Maintenance

The heat pump requires a minimum of maintenance, however, some
servicing is still required to get optimal performance from your heat
pump. Check the following items a few times per year:

• Remove dirt and leaves

• Cover

• Evaporator

DANGER: The heat pump is connected to high current.
▶ Break the power supply before rectifying.
Using the wrong cleaning product may damage the
installation!
▶ Do not use acid or chlorine based products since they
contain abrasives.
5.1 Remove dirt and leaves
▶ Use a brush to remove the dirt and leaves from the heat pump.
5.2

Protective covers

Over time dust and other dirt will collect on the heat pump.
▶ If required, wipe the cover with a damp cloth.
▶ Scratches and damage to the outer cover should be treated with rust
protection.
▶ The lacquer can be protected with car wax.
5.3 Evaporator
If a film has formed (e.g. dust or dirt) on the evaporator surface, it must
be removed.
WARNING: The thin aluminium fins are fragile and can
be damaged if careless. Never wipe the delicate fins with
a cloth.
▶ Use protective gloves to protect your hands from
cuts.
▶ Do not use a too powerful water jet.
To clean the evaporator:
▶ Spray the evaporator fins with the cleaning product on the back of the
heat pump.
▶ Rinse off dirt and the cleaning product with water.
5.4

Snow and ice

In some geographical regions or during periods of heavy snow, snow can
get stuck on the back of the heat pump.
▶ Carefully brush the snow off the fins.
5.5

Moisture

NOTICE: If you often find moisture near the heat pump
module or the fan convector, this might indicate gaps in
the condensation insulation.
▶ Turn off the heat pump and contact your retailer of
you find moisture surrounding one of the heat system
components.
Moisture might develop under the heat pump (outdoors) due to
condensation not collected by the condensate pan. This is normal and
does not require any action.

5.6

Checking the safety valves

The safety valve should be checked by a qualified
engineer - usually as part of an annual service visit.
Water is expelled from the safety valve during heat-up.
Never close the safety valve.
▶ Check the DHW safety valve by pressing the valve lever.
▶ Check that the safety valve leakage drain hose is not plugged.
5.7

Particle filter

Check the heating system and collector system particle filters
The filters will prevent dirt from entering the heat pump. Operating
problems might occur if these are blocked.
It is not necessary to empty the installation in order to
clean the filters. Filter and shut-off valve are integrated.
Cleaning the strainer
▶ Close the valve (1).
▶ Screw off the hood (by hand), (2).
▶ Take out the strainer and clean it by running water over it.
▶ Put the strainer back; it has rails that fit into the groove in the valve to
avoid incorrect installation (3).
