"# $"%&'() * 63 of 137 Statement Subject: Gas Detection Cabinet “GDCAB” To whom it may concern GDCAB temperature rating: The temperature rating for our gas detection cabinet is the following: Ambient temperature: 15 to 40 °C Media (sample) temperature: 15 to 60 °C Salwico GD True IR “Band B” (P/N 5200204-03A): It has been shown for some applications (e.g. crank case vent) that the gas detectors in our gas detection cabinet provide biased %LEL values due to the remaining oil mist not totally filtered by the coalescing/oil filter. As a consequence false alarms might arise and cause unnecessary engine trips. Consilium is now investigating an alternative for solving this problem consisting in the replacement of our standard Salwico GD True IR (P/N 5200204-01A) with a Salwico GD True IR “Band B” (P/N 5200204-03A). Each gas detector gives a good response to a wide range of Hydrocarbon Gases and Vapours. In order for the detector to give a linear output with a particular gas or vapour the sensor must first be configured with the corresponding software linearisation table. Each linearisation table is originally created by exposure of a sensor to a range of the vapour concentrations. The Band B detector includes therefore a linearisation table corresponding to a more appropriate gas range than a standard Salwico GD True IR for the applications mentioned above. It is the reason why these gas detectors need a correction factor “cross-sensitivity” when calibrated with Methane gas. While more information will be provided when this solution is proven valid, here comes an extract of a linearization table for a Band B detector: Relative Cross-sensitivities for Gases & Vapours Currently Available for Salwico GD True IR “Band B” Gas concentration 20%LEL 50%LEL Methane 0,7 0,6 Ethane 1, 1,7 Propane 1,8 1,5 Butane 1,5 1,4 Ethene 0,3 0,3 Propene 0,6 0,7 As an example, the Band B detector is expected to provide 50%LEL*0,6 = 30%LEL when exposed to 50%LEL Methane. Hence the factor applied when calibrating the detector with Methane.

We strongly recommend protecting the gas detector sensor cell when doing painting work to avoid the high amount of silicones that exists in paint. In order to protect the sensor cell Consilium has installed a protection cover that is mounted on the detector cell from delivery. Keep the covers mounted as long as possible, recommendable is to keep them on until first sea-trial. It’s also a benefit to keep the gas detectors without power. When the gas detector is not energized it’s less affected by paint. x To help maintain the correct IP class, plug any unused cable glands entries. x Keep the detectors protection caps on as long as possible. The protection caps should be removed after commissioning is completed and the system is handed over. 1.2 Location of sensors Considerable guidance is available from standards such as IGC Code 13.6.2 Guide for selection, installation, use and maintenance of apparatus for the detection and measurement of combustible gases or Oxygen. Similar international codes of practice may be used where applicable. In addition certain regulatory bodies publish specifications giving minimum gas detection requirements for specific applications. These references are useful, but tend to be either very generic and therefore too general in detail, or application specific and therefore irrelevant in most applications. The placement of detectors should be determined following the advice of experts having specialist knowledge of gas dispersion and equipment involved. The agreement reached on the location of detectors should also be recorded. There are a number of simple and quite often obvious considerations that help to determine detector location: x The position shall be with due regards to the density of the gas the detector is intended for (refer to IGC Code 13.6.2.). x The area in which the detector may be mounted must be in accordance with the class rules and IGC Code 13.6.7. The number of sensors recommended depends on room size, shape, airflow and so on. x The prevailing air currents around the sensing head should possess the maximum amount of gas, to attain a maximum effect. 2|P a g e 80 of 137 x The detector should be mounted where gas leakage is most likely to occur. All possible leakage points like flanges, joints, pumps, etc. should be identified as such an monitored. x Compare actual environmental specifications and regulations with the technical specifications of the used detector. x The gas detector should be installed in an area free from shocks or vibrations. x Ensure the proposed site will not interfere with movement of existing equipment, e.g. cranes, doors etc. x Avoid mounting the gas detector where it may be subjected to sudden transients in ambient temperature (e.g. above heater/radiator). x To detect gases that are lighter than air (e.g. Methane and Ammonia), detectors should be mounted at high level and preferably use a collecting cone. x To detect heavier than air gases (e.g. Butane, Sulphur Dioxide and Propane), detectors should be mounted at a low level. x O2 detectors should preferably be mounted at head height x Consider how escaping gas may behave due to natural or forced air currents. Mount detectors in ventilation ducts if appropriate. x Detectors should be positioned a little way back form high pressure parts to allow gas clouds to form. Otherwise any leak of gas is likely to pass by in a high speed jet and not be detected. x Consider ease of access for functional testing and servicing. 1.3 IR detectors There are two main types of IR Detectors, open-path or single point. Open-path detectors are mainly used in outdoor situations and Single point detectors in indoor situations. Many combustible gases have absorption bands in the infrared region of the electromagnetic spectrum of light and the principle of infrared absorption is used to detect the gas concentration. IR Detectors has a very fast response (typically less than 10 seconds). They can also be designed to be unaffected by any known ‘poisons’, they are failsafe and they will operate successfully in inert atmospheres, and under a wide range of ambient temperature, pressure and humidity conditions. The technique operates on the principle of dual wavelength IR absorption, whereby light passes through the sample mixture at two wavelengths, one of which is set at the absorption peak of the gas to be detected, whilst the other is not. A detector 3|P a g e 81 of 137 compares the signal strengths of sample and reference beams and, by subtraction, can give a measure of the gas concentration. x Presence of oxygen is not required during equipment life time. x Immunity to poisoning from H2S, silicone and other agents. x No saturation effects from high gas concentrations. x The gas flow rate has no influence on accuracy. x Proven high reliability and long term stability results in low test frequency and lower calibration cost. 1.4 Catalytic detectors Catalytic sensors consist of a very small sensing element sometimes called a "bead". It is made of an electrically heated platinum wire coil, covered first with a ceramic base such as Alumina and then with a final outer coating of Palladium or Rhodium catalyst dispersed in a substrate of Thoria. This type of sensor operates on the principle that when a combustible gas/air mixture passes over the hot catalyst surface, combustion occurs and the heat evolved increases the temperature of the "bead". This in turn alters the resistance of the platinum coil and can be measured by using the coil as a temperature thermometer in a standard electrical bridge circuit. The resistance change is then directly related to the gas concentration in the surrounding atmosphere and can be displayed on an indicating device. The response time for catalytic sensors is typically between 20 and 30 seconds. These detectors have the following properties: x Sensitive to poisoning from H2S, silicone and other agents. x Can detect almost all hydro carbon based gases 1.5 Electrochemical detectors There are many different designs of electrochemical detectors but the common features are described below: Three active gas diffusion electrodes are immersed in a common electrolyte for efficient conduction of ions between the working and counter electrodes. Depending on the specific cell the target gas is either oxidized or reduced at the surface of the working electrode. This reaction alters the potential of the working electrode relative to the reference electrode. The primary function of the associated electronic driver circuit connected to the cell is to minimize this potential difference by passing current between the working and counter electrodes, the measured current being proportional to the target gas concentration. Gas enters the cell through an external diffusion barrier that is porous to gas but impermeable to liquid. 4|P a g e 82 of 137 Gas specific electrochemical sensors can be used to detect the majority of common toxic gases, including CO, H2S, Cl2, O2, SO2 etc. Electrochemical sensors are compact, require very little power, have excellent linearity and repeatability and generally have a long life span, typically one to three years. Response times are typically 30-60 seconds. 5|P a g e 83 of 137 PUMP AND DETECTOR CABINET The pump and detector cabinet should be installed not less than 3 meters above the sample point in order to avoid air locks in the pipes. For installation and for the future service work, there must be enough space, approx. 0.5m, at the pipe connection side, normally the left side. There are removable plates or cable glands intended for the installation of cable inlets on the underside of the cabinet, for electrical connections. The electrical connections are made in accordance with the project drawings supplied with system. Sampling pipe & Exhaust Pipe Very important! The sample and exhaust pipe from the pump and detector cabinet is connected via a nipple at the intended site and must be mounted with a slope towards the measuring/ exhaust point. This extremely important for the exhaust pipe! The below picture shows a correct installation where the pipes are installed in such a way that problems with air locks and pressure build-up will be avoided. Pump and Detector Cabinet installation recommendation Page 1 84 of 137 Below picture showing an installation where the pipes have been installed in the wrong way. It is very important that the pipes are not installed in this manner; the functionality of the system may be greatly reduced due to the height and pressure difference (pressure build-ups). Moisture and debris will be pushed inside the pumps and detectors through the inlet and will accumulate because it cannot exit through the exhaust.

FILTER PLACEMENT U U U U V PIPE CONNECTIONS Suction Pipes The sampling pipes are connected to the pre-mounted and numbered stainless steel connection nipples on the side of the cabinet. NB! These nipples should be tightened with a spanner, 1.25 turn only, from the hand-tightening stop. If dismounted the nipple should be retightened to exactly the same position during remounting. Also note that the pipes should be installed in such a way that service can be performed on an individual sampling point without unnecessary dismounting of other pipes. Pump and Detector Cabinet installation recommendation Page 3 86 of 137 BENDING OF SAMPLING PIPES In order to avoid unnecessary air resistance in the sampling pipes and risk of deformation and the formation of fractures, a minimum bending radius of approx. 150 mm is recommended. PIPE SYSTEM The pipe system transports the test samples from the sampling points to the pump and detector cabinet. When the sampling pipes are installed, care should always be taken that the pipes are installed in such a way that the risk of air locks is avoided. All pipe couplings with conical seals forming part of the pipe system should always be sealed with Loctite 577. (NB! Not thread tape). PIPE SUSPENSION Suspension of the pipe assembly or individual pipes should be made in such a way that the U X U X in such a way that vibrations or other similar actions do not damage them. When installing the pipes, care should be taken not to allow them to become deformed. PIPE COUPLINGS Efforts should be made to ensure that as few pipe couplings as possible are used for each sampling pipe. This will avoid unnecessary air resistance in the pipes, caused by turbulence due to unevenness of the joints, and also to reduce the possibility of leakage to a minimum. When a pipe cut is necessary, make sure that the pipe is not deformed at the cut and that the Y % U V Y Each manufacturer’s individual recommendations on tightening should be observed when installing those pipe couplings that must be used.

The manual shut-off valves shall remain open during normal operation and when there is water in the Water Ballast Tanks. This will keep the Counter-pressure-air flow and avoid water entering the pipes. Water in ballast tanks: Before ballasting, the corresponding Sampling-points (SP) must be disconnected from the sampling sequence at the SW2020 Control Unit. This will avoid water being sucked into the pipes and damaging the system. Follow the instructions: - Press ”List-Sampling points” - Press Arrow-keys to find a single SP or a whole group of SPs for action - Press ”Disconnect” - Press ”Disconnect” again to confirm Continue until all SPs corresponding to ballast tanks are disconnected. All disconnected points are listed in the disconnections list. - Press ”List Disconnections” to see the disconnected SPs. When the ballast tanks are empty, the SPs shall be reconnected. - Press ”Reconnect” in the “List Disconnections” or in the ”List Sampling Points”. The user will be asked if he wants to automatically purge all SPs in a group or a single SP. We recommend choosing - “Yes”. Note! If you have a ”Flow-fault” on a SP, this might, besides the indication of a clogged pipe or on-line-filter, also indicate water in the tank. Disconnect the SP immediately and find the cause. Alarm levels: See this manual chapter 3 Gas alarm. There are two alarm levels in the SW2020; Low “LO” and High “HI”. The default settings for the most common gases are: - Propane: 5% L.E.L., for Low alarm and 10% L.E.L., for High alarm. - Oxygen: 19% for Low alarm and 17% for High alarm. - Hydrogen Sulphide: 5ppm for Low alarm and 10 ppm for High alarm. For other gases the alarm levels should be set according to requirements in rules. Fault Alarms: See this manual chapter 3 Fault alarm. C27 105 of 137 '45 + ! ! , *- % . /% * % , * !

INSTALLATION B1 119 of 137 Salwico SW2020 Installation 2.1 CONTROL UNIT DETECTOR The control unit is the man-machine interface and controls the electronics in the analysing unit. It consist of a LCD clear text Display, LED Display, LED's, keyboard, microprocessor and memory for the software, definitions, additional texts etc. The unit is normally made for wall mounting and should be placed in a well visible position e.g. cargo control room. Electrical connection terminals to the analysing unit, the repeater unit and the optional printer are placed in the bottom of the control unit cabinet. As an alternative both the control unit and the analysing unit can be delivered in one single cabinet. The SW2020 control unit is divided into two parts; the gas alarm panel and the operating panel. The gas alarm panel is activated when a gas alarm situation is detected in the system. The sampling point number, alarm level (LO or HI) and the actual gas detector in alarm are displayed. There are three keys on the operating panel. The Alarm Mute key is used to acknowledge the gas alarm and the Alarm Reset key is used to reset the gas alarm. The third key Alarms in Queue is used to toggle the sampling points in alarm. The Operating Panel continuously shows, in the clear text display, sampling point and the last measured value. The Fault LED is lit and a fault message is shown in the clear text display when a fault alarm is generated. The List and Setup keys are used to manage the gas sampling system. The numeric key pad is among other things used for value settings and clear text setup. B2 120 of 137 Salwico SW2020 Installation 2.2 ANALYSING UNIT The analysing unit contains all functions for detection and transport of the test samples. Its components comprise:gas detectors, solenoid valves, sampling and transport pump, flame traps, flow meter, remote I/O - PCB-boards, power supply unit and terminals for power supply, alarm outputs connection to the control unit and repeater unit as well as connections for all piping included in the system. The analysing unit should be installed not less than 3 metres above the main deck in order to avoid air locks in the pipes and ensure the correct work of the automatic flow watching function. The area should be ventilated and temperature-controlled. For installation and for the future service work, there must be enough space, approx. 0.5m, at the pipe connection side. Normally the left side. There are removable plates intended for the installation of cable inlets on the underside of the cabinet, for electrical connections. Exhaust Pipe The exhaust pipe from the analysing cabinet is connected via a nipple at the intended site and should be mounted with a slope towards the exhaust point. Refer to page B4. Fresh Air Pipe The fresh air pipe to the analysing cabinet should be connected via a nipple at the intended site. The air inlet can open up directly into the room where the analyzing unit is installed, provided that the atmosphere in the room is clean and temperature controlled. Otherwise a pipe leading to such a space must be installed. Refer to page B4. Calibration Gas Pipe The calibration gas pipe from the calibration gas cylinder, with a relief valve and pressure gauge, is connected to the analysing cabinet via a nipple at the intended site. Refer to page B4. The pipe should be mounted in such a way that replacement of the calibration gas cylinder can be made without unnecessary strain on pipes and couplings. The electrical connections are made in accordance with the electrical drawing in this chapter. Instrument air 5 - 16 kp/cm2 inlet The inlet pipe for dry instrument air is connected to the analysing unit via a nipple at intended site. Refer to page B4. 2.2.1 Pipe Connections 2.2.2 Calibration Gas Cylinder Suction Pipes The calibration gas cylinder is mounted next to the analysing cabinet and fixed in the conventional manner for pressure vessels. The gas cylinder can alternatively be mounted inside the cabinet. The sampling pipes from the manual shut-off valves are connected to the premounted and numbered flame trap on the side of the analysing unit by means of the stainless steel connection nipples on the flame traps. NB! These nipples should be tightened with a spanner, 1.25 turn only, from the hand tightening stop. If dismounted the nipple should be retightened to exactly the same position during re-mounting. The pipes between the analysing unit and the normal shutoff valves should be mounted in such a way that air locks do not occur. Also note that the pipes should be installed in such a way that service can be performed on an individual flame trap as well as on On-Line Filters without unnecessary dismounting of other pipes.

The unit is designed for wall or panel mounting and should first of all be placed on the bridge in a well visible and easily accessible location. The LCD-display indicates in clear text the sampling point(s) in alarm, alarm level(s) and fault messages. B5 123 of 137 Salwico SW2020 Installation 2.4 PIPE SYSTEM The pipe system transports the test samples from the sampling points to the analysing unit. In addition to the piping, the system includes: shut-off valves, flame traps, pipe couplings, sleeves, filters and pipe terminations. When the sampling pipes are installed, care should always be taken that the pipes are installed in such a way that the risk of air locks is avoided. There are two main ways of installing the piping from the analysing unit to the various sampling points; either the pipes are installed above deck or through the pipe tunnel, or a combination of both methods. Note that pipes installed above deck must be protected against mechanical damage. Refer to drawing on page B7 of this manual. All pipe couplings with conical seals forming part of the pipe system should always be sealed with Loctite 577. (NB! Not thread tape). 2.4.1 Pipe Suspension Suspension of the pipe assembly or individual pipes should be made in such a way that the distance between the suspension points does not exceed 1 metre. The pipes should also be fixed in such a way that vibrations or other similar actions do not damage them. When installing the pipes, care should be taken not to allow them to become deformed. 2.4.4 Bending of Sampling Pipes In order to avoid unnecessary air resistance in the sampling pipes and risk of deformation and the formation of fractures, a minimum bending radius of approx. 150 mm is recommended. Refer to separate instructions for installation of other components of the pipe system. - Flame Trap (analyzing unit) - Manual shut-off valves - Chapter 2.5 - Chapter 2.6 2.4.5 Pipe installation check NB. 1. Before connection of the sampling pipes to the Analysing Unit and to the On-Line-Filters: Always flush the pipes with compressed air in order to clean them from dust and water. After cleaning, finish the complete connection between the Analysing Unit, Shut Off Valves, On Line Filters and Pipe end Accessories. NB. 2. A test has to be performed on every sampling pipe, to verify that there are no leakages. Also verify that each sampling point is correctly connected to the Analysing Unit. It is possible to do a test of the air tightness by disconnecting the tubes one by one inside of the cabinet and perform the test by connecting a manometer, shut-off valve and compressed air. The drawing on page B16 of this manual shows a proposed method of suspension and fixing. 2.4.2 Sleeves and Bulkhead Passages Some type of passage arrangement must be used when passing through deck or bulkhead plates. Such proposed units are shown on drawings on page B15 and B16 of this manual. 2.4.3 Pipe Couplings Efforts should be made to ensure that as few pipe couplings as possible are used for each sampling pipe. This to avoid unnecessary air resistance in the pipes caused by turbulence due to uneveness of the joints, and also to reduce the possibility of leakage to a minimum. When a pipe cut is necessary, make sure that the pipe is not deformed at the cut and that the air flow resistance is not increased. Also note that capillary connections has to be carefully soldered to avoid unnecessary air flow resistance. Each manufacturer’s individual recommendations on tightening should be observed when installing those pipe couplings that must be used. B6 124 of 137 Salwico SW2020 Installation 2.5 FLAME TRAPS The flame traps are normally supplied fitted to the analysing unit. Refer to the installation instructions for the analysing unit in Chapter 2.2.1 for pipe connection instructions. NB! The flame trap must be of an approved type.

CAL.GAS GAS CABLE INLET B8 125 of 137 Salwico SW2020 Installation 2.6 MANUAL SHUT-OFF VALVES The task of the manual shut-off valves is, where necessary, to shut off the pipe system in an explosion risk zone from the system in a safe zone. This may occur when a certain sampling area has a temporary high gas concentration or is filled with inert gas. The shut-off valves should also be used for service needs, such as replacement of flame traps, or if a certain sampling pipe is disconnected from the analysing unit. When there is no compressed air in the counter pressure system combined with water in the ballast tanks, a closing of the shut-off-valves is recommended to avoid water and dirt inside the sampling pipes.Notice that as long as there is compressed air to serve the counter pressure system in water filled ballast tanks, the shut off valves shall remain open. Installation of the valves shall be made in the wall between the safe and explosive zones. Holes are cut for the insertion of welding sleeves with an internal thread, the shut-off valve then being screwed on from inside a safe zone by means of taper thread couplings supplied and sealed with ”Loctite 577”. NB! All valves should be marked with the number of the corresponding sampling point. It is important that the mutual distance between the valves is taken into consideration, and that the sampling pipes from the analysing unit are installed in such a way that any service on an individual shut-off valve can be carried out without any unnecessary dismounting of other pipes.

Two types of filters have been developed for this purpose. One type for mounting on the pipe, ”On-line filter”, and a second for mounting at the end of the sampling pipe at the sampling point, ”End-line filter”. On-Line Filter This filter is used for such sampling pipes where end-line filters cannot be used for a variety of reasons, such as areas which may be termporarily water-filled or where access is for other reasons, so difficult that necessary filter replacement may be impaired or neglected. Installation of on-line filters must be done in such a manner that the filter is easily accessible for replacement, without causing unnecessary strain on pipes and connections. The online filter should always be placed as close to the sampling point as is practically feasible. But never in a safe zone. The nipples should be tightened in accordance with pipe connections chapter 2.2.1. We recommend that each individual filter should be marked with its corresponding sampling point number.

In filter installation, e.g. end-line filter, the height above the bottom should be taken into consideration with respect to this. In certain areas care must be taken to prevent oil or water from being sucked into the sampling pipes, and in such cases a height above the bottom of 0,5 m or more can be allowed. Corners, where the air circulation is low, should be avoided. Note that the last 0,2 m of the pipe termination end must point downwards. Each pipe termination should be marked with the corresponding sampling point number. Option Refer to Chapter 2.7 for special pipe termination facility. 2.8.2 Location of the Sampling Points In accordance with the regulations and draft proposals that have been drawn up by the classification societies, the following areas are to be monitored by the permanently installed gas sampling system: • • • • • Cofferdams Pipe tunnels Ballast tanks and double bottoms Other empty areas adjacent to slop tanks Pump rooms, connected to a separate system. In addition, it can be recommended that stool tanks and other empty areas adjacent to the cargo tanks are connected to the permanently installed gas sampling system. In accordance with these rules it is essential that the planned number of sampling points and their location including the pipe installation should be evaluated and commented on by the classification societies prior to installation. 2.8.3 Marking of Sampling Points Each sampling pipe must be marked with its number at the sampling point as well as the manual shut-off valve. (Each sampling point is numbered at the flame trap on the analysing unit.) Salwico SW2020 always has one sampling point reserved for internal monitoring of the analyzing cabinet, normally the last sampling point. B12 128 of 137 Salwico SW2020 Installation 2.9 OPTIONS 2.9.1 Counter pressure System The counter pressure system is to be used for such sampling points which are located in areas that can be temporarily filled with water. The counter pressure system, when supplied, is built into the Salwico SW2020 system.The operation of the counter pressure system is based on compressed air being automatically connected to sampling points, during the not sampling periode and when the sampling point is temporarily disconnected from the automatic scanning. Note! The hand maneuvered shut off valve in the bulkhead passage shall remain in open position when the sampling point is disconnected via the control panel. Only in case of loss of the supply of compressed air or when the pipes by some reason are mechanically disconnected between the analysing unit and the bulkhead, the shut off valves for safety reasons shall be closed. Counter pressure system installation requires connection of compressed dry instrument air to the analysing unit. Incoming operating pressure: 5 - 16 kp/cm 2. Pressure regulator set to 3.2 kp/cm 2. Max air consumption: approx. 10 - 20 litres/hour for each sampling point . For cone connection refer to installation of cone in this chapter. 2.9.2 Pipe Cleaning System A pipe cleaning system is recommended for blowing the pipes clear of water. The pipe cleaning system, when supplied, is built into the Salwico SW2020 system. Its installation requires connection of compressed dry instrument air to the analysing unit. Incoming operating pressure: 5 - 16 kp/cm 2. Pressure regulator set to 3.2 kp/cm 2. Note! When both a pipe cleaning and a counter pressure system are included in the SW2020 the same compressed air connection is used jointly .

The manual shut-off valves shall remain open during normal operation and when there is water in the Water Ballast Tanks. This will keep the Counter-pressure-air flow and avoid water entering the pipes. Water in ballast tanks: Before ballasting, the corresponding Sampling-points (SP) must be disconnected from the sampling sequence at the SW2020 Control Unit. This will avoid water being sucked into the pipes and damaging the system. Follow the instructions: - Press ”List-Sampling points” - Press Arrow-keys to find a single SP or a whole group of SPs for action - Press ”Disconnect” - Press ”Disconnect” again to confirm Continue until all SPs corresponding to ballast tanks are disconnected. All disconnected points are listed in the disconnections list. - Press ”List Disconnections” to see the disconnected SPs. When the ballast tanks are empty, the SPs shall be reconnected. - Press ”Reconnect” in the “List Disconnections” or in the ”List Sampling Points”. The user will be asked if he wants to automatically purge all SPs in a group or a single SP. We recommend choosing - “Yes”. Note! If you have a ”Flow-fault” on a SP, this might, besides the indication of a clogged pipe or on-line-filter, also indicate water in the tank. Disconnect the SP immediately and find the cause. Alarm levels: See this manual chapter 3 Gas alarm. There are two alarm levels in the SW2020; Low “LO” and High “HI”. The default settings for the most common gases are: - Propane: 5% L.E.L., for Low alarm and 10% L.E.L., for High alarm. - Oxygen: 19% for Low alarm and 17% for High alarm. - Hydrogen Sulphide: 5ppm for Low alarm and 10 ppm for High alarm. For other gases the alarm levels should be set according to requirements in rules. Fault Alarms: See this manual chapter 3 Fault alarm. C27 136 of 137 Salwico SW2020 Technical Data 4.6 Vacuum Pump The vacuum pump 107 CCD20 used in the SW2020 Gas Sampling System is a membrane pump designed for a high degree of efficiency when it is used for vacuum. It is designed for continuous operation with permanently lubricated bearings, a long life Buna “N” diaphragm, stainless steel valves and aluminum valve plate. The pump is balanced for low vibration operation and in addition mounted on shock absorbers. The diagram for calculation of sampling time previous in this manual is a result from real tests on vacuum pump 107 CCD20, with sampling pipes of inner diameter 6 mm. The flow meter and the flow switch monitor the flow capacity of the pump. The system vacuum guard or the flow switch supervises the tightness of the pump membrane. DATA: Model: Motor voltage/frequency Power Current Flow at free flow Flow at –0.2 Bar (vacuum) Flow at –0.4 Bar (vacuum) Thomas 107 CCD20 220/50-230/60 130 Watt 1,0 Amp 19 L/min 14 L/min 9 L/min MAINTENANCE: Below procedures refer to the drawing and part list found on the next page. The maintenance of the pump is mainly to exchange diaphragm and valve flappers after they have been worn-out. By removing of the pump head with the four screws (item 13), this service is easily accessible. Exchange the diaphragm (item 3) by removing the diaphragm hold down plate (item 5) with the four screws (item 4). Exchange or cleaning of the valve flappers: Remove the valve plate (item 24). Unscrew the valve flapper screw and remove the valve flappers (item 20), one on each side of the valve plate. Be careful not do damage or contaminate the surface where the flappers are working. Clean the flappers and the surface carefully with alcohol and then blow dry. Make sure that the flappers are pressing tight towards the valve plate, otherwise the capacity of the pump will be reduced. Our Spare part set for the pump Art. No. 7360, contains diaphragm, valve flappers and valve plate gasket (item 3, 20 and 23). D18 Salwico SW2020 Technical Data 137 of 137 D19
