Before you do that, clean the evaporator. Unplug the power supply cable, undo the
fixing screws of the plastic cover, and remove the cover. Use a vacuum cleaner and
clean the lamellas (alternatively, you can also use a compressor).
Regular preventive maintenance inspections ensure faultless performance and
long life of your heating pump. The first of these inspections should be carried out
by the authorised maintenance service provider within two years from the date of
installation in order to check the wear of the protective anticorrosion anode and
remove any build-up of calcium and lime as required. The build-up of calcium and
lime in the hot water tank depends on the quality, quantity and temperature of
water flowing through the heating pump. The maintenance service provider shall
also prepare a status report and consequently recommend the date of the next
inspection.
In spite of monitored manufacture and final control, it may happen that failure occur
during the operation of the heating pump. Should this happen, call your authorized
service provider.
WARNING: If water temperature during the operation of the hot water tank rises over
60 °C, this definitely is a defect; call your authorized service provider
immediately!
Before calling your service provider, check the following:
- Is everything OK with the power supply network?
- Is the air outlet obstructed (evaporator may freeze)?
- Is ambient temperature too low (evaporator may freeze)?
- Can you hear the operation of the compressor and fan?
- Is the amount of the discharged condensate still the same (or is it reduced)?
Do not try to eliminate malfunctions by yourselves, call your nearest
authorized service provider!
