2.8.17 Water filter
In the mains water, non-soluble salts are
present which cause limestone to form
in the heating unit and other parts of the
machine.
Drinking water can also contain heavy
metals and substances, such as chlorine
which are harmful to health.
The filter makes it possible to eliminate or
substantially reduce the presence of these
mineral salts.
The cartridge contained in the water filter
must be replaced at the frequency speci-
fied by the manufacturer.
To use and maintain the water filter, follow the in-
structions provided in para. "7.5 Water filter mainte-
nance" on page 34
2.8.18 Water softener
The resin softener can be used as an alternative to the water
filter.
This component has the property of retaining the calcium con-
tained in the water. For this reason, the resins
become saturated after a certain period and
must be regenerated with coarse kitchen salt
(NaCl, sodium chloride) or special water sof-
tening salt. It is very important to regenerate
the softener within the established times.
However, in locations where the water is very
hard, it will be need to be regenerated more
frequently. The same rule can be applied to
locations where there is a large consumption
of hot water (for tea, etc.).
To use and regenerate the water softener, follow the
instructions provided in para. "7.6 Water softener re-
generation" on page 36.
