The yearly maintenance of the magnetic filter/dirt separator consists of:
▪ Checking if both parts of the magnetic filter/dirt separator are still screwed
tight (a).
▪ Emptying the dirt separator as follows:
1 Take off the magnetic sleeve (b).
2 Unscrew the drain cap (d).
3 Connect a drain hose to the bottom of the water filter so that the water and
dirt can be collected in a suitable container (bottle, sink...).
4 Open the drain valve for a couple of seconds (c).
Result: Water and dirt will come out.
5 Close the drain valve.

NOTICE
▪
When checking the magnetic filter/dirt separator for tightness, hold it firmly, so
as NOT to apply stress to the water piping.
▪
Do NOT isolate the magnetic filter/dirt separator by closing the shut‑off valves. To
properly empty the dirt separator, sufficient pressure is required.

magnetic sleeve.

ALWAYS first unscrew the drain cap, and connect a drain hose to the bottom of
the water filter, then open the drain valve.

Open the valve and check if it operates correctly. The water may be very hot!
Checkpoints are:

valve or in between piping is suspected.
▪ Dirty water coming out of the relief valve:
- open the valve until the discharged water does NOT contain dirt anymore
- flush the system
It is recommended to do this maintenance more frequently.
