FOR THE USER

Maintenance

Your heat pump requires a minimum of maintenance, however, we still

recommend some servicing to get optimal performance from your heat

pump. Check the following items a few times during the ﬁ rst year. You

should then check them once or twice a year:

Sight glass

Expansion tank

Particle ﬁ lter

Protective anode (only models with a stainless steel hot water cylinder)

Unscrew the front cover

On certain models you will need to open the front cover to access some

of the maintenance areas, e.g. the sight glass and particle ﬁ lter. The front

cover is secured at the top by two screws.

This is how you remove the front cover from the heat pump:

1. Unscrew the two screws on the top. See the picture.

2. Tilt the front cover towards you.

3. Lift the front cover up to release the lower edge.

Sight glass

Sometimes when the heat pump has started you can see the ﬂ uid in the

refrigerant circuit bubble for a few minutes in the sight glass. This is

completely normal. However, if it bubbles continuously you should contact

your dealer.

Warning

For reasons of safety the main power

supply must be disconnected before

working on the heat pump.

Only an accredited refrigeration

company is permitted to work on the

refrigerant circuit.

Remove the front cover by unscrewing the

screws on the top.

Sight glass

LWM model

If the sight glass shows green this means there is no moisture in the

system. If it is yellow, there is moisture in the system. If this happens,

contact your dealer.
