15 MAINTANANCE
Before the maintenance work is carried out, it is necessary that the specific safety procedures
pertaining to the system and operational process be observed!
W A R N I N G !
It is necessary to take the ECP electric gas cooler off the mains
before any assembly, maintenance or repair work is carried out!
The ECP ..000 Gas Cooler requires no particular routine maintenance. Depending on the quality of the
ambient air the cooling fin block should be blown out with compressed air from time to time.
15.1 ADDING AND REPLACING THE HEAT EXCHANGERS
Removal of the heat exchangers may be necessary to carry out maintenance or repair work.
We recommend the following procedures and in this order for replacement of the heat exchangers:

Release the upper gas connections and lower condensate connections;
W A R N I N G !
Aggressive condensate is possible.
Wear protective glasses and proper protective clothing!

Pull the heat exchangers upwards with rotation out of the cooling block;
Replace the heat exchangers as follows:

Dry and clean the push-in opening in the aluminium cooling block with a cloth;

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. It is best to close off the
condensate removal of the heat exchangers tube with adhesive tape to prevent any of the thermal
conductivity paste from getting into the heat exchanger;

Lightly push the heat exchangers with rotation back into the push-in opening of the cooling block
and press to the upper block;

Remove the adhesive tape and any surplus thermal conductivity paste;

Reconnect the hoses.

Do not mix up the hose connections; gas outlet and gas inlet are marked with arrows!
