC systems, this function is named as TC BAND. ▪ If the average span result is outside the tolerance limits, a “30_TOC/TC SPAN CAL FAIL” or “33_TOC/TC SPAN CHCK FAIL” warning is logged depending on system analysis mode. ▪ TIC BAND determines the tolerance limits (25% by default) for the Span Calibration or Span Check reaction results for TIC. ▪ If the average span result is outside the tolerance limits, a “31_TIC SPAN CAL FAIL” or “34_TIC SPAN CHCK FAIL” warning is logged. ▪ If the TIC FACTOR = TOC is selected as “YES” (by default), the TOC span factor is used for TIC. ▪ If the TIC FACTOR = TOC setting is “YES”, when the TOC Span Adjust value is changed, the TIC Span Adjust value will also change automatically. ▪ In VOC systems, this function is named as TIC FACTOR = TC. ▪ Anytime the Span Adjust value is changed, either manually by the user or automatically by the system, the new Span Adjust factor is stored in the Span Adjust History archive with the time, date, span RANGE, span type (calibration or check) and the standard solution used. ▪ The meaning of the codes used in the system for span adjust are as follows: TOC/TC/TIC-SC: Span calibration result for TOC/TC/TIC. TOC/TC/TIC-SK: Span check result for TOC/TC/TIC. TOC/TC/TIC-SM: Manually input span adjust for TOC/TC/TIC.

The reagent priming and the subsequent reactor purge operation is repeated 4 times by default. ▪ The reagent purge is activated by START NEW REAGENT CYCLE function in Install New Reagents menu or alternatively by RUN REAGENTS PURGE function in Zero Calibration menu. ▪ The REACTOR ACID/BASE FILL time defines the quantity of acid and base reagents injected into the reactor at the end of the ACID & BASE PURGE phase described above. ▪ When the acid and base reagents are injected into the reactor, the reagents are mixed in the reactor for the duration of REACTOR WASH time (100 seconds by default) to balance and neutralize the reactor pH. Pressure/Flow Test Program TIME 08:15 PRESSURE TEST FAULT 6.0l/h PRESSURE TEST WARN 4.0l/h ▪ BioTector performs an automatic pressure and flow test every day at the TIME programmed (at 08:15 hours by default). ▪ Each time BioTector is started up and every day during online operation at the programmed TIME above, BioTector pressurizes the system with oxygen gas and uses its mass flow controller to detect any gas leak in the system. If the measured flow is less than or equal to the programmed PRESSURE TEST FAULT flow level (6.0 l/h by default), the pressure test passes. ▪ If the flow is greater than programmed PRESSURE TEST FAULT setting, the pressure test fails, and BioTector generates a “05_PRESSURE TEST FAIL” fault and stops. This fault is logged in the fault archive. In TC – TIC systems, BioTector generates a “07_TIC PRESSURE FAIL” fault if TIC reactor pressure test fails. ▪ The pressure test cycle can be disabled by setting PRESSURE TEST FAULT setting to 0.0 l/h. When disabled, BioTector automatically displays an “OFF” message on the screen and logs a “29_PRESSURE TEST OFF” warning in the fault archive. ▪ If the pressure test is skipped during the startup sequence with the “Quick Startup” function (see Section 2.2.1 Start Stop for details) a “28_NO PRESSURE TEST” warning is logged in the fault archive. This warning cannot be acknowledged by the user, it can only be acknowledged automatically by the system the next time the pressure test is passed. ▪ PRESSURE TEST WARNING, which is typically 30% less than the PRESSURE TEST FAULT setting (4.0 l/h by default), gives an advanced warning of a possible gas leak in BioTector. ▪ The pressure warning can be disabled by setting PRESSURE TEST WARNING to 0.0 l/h. When disabled, BioTector automatically displays an “OFF” message on the screen. ▪ If the flow measured during Pressure Test is less than or equal to 6.0 l/h but greater than 4.0 l/h, BioTector generates a “26_PRESSURE TEST WARN” and continues to run. The warning is logged in the fault archive. In TC – TIC systems, BioTector generates a “27_TIC PRESSURE WARN” if TIC reactor pressure test fails. Page 121 PRESSURE CHCK FAULT FLOW WARNING REACTOR PURGE CHECK REACTOR PURGE BAND 6.0l/h 45.0l/h 4s 3.0l/h ▪ At the end of each reaction during operation, BioTector automatically pressurizes the system with oxygen gas and uses its mass flow controller to detect any gas leak in the system. If the measured flow is less than or equal to the programmed PRESSURE CHECK FAULT flow level (locked to 6.0 l/h by default) during the test, the pressure check passes. The PRESSURE CHECK FAULT acts a safety function, to ensure that there is no gas leak in the system and it is safe to start the next analysis reaction. ▪ The pressure check cycle cannot be disabled in the system. ▪ If the flow measured during the pressure check is greater than the programmed PRESSURE CHECK FAULT level (greater than 6.0 l/h) the pressure check fails, and BioTector generates a “06_PRESSURE CHCK FAIL” fault and stops. This fault is logged in the fault archive. ▪ Each time BioTector is started up and everyday during online operation at the programmed TIME above, oxygen gas flows through the system and mass flow controller is used to detect any blockage in the system. If the measured flow is greater than or equal to the programmed FLOW WARNING level (45.0 l/h by default), the flow test passes. ▪ If the measured flow is less than the programmed FLOW WARNING setting, the flow test fails, and BioTector generates a “22_FLOW WARNING - EX” or “23_FLOW WARNING - SO” in the fault archive and continues to run. This warning is logged in the fault archive. ▪ In TC – TIC systems, BioTector generates a “24_TIC FLOW WARN - EX” or “25_TIC FLOW WARN - SO” if TIC reactor flow test fails. ▪ During the two Pressure Release phases of the Reactor Purge carried out at the end of each analysis cycle described in section 8.3.2 System Program, BioTector monitors the oxygen gas flow for 4 seconds (by default) with the REACTOR PURGE CHECK function. This is carried out to detect any irregularities in the gas flow, which may indicate a possible blockage or restriction in the reactor and/or in the sample out lines, which includes Reactor Valve (MV3) and Sample Valve (MV4). ▪ If the monitored oxygen gas flow readings during the REACTOR PURGE CHECK are not stable and move outside the REACTOR PURGE BAND, which is programmed as ±3 l/h by default, during the first Pressure Release phase for three consecutive times, a “128_REACTOR PURGE WARN” warning is logged in the fault archive and BioTector keeps running. ▪ If the monitored oxygen gas flow readings are not stable and move outside the REACTOR PURGE BAND during the second Pressure Release phase and if a flow problem has already been detected during the first Pressure Release phase of the same Reactor Purge cycle, a “129_REACTOR PURGE FAIL” fault is logged in the fault archive and BioTector stops.

If the default SPF (SAMPLE PUMP FORWARD) option is selected, the valve for the next stream is selected as the Sample Pump starts to run forward to bring the sample from the next stream. If SPR (SAMPLE PUMP REVERSE) option is selected, the valve for the next stream is selected when the Sample Pump reverse operation is completed for the current stream, or when the BioTector powers up. ▪ If SAMPLER is activated in Stream Program menu, SPF option is displayed as SPF/SAMPLER. ▪ OUTPUT 1-6 menus typically contain internal output settings related to system operation. These relay outputs, located on the Motherboard, are system optional features. ▪ STREAM 1 is always functional as default within the system software. OUTPUT 4-6 menus are not displayed as they are reserved for future use. ▪ OUTPUT 1-6 relays are programmed to a single output function or to multiple output functions if the relevant option has been installed in the BioTector. The programmed output function or functions are marked with an asterisk “*” sign in these menus as in the example for OUTPUT 1, which is programmed for MAINTANENCE SIGNAL and CALIBRATION SIGNAL below. ▪ When multiple functions are programmed for an output relay, the relay output is activated when one or multiple conditions are initiated. In the example below, OUTPUT 1 is activated when MAINTANENCE SIGNAL or CALIBRATION SIGNAL is triggered. ▪ In BioTector configuration data download (or in All Data download), the programmed output functions for each output is tabulated and marked with asterisk “*” signs for clarity.

Page 125 8.3.6 Reaction Check CO2 LEVEL FAULT TYPE 100ppm, AUTO WARNING REACTION COUNT 3 TIC CHECK 7ppm TOC CHECK 25ppm TC CHECK 25ppm ▪ Due to the organic and inorganic contamination in the BioTector reagents, every TOC/TC reaction will generate a small level of CO2 from the reagents alone even if there is no sample present. The first setting (100ppm by default) of CO2 LEVEL specifies the reaction check CO2 level, which is the minimum expected CO2 reading in ppm measured by the CO2 Analyzer in a reaction. ▪ The second setting (AUTO by default) of CO2 LEVEL defines the reaction check CO2 level mode. When programmed as AUTO, BioTector automatically sets the CO2 LEVEL to 60% of the average CO2 peak reading recorded during the Zero Calibration or Zero Check reactions. If it is set as MAN (Manual), system uses the fixed programmed CO2 LEVEL value. ▪ BioTector looks for first an increase and then a decrease in the CO2 peak data during the TOC phase (or TC phase depending on ANALYSIS TYPE). If the CO2 peak occur at the wrong phase of the reaction and/or if the CO2 peak is smaller than the expected CO2 LEVEL (100ppm by default) for the number of consecutive reactions defined by REACTION COUNT below (3 reactions by default), system generates a “04_REACTION ERROR” warning or a “04_REACTION ERROR” fault (depending on the FAULT TYPE setting below) and logs into the fault archive. ▪ When CO2 LEVEL is programmed as 0ppm, the reaction check function will be disabled. Reaction check function is omitted during the zero calibration or zero check reactions. ▪ FAULT TYPE determines the type (WARNING or FAULT) of the “04_REACTION ERROR” fault. ▪ When “04_REACTION ERROR” fault occurs, if FAULT TYPE is programmed as WARNING (by default), BioTector keeps running. If it is programmed as FAULT, BioTector stops. ▪ REACTION COUNT defines the number of consecutive reactions (3 by default) before a “04_REACTION ERROR” fault is triggered. ▪ TIC CHECK (7ppm CO2 by default) represents the CO2 check point in the TIC phase. If the CO2 level is above the programmed check point at the end of the TIC phase, then the system automatically extends the TIC SPARGE TIME by 1 second and checks the CO2 level again. If the TIC level does not drop below the check point at the end of the maximum 300 seconds, a “50_TIC OVERFLOW” warning is generated. ▪ TOC CHECK (25ppm CO2 by default) represents the CO2 check point in the TOC phase. If the CO2 level is above the programmed check point at the end of the TOC Oxidation section of the TOC phase, then the system automatically extends the TOC SPARGE TIME and TOC OXIDATION time by 1 second and checks the CO2 level again. If the TOC level does not drop below the check point at the end of the maximum 300 seconds, a “51_TOC OVERFLOW” warning is generated. ▪ In TC and VOC systems, TC CHECK (25ppm CO2 by default) represents the CO2 check point in the TC phase. If the CO2 level is above the programmed check point at the end of the TC Oxidation section of the TC phase, then the system automatically extends the TC SPARGE TIME and TC OXIDATION time by 1 second and checks the CO2 level again. If the TC level does not drop below the check point at the end of the maximum 300 seconds, a “91_TC OVERFLOW” warning is generated. Page 126 8.3.7 Result Integration TOC INTEGRATION 3 TOC INT. LIMITS 10% , 0.100 ▪ TOC INTEGRATION (3 by default) defines the number of reaction results to be averaged to get the actual TOC result. ▪ TOC INTEGRATION LIMITS controls the averaging function defined in TOC INTEGRATION above. The first parameter “10%” defines the % band variation and the second parameter “0.100” defines the absolute variation in mgC/l. If the reaction result is outside the specified bands (TOC INTEGRATION LIMITS), then the reaction result averaging is omitted. In other words, the result, which is outside the TOC INTEGRATION LIMITS, is displayed at the end of the reaction without averaging. If the result is within the TOC INTEGRATION LIMITS, the averaging function is continued and the programmed number of reaction results (defined in TOC INTEGRATION above) is averaged. Page 127 8.3.8 Fault Setup LOW O2 FLOW TIME 12s HIGH O2 FLOW TIME 20s BASE CO2 ALARM 250ppm CO2 ZERO LINE 0ppm , AUTO CO2 ZERO ALARM 250ppm SERVICE COUNTER 180 DAYS ▪ If the O2 flow drops more than 50% of the MFC set value for longer than the LOW O2 FLOW TIME (12s by default), a “01_LOW O2 FLOW - EX” or “02_LOW O2 FLOW - SO” fault is logged. ▪ If the O2 flow increases more than 50% of the MFC set value during any reaction phase for longer than the HIGH O2 FLOW TIME (20s by default), a “03_HIGH O2 FLOW” fault is logged. ▪ During the zero calibration & zero check reactions, system monitors the CO2 peak level with the CO2 Analyzer. If the monitored value is higher than the programmed BASE CO2 ALARM level (250ppm by default), a “52_HIGH CO2 IN BASE” warning is logged into the fault archive. ▪ In the event of a “52_HIGH CO2 IN BASE” warning, BioTector generates the relevant Zero Adjust factors automatically, at the end of a successfully completed Zero Calibration cycle. ▪ When it is set as AUTO (Automatic by default), the CO2 ZERO LINE value is updated automatically by the system during Analyzer Zero phase. If it is set as M (Manual), the set value in ppm is used as the fixed CO2 zero line. ▪ For instance, if there is a CO2 leak into the CO2 analyzer’s source or detector sections, a typical of 400ppm CO2 level in the environment will increase the CO2 ZERO LINE level to ≈250ppm within 24 days of online operation or approximately after 5000 analysis cycles. ▪ If the concentration of CO2 measured during the Analyzer Zero phase for the oxygen gas input is higher than CO2 ZERO LINE plus CO2 ZERO ALARM (250ppm by default) value for 3 consecutive reactions, a “12_HIGH CO2 IN O2” fault is logged in the fault archive and the system stops. ▪ The purpose of this function is to monitor the operation of the oxygen concentrator. If the oxygen concentrator fails, then the oxygen purity will be reduced and CO2 at atmospheric levels (~400ppm) will enter the BioTector, and will be detected by the CO2 analyzer. It is important not to run the BioTector with a faulty oxygen concentrator as eventually water could enter the BioTector with the contaminated oxygen gas, which may cause damage on the Mass Flow Controller. ▪ SERVICE COUNTER (180 days by default) specifies the number of days the system operates before triggering an “83_SERVICE TIME” warning. ▪ Note that the service counter keeps operating and decreases the count by a day if system is powered up during the same day even though system was not running. Because the default factory setting is a typical value for normal site conditions, the service interval may need to be adjusted according to specific site conditions. Page 128 OZONE TEST TIME 18s OZONE GEN ALARM 0.50A , 5s OZONE GEN FAN ALARM 0.00V , 5s SAMPLE STATUS 5s , ARCHIVE NO AUTO RESET NO SAMPLE FAULT 1 SAMPLE FAULT 2 SAMPLE FAULT 3 AUTO RESET 75% 1000s 1000s 1000s NO ▪ OZONE TEST TIME defines the programmed time (18 seconds by default), which passes the Ozone Test in Process Test, Ozone Test menu. The maximum time the ozone generator remains on during the Ozone Test is 60 seconds. ▪ OZONE GENERATOR ALARM defines the current (0.5A by default) and the time (5 seconds by default) setting for the “102_OZONE GEN FAULT” event. If the current drawn through the Ozone Generator has dropped below 0.5 Amp for longer than 5 seconds, BioTector generates a “102_OZONE GEN FAULT” warning. ▪ OZONE GENERATOR FAN ALARM defines the Voltage Band (0.0V by default) and the time (5 seconds by default) settings for the “103_OZONE FAN FAULT” event. If the voltage on the Ozone Generator Fan drops below 2.5V minus the Voltage Band (i.e. 1.5V by default), or if the voltage increases more than 2.5V plus the Voltage Band (i.e. 3.5V by default), for longer than 5 seconds, BioTector generates a “103_OZONE FAN FAULT” warning. ▪ When OZONE GENERATOR FAN ALARM voltage is set to 0.0 Volt, then the Ozone Fan Fault generation is switched off. ▪ The first parameter in SAMPLE STATUS setting is the sample detection time (5 seconds by default) BioTector processes the output of the Sample Sensor. When the parameter is set to 0s (zero seconds), the sample detection is switched off. The second parameter (75% by default) is the % sample quality threshold, which is used to activate SAMPLE STATUS output. ▪ Sample Status output is activated (energized) when BioTector Sample Sensor detects no sample or when the sample quality is less than the default 75% threshold value (i.e. when there is significant quantity of air bubbles in the stream/manual grab sample lines). ▪ Sample Status output is set/reset as soon as the Sample Sensor signal is processed. Sample Status holds its state between reactions and when system is stopped or put into standby mode. ▪ In systems built with Sample Sensor, if SAMPLE STATUS ARCHIVE function is programmed as “YES”, the “116/117/118 LOW/NO SAMPLE 1/2/3” notification events are generated and logged into the Fault Archive when there is no or low sample liquid in the corresponding streams from stream 1 to stream 3. ▪ If SAMPLE STATUS AUTO RESET function is programmed as “YES”, the corresponding “116/117/118 LOW/NO SAMPLE 1/2/3” notification events are automatically acknowledged in the Fault Archive depending on the sample status of the relevant streams from stream 1 to stream 3. ▪ In multi-stream systems, the Sample Status relay output signal is a common signal, which is activated/deactivated when the sample quality is determined by the BioTector Sample Sensor for any of the streams during analysis. ▪ SAMPLE FAULT 1-3 defines the stream specific programmable output time delay (1000 seconds by default), which delays the activation of the SAMPLE FAULT 1-3 output signals and logging of the “122/123/124 SAMPLE FAULT 1/2/3” notification events into the fault archive. The purpose of the time delay is to prevent unnecessary generation of the sample fault signals if the sample fault only occurs for a very short time. ▪ SAMPLE FAULT AUTORESET determines whether the “122/123/124 SAMPLE FAULT 1/2/3” notification events are automatically acknowledged by the system (with the “YES” setting) or to be acknowledged manually from the BioTector keyboard (with the “NO” setting by default). Page 129 COOLER ALARM 0.10A , 5s COOLER FAN ALARM 1.00V , 5s SIGMATAX FLT DELAY 900s ▪ COOLER ALARM defines the current (0.1A by default) and the time (5 seconds by default) setting for the “107_COOLER FAULT” event. If the current drawn through the Cooler has dropped below 0.1 Amp for longer than 5 seconds, BioTector generates a “107_COOLER FAULT” warning. ▪ When COOLER ALARM current is set to 0.0 Amp, then the Cooler Fault generation is switched off. ▪ COOLER FAN ALARM defines the Voltage Band (1.0V by default) and the time (5 seconds by default) settings for the “108_COOLER FAN FAULT” event. If the voltage on the Cooler Fan drops below 2.5V minus the Voltage Band (i.e. 1.5V by default), or if the voltage increases more than 2.5V plus the Voltage Band (i.e. 3.5V by default), for longer than 5 seconds, BioTector generates a “108_COOLER FAN FAULT” warning. ▪ When COOLER FAN ALARM voltage is set to 0.0 Volt, then the Cooler Fan Fault generation is switched off. ▪ The SIGMATAX FAULT DELAY function is displayed in systems programmed to operate with the Sigmatax Sampler. ▪ The SIGMATAX FAULT DELAY defines the time (900 seconds by default) during which any problems with the “sample ready” signals, sent from the Sigmatax Sampler to the BioTector, are ignored. ▪ When there is a problem with the “sample ready” signals, (i.e. when the IR signal sent from Sigmatax Sampler is low for longer than the SIGMATAX FAULT DELAY time or when the IR signal is high for longer than 3600 seconds), BioTector logs a “130_NO SIGMATAX SIGNAL” fault and stops. ▪ When Sigmatax Sampler sends an error signal to the BioTector for longer than 60 seconds, BioTector logs a “131_ SIGMATAX FAULT” fault and stops. Page 130 8.3.9 Fault Status This menu gives a short status history of several system devices before a fault is registered. The default 0.0 values indicate that there are no faults detected for the specific device. O2 FLOW BIOTECTOR TEMPERATURE CO2 ANALYZER FAULT OZONE GEN FAULT COOLER FAULT ▪ The O2 FLOW menu consists of 120 entries for the MFC setpoint value (first column) and MFC flow value (second column). The entries are sampled at every 1 second intervals. If a fault is detected, the events are stored in the O2 FLOW fault archive and are retained even if the fault is acknowledged in Fault Archive menu. The archive is only over-written if a new fault is detected. ▪ The BIOTECTOR TEMPERATURE menu consists of 120 readings of the BioTector temperature. The entries are sampled at every 2 seconds intervals, covering 240 seconds. If a fault is detected, the events are stored in the BIOTECTOR TEMPERATURE fault archive and are retained even if the fault is accepted in Fault Archive menu. The archive is only overwritten if a new fault is detected. ▪ The CO2 ANALYZER FAULT menu consists of 120 readings of the CO2 Analyzer. The entries are sampled at every 2 second intervals, covering 240 seconds. If a fault is detected, the events are stored in the CO2 ANALYZER FAULT archive and are retained even if the fault is accepted in Fault Archive menu. The archive is only over-written if a new fault is detected. ▪ The OZONE GENERATOR FAULT menu consists of 120 readings of the current drawn through the OZONE GENERATOR. If a fault is detected, the events are stored in the OZONE GENERATOR FAULT archive and are retained even if the fault is accepted in Fault Archive menu. The archive is only over-written if a new fault is detected. By careful analysis of the fault data, it is possible to determine between an abrupt fault, and an intermittent fault. ▪ The COOLER FAULT menu consists of 120 readings of the Cooler. The entries are sampled at every 1 second intervals. The data in first column displays the current drawn by the Cooler in Amperes. The data in the second column displays the % output activation time of the Cooler. For instance, 90% means that the Cooler is activated for 90% of the Pulse Width Modulation period. If a fault is detected, the events are stored in the COOLER FAULT archive and are retained even if the fault is accepted in the Fault Archive menu. The archive is only overwritten if a new fault is detected. Page 131 8.3.10 CO2 Analyzer ANALYSIS GRAPH SCALE 5000ppm BAUDRATE 9600 CO2 ANALYZER RANGE 10000ppm CO2 ANALYZER CAL ▪ ANALYSIS GRAPH SCALE (5000ppm by default) determines the scale of the y-axis “CO2 analyzer’s ppm-CO2 readings” on the Analysis Graph Screen (see section 2.1.4 Analysis Graph Screen for details). This function allows the system to display CO2 data peaks in optimal resolution on the LCD screen. ▪ The ANALYSIS GRAPH SCALE is independent of the CO2 ANALYZER RANGE described below. Note that, in certain circumstances, when the displayed CO2 peaks on screen exceeds the scale of the graph, the CO2 analyzer keeps measuring and integrating the CO2 readings to obtain the TOC result, without losing any CO2 data. ▪ BAUDRATE (9600bps by default) specifies the data communication signaling speed of CO2 Analyzer with the RS232 communication interface. ▪ CO2 ANALYZER RANGE defines the full scale range of the CO2 analyzer installed in the BioTector. ▪ The CO2 ANALYZER CALIBRATION menu allows the user to change CO2 Analyzer range and the CO2 analyzer zero and span parameters when necessary. If required, please contact manufacturer or distributor for details of the procedures. Page 132 8.3.11 Cooler Program MODE T CONTROL BACKUP PWM DUTY 10% 50% PWM OFFSET 14.0C 50% PWM SLOPE 5.00%/C T DIFFERENCE 16.0C ▪ MODE defines the operation mode of the Cooler. Cooler operates automatically with the default TEMPERATURE CONTROL setting, to achieve the programmed TEMPERATURE DIFFERENCE below. ▪ When MODE is programmed as PWM “PULSE WIDTH MODULATION”, the Cooler operates using the BACKUP PWM DUTY setting below. ▪ BACKUP PULSE WIDTH MODULATION DUTY defines the operation of the cooler in back-up mode, i.e. when there is a fault with the Cooler or with the BioTector temperature sensor (i.e. when system generates 107_COOLER FAULT and/or 108_COOLER FAN FAULT or 113_TEMP SENSOR FAULT warning events). The default 10% setting means that the Cooler is activated for 10% of the time and deactivated for 90% of the time. ▪ The BACKUP PWM DUTY mode is automatically cancelled when the relevant faults are acknowledged in the Fault Archive menu. ▪ The 50% PWM OFFSET setting (14°C by default) is the midpoint offset of the cooler temperature calibration curve, which is linear. When Cooler operates with PULSE WIDTH MODULATION at 50%, the Cooler temperature is typically ~14°C below ambient temperature, which is ~25°. ▪ The 50% PWM slope setting (5% per 1°C by default) is the slope of the cooler temperature calibration curve at midpoint. When Cooler operates with PULSE WIDTH MODULATION at 50%, the Cooler temperature changes by ~1°C with every 5% change in PULSE WIDTH MODULATION. ▪ TEMPERATURE DIFFERENCE (16°C by default) defines the temperature difference to be achieved between the BioTector temperature and the Cooler temperature. BioTector temperature sensor is located on the O2-Controller Board. Cooler temperature is achieved with the settings described above. ▪ Cooler Temperature = BioTector Temperature – TEMPERATURE DIFFERENCE. ▪ When BioTector detects that the Cooler temperature will drop below 5°C applying above settings, system automatically decreases the PULSE WIDTH MODULATION so that the temperature of the Cooler does not drop below 5°C. This is carried out to avoid possible freezing of the condensate water, which could be present inside the Cooler.

The default 50% settings mean that the Ozone Destructor Heater is on for 50% of the time, which is typically 5 seconds on and 5 seconds off during normal operation. ▪ When the temperature of the BioTector exceeds 40°C for more than 2 minutes, system automatically applies a PWM DUTY setting of 10%, which means that the Ozone Destructor Heater is on for 10% of the time, which is typically 1 second on and 9 seconds off. ▪ When the temperature of the BioTector is below 15°C for more than 2 minutes, system automatically applies a PWM DUTY setting of 100%, which means that the Ozone Destructor Heater is on all the time. When system automatically changes the operation of the Ozone Destructor Heater, no system warnings are generated. ▪ PURGE CYCLE MODE, which is automatically controlled (AUTO by default), specifies how the purging of the Ozone Destructor is carried out. In AUTO (Automatic) mode, the Ozone Destructor heater and the BioTector Cooler are controlled by the PURGE CYCLE FLOW and AUTO PURGE CYCLE parameters defined below. ▪ When PURGE CYCLE MODE is OFF, the Ozone Destructor heater and the Cooler operate normally. ▪ When PURGE CYCLE MODE is programmed as MAN (Manual), the Ozone Destructor heater and the Cooler operates as described in MAN PURGE CYCLE below. ▪ When the PURGE CYCLE MODE above is programmed as MAN above, in MANUAL PURGE CYCLE setting, the first parameter (2000 by default) defines the number of analysis cycles the Ozone Destructor and the BioTector Cooler operates as normal. The second parameter (15 by default) defines the number of analysis cycles the Ozone Destructor heater is switched off. The third parameter (15 by default) defines the number of analysis cycles both the Ozone Destructor heater and the Cooler are switched off. ▪ When MANUAL PURGE CYCLE is selected, above operation routine is repeated with the relevant number of programmed analysis cycles. ▪ This menu item is only displayed, when the PURGE CYCLE MODE operation mode is selected as MAN above. ▪ When the PURGE CYCLE MODE above is programmed as AUTO, and if the flow measured during the Flow Test (see Section 8.3.4.5 Pressure/Flow Test Program for details) is below the default PURGE CYCLE FLOW setting of 48 l/h, the Ozone Destructor heater and the Cooler operates as described in AUTO PURGE CYCLE below. ▪ This menu item is only displayed, when the PURGE CYCLE MODE operation mode is selected as AUTO above. ▪ When the PURGE CYCLE MODE above is programmed as AUTO above, in AUTOMATIC PURGE CYCLE setting, the first parameter (15 by default) defines the number of analysis cycles the Ozone Destructor heater is switched off. The second parameter (also 15 by default) defines the number of analysis cycles both the Ozone Destructor heater and the Cooler are switched off. The AUTO PURGE CYCLE operation routine is carried out only once after the Flow Test routine. ▪ This menu item is only displayed, when the PURGE CYCLE MODE operation mode is selected as AUTO above.

Please note that any special models and applications may require additional service items. Service procedures may be changed without notice due to the continuous research and development program. Therefore, please refer to the service check list supplied with the service kit for most up to date information. Detailed service procedures are available in a presentation format in the MMC/SD card shipped with the BioTector. It is recommended to review this document before starting the service procedures. Service should only be carried out when “SYSTEM STOPPED” message is displayed on the top left corner of the main Analysis Data screen or when the system is powered down. When “REMOTE STANDBY” or “SYSTEM RUNNING” message is displayed on the screen, stop the BioTector using the “Finish & Stop” or “Emergency Stop” function. For system and personal safety, all reagent lines should be washed with water and then purged with air before the service procedures are carried out. In order to wash the reagent lines, connect all reagent dip tubes to a DIW (or tap water) container. Go to Zero Calibration menu and activate “RUN REAGENT PURGE” function to wash the reagent lines with water (see Section 2.3.1 Zero Calibration for details). When the reagent purge with water is completed, remove the tubes from the water container and place them open to air. Using the same menu, select the “RUN REAGENT PURGE” function one more time to purge the reagent lines with air. As the system may still contain small traces of reagents after the reagent purge cycles, it is strongly recommended to take the necessary safety precautions, such as wearing eye protection and gloves throughout the service. (If the reagents lines do not fill with DIW during the Reagents Purge cycle, raise the DIW container above the height of the BioTector, go to Zero Calibration menu and select the RUN REAGENTS PURGE function again.) Disconnect power to ozone destructor heater. The ozone destructor should never be opened when it is hot as the threads may seize. _____ Replace the 6.4mm OD, 3.2mm ID EMPP 562 tubing used in the Sample Valve (see item C1 in the service kit). _____ Check the rollers on the rotor of the WMM60 Sample Pump manually and confirm that they are rotating freely. _____ Replace the tubing (6.4mm OD, 3.2mm ID EMPP 562 tubes) of the WMM60 Sample Pump. The WMM60 replacement tubes are supplied in the service kits (see item C2 in the service kit). The overall length of the tube is 156.5mm. If process conditions require this tube to be changed every 3 months, an additional tube is supplied in the service kit. _____ Replace the 6.4mm OD, 3.2mm ID EMPP 562 tubing used in the pinch valves (see item C1 in the service kit) and any PP (Poly-Propylene) Y fittings (see item C3 in the service kit) in the analyzer. If additional Y fittings are required they should be ordered separately. _____ Disconnect the PFA fitting above the cooler. Remove the three nuts and open the analysis door. Using the Simulate menu (see Section 8.1.2 Simulate for details) and referring to figure 1, figure 2 and table 2 in Section 4.1.1 Analysis Enclosure, check and confirm that the valves are operating and there are no leaks: Check Sample Valve, MV4. _____ Check Reactor Valve, MV3 operation. When the valve is activated, the LED on the valve should be on. _____ Check Exhaust Valve, MV1. When the valve is activated, the LED on the valve should be on. _____ Check all the other valves (e.g. multi-stream valves) if installed in the BioTector. _____ Check and confirm that MANUAL/CALIBRATION ports are not blocked or isolated. _____ Page 152 Check for possible build-up of salts or any material at any of the PFA T fittings located between the Ozone Generator and the Mixer Reactor. Clean the fittings and/or the tubing if necessary. _____ Remove Ozone Line Filter and wash it with DIW (or tap water). Dry the filter well and reinstall in place. See figure 1, table 2 in Section 4.1.1 Analysis Enclosure and figure 4 in Section 4.2.2 BioTector Sample Injection for details. _____ Using the Simulate menu (see Section 8.1.2 Simulate for details) and a 10ml graduated cylinder, check and confirm that the pumps are pumping correctly. Acid Pump rate for FMM20 Pump at 400 pulses should be between 3.80 ml and 4.20 ml. (Depending on the quantity of the liquid injected into the reactor and due to an internal system interlock, the system may request the activation of Reactor Purge cycle to purge any excess liquid from the reactor. If necessary run “REACTOR PURGE” function in the Simulate menu.) _____ Base Pump rate for FMM20 Pump at 400 pulses should be between 3.80 ml and 4.20 ml. _____ Important Note: For the correct operation of the system, the measured Acid and Base Pump rates must be identical or similar. The maximum allowable difference in the measured volumes for acid and base injections above should not be more than 0.2ml. Sample Pump rate for WMM60 Pump at 16 pulses should be between 5.5ml and 7.5ml in ~8 seconds. (Any variation between these pumped volumes is corrected when the zero and span _____ calibration is carried out.) Replace the 100mm filter mats in fan and vent housing (see item C4 in the service kit.) Check the operation of the fan. (Note that at temperatures below 25°C, BioTector automatically switches the fan off to stabilize system temperature using its own internal heat.) Clean CO2 analyzer optics by removing the 4x M4x60 Allen bolts on the detector section. If necessary, clean both lenses, which are located on the detector and the source section of the CO2 Analyzer using the Lens Tissue (see item C5 in the service kits). Replace O-ring with the 72-0325-30 O-ring provided (see item C6 in the service kit). Oxygen Purity Test: Power up the system for at least 10 minutes before the oxygen purity test is carried out. Using the Simulate menu (see Section 8.1.2 Simulate) set the MFC (see figure 2 and table 2 in Section 4.1.1 Analysis Enclosure) flow to 10 l/h and flow oxygen gas through the CO2 analyzer for 5 minutes. At the end of this period, the CO 2 analyzer zero reading (ppm CO2) should be within ±0.5% of full scale of the CO2 analyzer range. For instance, if the CO2 analyzer range is 10000ppm, then the CO2 analyzer zero reading should be typically within ±50ppm. Go to CO2 Analyzer menu (see section 8.3.10 CO2 Analyzer) to view the CO2 Analyzer Range. _____ _____ _____ _____ (If the CO2 analyzer zero reading is outside the specifications, confirm that there is no CO 2 in the oxygen gas by connecting the CO2 filter “used with the base container” between the Cooler and CO2 analyzer inlet port and set the MFC to 10 l/h. As the size of the CO2 filter is small, keep the 10 l/h gas flow running for at least for 5 minutes and record the CO2 zero readings at the end of the 5 minute period. If the CO2 zero readings do not drop significantly with the CO 2 filter in place, this will indicate that there is no CO2 contamination in the oxygen supply.) Page 153 Warning! A Torque Screwdriver with 3mm Allen bit, calibrated to 1.5 Nm (150 Ncm), is required for the correct service of the Mixer Reactor. It is strongly recommended not to proceed with the Mixer Reactor service procedures without a torque screwdriver. An adjustable torque screwdriver can be obtained from a local supplier. Example specifications and suppliers of the torque screwdriver are as follows: Lindstrom adjustable torque driver, 40-200Ncm Stanley Supply & Services, Inc. http://www.stanleysupplyservices.com/product-detail.aspx?pn=419-704 RS Components Ltd. http://uk.rs-online.com/web/p/torque-drivers/3851794/ Loosen each bolt, located on the front of the Mixer Reactor, with small steps, moving from one bolt to another across. Remove the 4 bolts and remove the reactor motor, which contains the diaphragm, located at the back. Hold the reactor diaphragm carefully using both hands and turn the diaphragm anti-clockwise to unscrew. It is recommended to count the number of turns by putting a small mark on the diaphragm during this process. Using both hands screw in the new diaphragm (see item C7 in the service kit) and tighten it firmly. The typical minimum number of turns to tighten the diaphragm is from 7 to 8.5 turns. If a minimum number of 7 turns, or the number of turns counted above when the old diaphragm was removed, is not achieved, the diaphragm must be removed and reinstalled. Push the edge of the diaphragm down firmly into place. When the installation of the diaphragm is complete, confirm that the diaphragm forms a “concave” shape at the center. In other words, when the diaphragm is installed correctly, the diaphragm should curve in forming a dent at the center. If such dent has not formed, unscrew the diaphragm, confirm that the diaphragm is installed correctly and if necessary tighten the diaphragm more with additional turns. Confirm that the sealing face at the back of the reactor, where the diaphragm sits, is clean. Install the reactor motor back onto the Mixer Reactor and tighten each bolt by engaging the threads and stopping as soon as the threads are just engaged. Tighten each bolt, with small steps, moving from one bolt to another across. Tighten the bolts using the 3mm washers under each bolt. The torque of the screws should not exceed 1.5 Nm (150 Ncm). _____ Confirm that the temperature of the ozone destructor has dropped to ambient temperature level. Open the ozone destructor. The ozone destructor should never be opened when it is hot as the threads may seize. Confirm that the PTFE filters (discs) in the ozone destructor are clean. If there is any material build up (e.g. white powder), wash the filters using DIW (or tap water) and dry. Do not use compressed air or any gas to clean the filters. _____ Replace the catalyst and PTFE wool in the ozone destructor (see item C8 in the service kit). _____ Replace the o-ring in the Ozone Destructor (see item C6 in the service kit). _____ Reconnect power to ozone destructor heater. _____ Using the Simulate menu (see Section 8.1.2 Simulate for details) and referring to figure 1 and table 2 in Section 4.1.1 Analysis Enclosure, activate OZONE GENERATOR and confirm that the Ozone Generator is working and current displayed on screen is 0.9 Amp (±0.05 Amp). If necessary adjust the current using the Ozone Generator Current Adjustment Potentiometer located on the Ozone Generator. _____ Remove the tapes, which are used to seal the ends of the supplied CO 2 filter (see item C9 in the service kit). Replace the CO2 filter on the Base reagent container. Seal the Base container tightly. _____ Isolate the air supply to the analyzer. Go to Simulate menu and set MFC to 60 l/h and run the oxygen supply until the flow drops to 0 l/h (until the oxygen tank is empty). Install the new Hepa Filter (see item C10 in the service kit) carefully without contaminating the open tubing. Turn the air supply on. _____ Page 154 Check the air supply pressure. The set point pressure should be 1.5 bar (BioTector compressor 1.2 bar). When the oxygen concentrator is running, the pressure typically cycles from 1.5 bar to 0.9 bar. Check the O2 PRESSURE SENSOR reading looking at the O2Controller Status menu. The pressure should be 400 mbar (±10 mbar) at 20 l/h MFC flow. See Section 8.1.6 Oxygen Controller Status for details. _____ Using the Simulate menu (see Section 8.1.2 Simulate for details), check the operation of the Mass Flow Controller (MFC) and confirm that the MFC is working at various flow set points. _____ Check the BioTector for any gas/liquid leaks by running the PRESSURE TEST cycle using the Process Test menu (see Section 8.1.1.1 Pressure Test for details). Check the gas flow in the system by running the EXHAUST TEST and SAMPLE OUT TEST in Process Test, Flow Test menu (see Section 8.1.1.2 Flow Test for details). _____ Confirm all signals (4-20mA and volt free contacts) are signaling correctly to the external control device. _____ If necessary, go to Operation, Time & Date menu and adjust the time and the date. When the system service is completed, go to Diagnostics, Service menu and select RESET SERVICE COUNTER function (see Section 8.1.7 Service for details). _____ Carry out an “Install New Reagents” cycle using the Install New Reagents menu (see Section 2.2.2.1 Install New Reagents for details). Confirm that the zero readings obtained during the Zero Calibration cycle are stable. (If the reagent lines do not fill during the Install New Reagents cycle, stop the BioTector to prime the pumps manually. Remove the dip tubes from the reagent containers, and seal the containers. Place the dip tubes into a small container containing DIW. If DIW is not available use tap water. Raise the container above the height of the BioTector. Go to Zero Calibration menu and select RUN REAGENTS PURGE function to prime the pumps. Once the pumps have been primed, reinstall the dip tubes into the reagent containers and repeat the Install New Reagents cycle.) When the Mixer Reactor is serviced, there is a possibility of contamination, which may create an unacceptable TOC offset. If the TOC readings obtained during the zero calibration cycle are higher than expected, a service zero calibration cycle can be initiated using the SET SERVICE ZERO function in Service menu, while the BioTector is running. When initiated, BioTector automatically runs a total of 5 zero calibration cycles during the following 100 online measurements and automatically adjusts the zero offset values to compensate for the removal of the contamination. It will therefore not be necessary to revisit the BioTector after the service or to repeat the zero calibration cycle. See Section 8.1.7 Service for further details. Program the concentration of the standard solution in the Span Calibration menu (2.3.2 Span Calibration). The concentration of the calibration standard used must be typically greater than 50% of the full scale of the RANGE the calibration is carried out. In order to see BioTector calibrated ranges, see System Range Data screen (2.2.3 System Range Data Screen). (To prepare a standard solution, see procedures described in Section 6.2 Calibration _____ _____ _____ Standards or information sheet “R009. Standard Solutions for BioTector Multi-component Analyzer”, which is available inside the MMC/SD card shipped with the BioTector.) Connect the standard solution to the MANUAL/CALIBRATION port. If these ports are not available, use the SAMPLE 1 port. It is recommended that the standard solution is located at the same height as the sample chamber. The tubing length between the standard solution and the BioTector MANUAL/CALIBRATION port should be between 2 and 2.5 meters. Run the Span Calibration cycle using the RUN SPAN CALIBRATION function in Span Calibration menu. A minimum of five complete analysis cycles is recommended for the span calibration. Span Calibration cycle should be carried out only when stable zero readings are obtained after a Zero Calibration cycle completed without any warnings. ( In systems using multiple _____ operation ranges, it is recommended to carry out a Span Check cycle at the other operation ranges used and if necessary to adjust the span factor manually using the Span Calibration menu.)
