SERVICE AND MAINTENANCE
If installed and used correctly, the heat pump will last for years without service.
The exterior of the heat pump should be cleaned with a mild detergent solution. Do
not use solvents or abrasive cleaning agents.
If the heat pump was exposed to dust, evaporator lamellas might become blocked,
which can have a detrimental effect on the functioning of the heat pump. In this case
the evaporator should be cleaned. The cleaning of the evaporator must be carried out
by an authorised service provider.
By performing regular service inspections you can ensure faultless operation and a
long life span of the heat pump. The tank corrosion warranty applies only if the
prescribed regular anode inspections have been performed. The interval between
individual inspections should not be longer than 36 months. Inspections must be
carried out by an authorised service provider that logs each inspection on the
product’s warranty sheet. The service provider inspects the wear and tear of the anti-
corrosion protective anode and cleans the limescale that accumulates inside the tank,
depending on the quality, quantity and temperature of the water used. Service
providers will also provide you with the following inspection date, depending on the
state of the heat pump.
Before calling your service provider, check the following:
