3 SAFETY INSTRUCTIONS
Please take care of the following basic safety procedures when mounting, starting up or
operating this equipment:
Read this operating manual before starting up and use of the equipment. The information and
warnings given in this operating manual must be heeded.
Any work on electrical equipment is only to be carried out by trained specialists as per the regulations
currently in force.
Attention must be paid to the requirements of VDE 0100 (IEC 364) when setting high-power electrical
units with nominal voltages of up to 1000 V, together with the associated standards and stipulations.
Check the details on the type plate to ensure that the equipment is connected to the correct mains
voltage.
Protection against touching dangerously high electrical voltages:
Before opening the equipment, it must be switched off and hold no voltages. This also applies to any
external control circuits that are connected.
The device is only to be used within the permitted range of temperatures and pressures.
Check that the location is weather-protected. It should not be subject to either direct rain or moisture.
The gas cooler ECM must not be used in hazardous areas.
Installation, maintenance, monitoring and any repairs may only be done by authorized personnel with
respect to the relevant stipulations.

6 INTRODUCTION
The patented M&C ECM 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.
6.1 SERIAL NUMBER
The type plate with the serial number is located at the side panel of the cooler housing (wall mounting
version). Whenever you call M&C regarding questions or orders for the spares please give us the
serial number of your ECM.
7 APPLICATION
Figure 1 shows a typical example of an application for installation of an ECM-ExII gas cooler unit.
Figure 1 Application example of the ECM
1 : Filter sample probe SP ...
2 : Heating sample line
3 : ECM cooler
4 : 3-way ball valve
5 : Peristaltic pump (option)
6 : Membrane pump
7 : Super fine filter FP ...
8 : Aerosol filter CLF-5
9 : Flow meter FM10
10 : Analyser
The gas to be measured is taken from the ECM 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 .
