USE AND MAINTENANCE
The unit is ready for use once it has been connected to water and electricity. Correct installation and use assures
faultless performance of the heating pump with little or no servicing or maintenance.
If there is danger of freezing, discharge the water from the hot water tank. Open the hot water tap, connected to
hot water tank. Let the water pour our through the discharge valve on the inlet hose.
The exterior of the water heater may be cleaned with a mild detergent solution. Do not use solvents and abrasive
cleaning agents. If dust deposits on the unit, use a vacuum cleaner and remove the dust, otherwise the operation
of the unit is impaired.
Before you do that, clean the evaporator. Unplug the power supply cable, undo the .xing 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 .rst 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 .owing 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 .nal control, it may happen that failure occur during the operation of the
heating pump. Should this happen, call your authorized service provider.
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!
