7 USED TERMS AND SIGNAL INDICATIONS DANGER! This means that death, severe physical injuries and/or important material damages will occur in case the respective safety measures are not fulfilled. WARNING! This means that death, severe physical injuries and/or important material damages may occur in case the respective safety measures are not fulfilled. This means that minor physical injuries may occur in case the respective safety measures are not fulfilled.
8 INTRODUCTION The patented M&C ECM-ExII gas cooler unit is always to be installed in situations where there is interference from moisture in the gas to be measured. Reduction of the gas temperature inside the cooler to a stable and very low dew point effects a condensing-out of the sample gas. 8.1 SERIAL NUMBER The type plate with the serial number is located at the side panel of the cooler housing (wall mounting version).
The gas to be measured is taken from the ECM-ExII gas cooler by a gas sample probe via a heated sample line and cooled down to a dew point of +5°C. The super-fine filter located afterwards removes solid particles. For increased operating safety of the entire system we recommend installing a super-fine filter with a liquid alarm sensor. If required an aerosol filter can be installed in front of the flow meter . The gas thus treated can now be passed into the analyser .

The cooler ECM-ExII is equally suitable for wall installation. The depth of the housing of the cooler is 270mm (316mm with optional mounted peristaltic pumps ). WARNING! The cooler ECM-ExII corresponds to the system protection IP20 (EN 60529) and therefore suitable for use in clean and dry rooms. Solids and water must be avoided to enter the cooler housing via the ventilation outlet. For installation according to NEC article 501.

14 INSTALLATION INSTRUCTIONS The ECM-ExII cooler is suitable for wall mounting. NOTE! The cooler is only suitable for dry and clean rooms (IP20). The operating position for this cooler is exclusively vertical. This is the only way to ensure proper separation and removal of condensate in the heat exchangers.
NOTE! Do not mix up the hose connections; the inlet and outlet connections of the heat exchangers are marked with arrows; Ensure that the connections are sealed adequately; To ensure free removal of the condensate, ensure that the listed diameters for the condensate removal lines are not reduced! Ensure that the connections are sealed adequately by noting the following: Borosilicate glass heat exchangers with connections GL18-6 respectively GL25-12 (standard) Before assembly, check the GL coupling
15.2 ELECTRICAL CONNECTIONS CARE! When connecting the equipment, please ensure that the supply voltage is identical with the information provided on the model type plate! WARNING! NOTE! WARNING! Do not work at alive parts unless the area is known to be nonhazardous. Attention must be paid to the requirements of IEC 364 (DIN VDE 0100) when setting high-power electrical units with nominal voltages of up to 1000V, together with the associated standards and stipulations.
Figure 5 Electrical sockets alarm contact The connection of the mains respectively status alarm signals happens as follows: 16 release the screws (7 pcs.) from the cooler top and remove it; put the cables (6-12mm) through one of the cable glands and connect them according to a.m. wiring plan; the re-installation of the cooler top happens in the opposite way. START-UP The thermo-hydraulic controlled cooling system of the ECMExII permit automatic start-up of the cooler.
17 CLOSING DOWN NOTE! CARE! 18 The location for the cooler must remain frost-free, even when the unit has been switched off! If the cooler unit is putting out of action for a short time no particular measures need to be taken. We recommend sweeping the cooler with inert gas or ambient air while the unit is putting out of action for a longer time. Aggressive condensate is possible.
Replace the heat exchangers as follows: Dry and clean the push-in opening in the aluminium cooling block with a cloth; Smear the push-in opening with a thin and equal layer of thermal conductivity paste (part no. 90K0115); Smear the heat exchangers with a thin and equal layer over the whole surface with thermal conductivity paste (part no. 90K0115) to ensure good conduction of heat.
18.3 MAINTENANCE OF THE OPTIONAL MOUNTED PERISTALTIC PUMP(S), TYPE SR25.2 Before the maintenance work is carried out, it is necessary hat the specific safety procedures pertaining to the system and operational process are observed! DANGER Dangerous voltage! It is necessary to take the pump off the mains before any assembly, maintenance and repair work is carried out! Flexible tube, conveying belt, contact pulleys and contact springs are the only parts of the pump subject to wear.
Take away conveying belt and remove the old hose set from the guides by the hose connectors; Press the two contact pulleys and check whether the spring pressure is still sufficient, if not, the contact springs have to be changed; Put the new hose set with the hose connectors into the guides of the conveying belt ; NOTE! Only the usage of the original hose set guarantees a perfect function. Never lubricate the hose.
19 OPERATING OF THE BUILT-IN ELECTRONIC TEMPERATURE CONTROLLER Only use temperature controller 01 B 8365. NOTE! In normal operation the display of the temperature controller shows the actual cooling temperature. Figure 7 shows the front view of the temperature controller. Figure 7 Front view of the temperature controller 19.1 CHANGING THE SET VALUE To change the set value the P-key has to be pushed < 2 sec. The company fixed value of 5°C appears. With the two arrow keys the value can be changed.
20 TROUBLE SHOOTING The following table should give an overview of possible errors and an instruction to check and to repair them (is not valid for the starting-up period of cooler).
