12.1 Softener

Mains water contains insoluble salts, which cause
the build-up of lime scale deposits in the boiler and
in other parts of the machine. The softener makes
it possible to eliminate or substantially reduce the
presence of these mineral salts. The resin softener
has the property of retaining the calcium contained
in the water. For this reason, the resins become
saturated after a certain period and must be re-
generated with coarse kitchen salt (NaCl, sodium
chloride) or special water softening salt. It is very
important 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 rule can be applied to
places where there is a large consumption of hot
water for tea or other uses.
Softener regeneration
Proceed as follows:
move levers (B) and (E) from left to right;
remove the lid by loosening the knob (A);
release enough water through the pipe (C) to
make room for the amount of salt as required
depending on the model (see table);
clean any salt or resin residue from the gasket
located on the lid;
put the cover back in place by screwing the knob
(A) down securely and move the lever (B) back
from right to left;
let the salt water drain from the little hose (D)
until the water is no longer salty (about 30-60
minutes). The salt allows the accumulated min-
eral salts to be released;
switch the lever (E) from right to left back to its
initial position.

User manual
The build-up of lime scale deposits in the hydraulic
circuit and boiler inhibits thermal exchange, thus
compromising proper operation of the machine.
i
Heavy incrustations in the boiler may cause long
machine shutdowns and in any case invalidate any
guarantee, because this symptom indicates that
regeneration has been neglected.
In order to keep the softener and hence the ma-
chine in perfect operating condition, it is necessary
to perform regeneration periodically based on the
use of the softener and the hardness of the water
that is used. The table below shows the quantity of
softened water based on the hardness of the water
in the various units of measure:
°f French degree
°d: German degree = 1.8 °f

For further information on installation, start-up
and regeneration of the softener, refer to the relative
instruction manual.
