14 Maintenance and care
We recommend annual maintenance of the heat pump. Thus you provide
the reliability and efficiency of your heat pump. For more information, please
contact your WATERKOTTE service partner.
In the maintenance the technical condition of the heat pump system is
checked (target-actual comparison). This provides a diagnostic measure-
ment of the thermodynamic section ensures that the efficiency is main-
tained on the top.
Typical inspection:

Check heating circuit: System pressure, function of expansion tank,
venting, rotation direction of pump and volume setting.

Check water glycol circuit: Level, if necessary pressure, water glycol
pour point, rot. direction of pump.

Groundwater: Check dirt trap and clean if necessary, rot. direction of
pump.

Check cooling circuit: Screw connections, tightness, level (inspection
glass), refrigerant control, diagnosis measurement log.

Check setting of control.

Leak test: The statutory inspection intervals depend on the refrigerant
volume. For more information, see the heat pump logbook.
