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:

7.1 REMOVING THE EXTERNAL CASING

Some maintenance areas are only accessible after

removal of the external casing.

them a quarter turn.

the bottom.

7.3 PROTECTIVE COVERS

Over time dust and other dirt will collect on the heat

pump.

B Wipe the outside with a damp cloth if necessary.

B Scratches and damage to the outer plates should be

touched up using an anti corrosive rust-inhibitor.

B Use normal car polish to protect the paint.

7.4 FILTER

The filter prevents particles and dirt from entering the

heat pump interior. Over time, the filter can become

blocked and must be cleaned.

DANGER: The heat pump is connected to

high current.

B Break the power supply before rectifying.
