Care and maintenance
The heat exchanger requires no special care as the device is constructed in a manner
that ensures maximum operating safety and the lowest possible requirements towards
maintenance, inspection and monitoring.
However, in order to avoid faults and damages, it is necessary to observe the following
points.
1.)
The condenser blades and protective grills must be free of dust and dirt. If
necessary, these are to be cleaned using compressed air.
2.) The pipe coil evaporator should be cleaned in accordance with the state of the fluid.
Dirty fluid should thereby be drained.
3.) The air filter mat should be regularly changed.
If pollution occurs after a short time when using water as cooling fluid, the cooling water
should be prepared (see water preparation).
