checked regularly, the water tank might be damaged. It is quite normal
that the safety valve lets out small amounts of water when the water
tank is being charged, especially if a lot of hot water was used previ-
ously.
Both safety valves can be checked by turning the cap a quarter of a turn
clockwise until the valve lets out some water through the overflow pipe.
If a safety valve does not work properly, it must be replaced. Contact
your installer.
The opening pressure of the safety valves is not adjustable.

In the event of leakage in the hot water pipes between the heat pump
and water taps, close the shut-off valve on the cold water inlet immedi-
ately. Then contact your installer.
6.5 Cleaning the strainer for the heating circuit
The heat pump must be switched off at the main switch before
cleaning can be started.
The strainer must be cleaned twice a year after installation. The
interval can be extended if there is evidence that cleaning twice
a year is not necessary.
Have a cloth to hand when opening the strainer cover as a
small amount of water usually escapes.
