Page 9: Introduction
INTRODUCTION The M&C cooler ECM is used for applications where interfering moisture loading in the sample gas is to be expected. By lowering to a very low stable dew point, condensation is prevented in the analyzer and a fluctuating measurement value due to water vapour cross sensitivities or volumetric errors is avoided. SERIAL NUMBER The type plate with the serial number is located on the right side of the cooler housing (wall-mount). -

Page 13: Function
The cooler ECM is equally suitable for wall installation. The depth of the housing of the cooler is 270 mm [≈ 10.6"] (316 mm [≈ 12.4"] with optional mounted peristaltic pumps). On the upper side of the cooler housing you will see the cut outs for 1 or 2 heat exchangers. Sample gas enters and leaves the heat exchangers by the correspondingly connections on the upper part of the heat exchangers (see chapter 8. -
Page 14: Reception And Storage
Sample Sample Cooling block +5 °C [41 °F] Condensate OUT Figure 4 Schematic diagram of the heat exchanger function RECEPTION AND STORAGE The ECM gas cooler is a complete pre-installed unit. Carefully inspect the ECM and any special accessories included with it immediately on arrival by removing them from the packing and checking for missing articles against the packing list! Check the items for any damage in transit and, if required, inform the shipping insurance company immediately of the damage found! The cooler must be stored in a weather protected frost-free area! -
Page 15: Installation Instructions
INSTALLATION INSTRUCTIONS The ECM cooler is suitable for wall mounting. 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. During transport and installation, the cooler must always be stood up with the transport feet positioned Note underneath so that the oil in the closed compressor circuit cannot run out of the compressor case. - Page 16 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; Note 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)

Page 17: Electrical Connections
ELECTRICAL CONNECTIONS Incorrect mains voltage can destroy the device: When connecting the device, make sure that the mains voltage is correct as specified on the type plate! Caution 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 1000 V, together with the associated standards and stipulations. -
Page 18: Preparations For Commissioning
Use the following procedure to connect the mains line and the signal lines: 1. Loosen the screws (7 pieces) of the cooler top and remove the cooler top. Pull the cable through the two cable glands with a clamping range of 6-12 mm in the bottom of the cooler. Connect the mains cable (3 x 1 mm²/AWG 17) to X1 according to the wiring diagram. -
Page 19: Closing Down
CLOSING DOWN 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 Note 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. -
Page 20: Maintenance
MAINTENANCE The safety instructions specific to the plant and process are to be consulted prior to any maintenance work! Dangerous voltage! It is necessary to take the gas cooler off the mains before any assembly, maintenance Danger and repair work is carried out! The ECM cooler does not require any special maintenance intervals. -
Page 21: Cleaning The Fins Of The Condenser
18.2 CLEANING THE FINS OF THE CONDENSER Dust on the fins of the condenser reduces the cooling capacity. Therefore it is necessary to clean the fins from time to time. The following steps are recommended: 1. Shut off the gas flow; 2. -
Page 22: Mounting Instructions For Sr25.2 Peristaltic Pump (Optional)
Peristaltic pump is under pressure! Do not open housing! A peristaltic pump might be part of a system, which is under pressure. Check pressure before opening peristaltic pump, and adjust pressure to atmospheric pressure. Flexible tube, conveying belt, contact pulleys and contact springs are the only parts of the pump subject to wear. They are simple to change. -

18.3.4 REASSEMBLY OF THE DRIVER Reassemble the driver in reverse order: 1. Insert the roll carrier back into the pump head 2. Push the pump head with the roll carrier onto the motor shaft 3. Tighten the nuts of the pump head fastening (SW 5.5) While mounting, make sure that the center of rotation and the roll carrier (driver) are aligned. -
Page 27: Operating Of The Built-In Electronic Temperature Controller
OPERATING OF THE BUILT-IN ELECTRONIC TEMPERATURE CONTROLLER New electronic temperature controllers were installed in the housing of the ECM cooler effective April 2022 and June 2023. All built-in temperature controllers are factory set to the following values: Gas outlet dew point 5 °C, alarm window 3 °C and hysteresis 1 °C. -
Page 28: 19.1.1 Changing The Set Value
19.1.1 CHANGING THE SET VALUE To change the set value the P-button has to be pushed in for < 2 sec. The default value of 5 °C [41 °F] appears. With the two arrow buttons the value can be changed. This value should not be adjusted lower than +1 °C [33.8 °F], because otherwise the heat exchanger will freeze up. -
Page 29: 19.3.1 Changing The Setpoint
19.3.1 CHANGING THE SETPOINT The temperature controller needs to be unlocked, before changing the setpoint. To unlock the device, first press the OK key for about 3 seconds. The display changes to a flashing "000". Then enter the PIN code "017" with the arrow keys and confirm the entry with OK. The display jumps back to the temperature view. -
