Caution
Do not use tools to remove components from inside the water unit
(e.g. filter).
For certain user areas, where domestic water hardness values exceed
20 °F (200 mg of calcium carbonate per litre of water) it is recommended
to install a polyphosphate batcher or equivalent system complying with
the prevailing standards.
CLEANING THE DOMESTIC WATER FILTER
The domestic water filter is housed inside a suitable removable cartridge
positioned on the cold water inlet (B). Proceed as follows to clean:
1. Disconnect the power supply to the boiler;
2. Close the domestic water inlet cock;
3. Empty the water from the domestic water circuit by opening a user
cock;
4. Remove the clip (1-B) as shown in the figure and remove the
cartridge (2-B) containing the filter, taking care not to apply excessive
force;
5. Remove any impurities and deposits from the filter;
6. Fit the filter back inside the cartridge and reinsert it into its seat,
securing it with its clip;
Notice
If the O-rings in the water unit need to be replaced and/or cleaned,
do not use oil or grease as a lubricant, but only Molykote 111.
