3. Tighten the two cartridge holders again.
4. Check for tightness. To do so, re-establish the water supply (open water tap). If water
escapes from the screw connections of the cartridge holders, tighten the cartridges
more firmly with the filter spanner.
3.4 Cleaning the water supply tank
Clean the water supply tank each time you change the filters, but at least once per year.
Reason: Over time, deposits will form on the inner walls.
1. Switch off the water supply (turn off water tap, in case it is on).
2. Pull off the connection lines of the floating switch from the terminal strip
(Fig. 9, No. 1).
3. Pull the three feed pipes to the appliance connections (2) and the water supply tube
(3) from the filter cartridges and through the cover of the water supply tank.
4. Remove the attachment of the water supply tank (rubber band, 4).
5. Take off the water supply tank. Remove the cover and empty the tank.
6. Clean the inside of the tank with standard washing-up liquid and a brush and then
rinse it thoroughly with demineralised water.
