Installation- and Operation Instruction
Messgaskühler / Sample Gas Coolers PKE-5xx
If the sample gas pump is installed downstream the cooler, we recommend using glass condensate vessels or
peristaltic pumps.
Mounting the condensate drains: depending on the used material the condensate drain may be connected to
the heat exchanger directly by stainless steel pipes or hoses. The condensate drains can be attached directly
to such coolers with stainless steel heat exchangers. In case of glass heat exchangers the condensate drains
must be connected with flexible hoses and fixed with by brackets separately. The condensate lines must be
installed with considerable slope and should not have less than 8 mm (0.3 inch) inner diameter.
If peristaltic pumps are used, they may be installed in some distance from the cooler.

3.2 Electrical Connection

The device must be installed by trained staff only.
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
Damage to the device in case of insulation testing
Do not proceed insulation tests with high voltage to the device as a whole.
The device is equipped with extensive EMC protection. If insulation tests are carried out the electronic filter
devices will be damaged. All necessary tests have been carried out for all concerned groups of components at
the factory (test voltage 1 kV or 1.5 kV respectively, depending on the device).
The PKE5xx is equipped with two connectors on top of the unit. One connector is for the power supply and the
other one for the alarm output. They cannot be interchanged and must be wired according to the following
diagram (numbering can be found on the connectors). Make sure they are correctly refitted after wiring.
If the PKE 5xx is equipped with peristaltic pumps, they must be connected to a separate power supply.
