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.
6 Screw the drain cap back on.
7 Reattach the magnetic sleeve.
8 Check the pressure of the water circuit. If required, add water.
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.
▪ To prevent dirt from remaining in the dirt separator, ALWAYS take off the
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.
