If cleaning or replacement of the water filter cartridge is necessary,
proceed as follows:
1. Close the main water valve.
2. Drain the boiler.
3. Remove the air vent hose above the siphon.
4. Remove the siphon.
5. Remove the clip holding the water filter cartridge in place. While
doing this, be sure that the silencer is left in place.
6. Remove the domestic water cartridge.
7. Rinse the water filter cartridge with tap water and, if need be, clean
it with a descaling product (e.g. citric acid with a pH of
approximately 3). After cleaning, rinse thoroughly under running
water.
8. Replace the water filter cartridge if faulty or when the maintenance
kit includes one.
9. Re-assemble all of the components.
