Maintenance and inspection
Have your WATERKOTTE heat pump maintained annually. This will ensure
the operational safety and efficiency of your heat pump. Additional infor-
mation is available from your WATERKOTTE service partner.
During maintenance, the technical condition of the heat pump system is
checked as well (target / actual comparison). In this process, a diagnostic
measurement of the thermodynamic part ensures that the efficiency is
maintained at an optimum level.
Note:
In the event of severe contamination it is recommended to clean the mod-
ule between maintenance cycles. At the same time, also remove residues
such as leaves and the like from the defrosting tray and check the conden-
sation drain (blockages) of the outdoor module.
Additional inspection points are:
Check heating circuit: System pressure, function of expansion tank,
venting, rotation direction of pump and volume setting.
Check cooling circuit: Screw connections, tightness, charge level, refrig-
erant control, diagnosis measurement log.
Check setting of control.
Tightness check: The legally required test intervals are dependent on re-
frigerant charge weight. Refer to heat pump log book for more detailed
information.
