WARNING: Circulation line can lead to additional heat losses in the water tank.
USE AND MAINTENANCE
The unit is ready for use once it has been connected to water and electricity. 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 the heating pump is exposed to
dust, the lamellas of the evaporator can freeze, which can have detrimental effects to
its functioning.
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.
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?
Do not try to eliminate malfunctions by yourself, call your nearest authorized
service provider!
