Cleaning the strainer for the heating system

⚠ ⚠ ⚠
The heat pump must be switched off at the main switch before cleaning can be started.
⚠ ⚠ The brine circuit's 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.
NOTE! Have a cloth to hand when opening the strainer cover as a small amount of water usu-
ally escapes.
To clean the strainer:
1 Switch off the heat pump.
2 Turn the shut-off cock to the closed position (see figure above).
3 Unscrew the cover and remove it.
4 Remove the strainer.
5 Rinse the strainer.
6 Reinstall the strainer.
7 Check that the o-ring on the cover is not damaged.
8 Screw the cover back into place.
9 Turn the shut-off cock to the open position.
10 Start the heat pump.
