Caution
Do not use tools to remove components from inside the water unit (e.g. filter).
For certain user areas, where water hardness values exceed 15 °F (1 °F = 10 mg of calcium carbonate per litre of water) it is
recommended to install a polyphosphate batcher or equivalent system that complies with the prevailing standards.
CLEANING THE FILTERS
The domestic water filter is housed inside a removable cartridge. The domestic water circuit is positioned on the cold water inlet.
Proceed as follows to clean the filter:
1. Disconnect the power supply to the boiler;
2. Close the domestic water inlet cock;
3. Remove the filter by loosening the cartridge (B);
4. Remove any impurities and deposits from the filter;
5. Fit the filter back inside the cartridge and reinsert it into its seat, securing it with a suitable spanner.
