Maintenance and care
We recommend annual maintenance of the heat pump. Thus you provide the reli-
ability 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 measurement of the ther-
modynamic section ensures that the efficiency is maintained 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, rotation 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.
Tipp:
A continuous diagnosis (CD) is performed with help of the WWPR controller. If the
measured values or queries are beyond the permissible range in the respective
mode, the controller issues a warning.
