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.
