2.6.21 Water filter
Mains water contains insoluble salts, which cause the
build-up of lime scale deposits in the boiler and other
parts of the machine.
Drinking water can also contain traces of heavy met-
als and substances, such as chlorine, harmful to health.
The filter makes it possible to eliminate or substan-
tially reduce the presence of these mineral salts.
The cartridge contained in the water filter must be
replaced at the frequency specified by the manufacturer.
For the water filter use and maintenance, follow the indications
by the manufacturer.
2.6.22 Softener
The resin softener can be used as an alternative to
the water filter.
This component has the property of retaining the
calcium contained in the water. For this reason, the res-
ins become saturated after a certain period and must
be regenerated with coarse kitchen salt (NaCl, sodium
chloride) or special water softening salt. It is very impor-
tant to regenerate the softener within the established
times. The regeneration is to be done regularly every 15
days. However, in locations with very hard water, it will
be necessary to regenerate more frequently. The same
is true of places in which there is a large consumption
of hot water for tea or other uses.
For the softener use and regeneration, follow the indications by
the manufacturer.
