The fins of copper-aluminum heat exchangers are particularly sensitive, there-
fore, use water with low-pressure for cleaning. Damaging the fins by mechanical
force leads to premature deterioration of the heat exchanger.
Corrosion spots must be cleaned and protected with zinc dust paint.
Antifreeze protection
Check antifreeze activity before each winter season. Also check the frost protection thermostat for
the correct setting.
Drain pan
Drain pan and drain should be checked for debris and cleaned, if necessary – Figure 77 .

Droplet eliminator
Check the droplet eliminator about once per year for contamination. Remove fins and clean if nec-
essary. Please make sure that the fins are installed properly and are not bent.
Pollutants can cause poor performance of the AHU as well as damage due to
drop flight.
