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 resins 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 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 is true of places in which 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 mineral salts to be released;
• switch the lever (E) from right to left back to its initial
position.
The build-up of lime scale in the hydraulic
circuit and boiler inhibit thermal exchange, thus
!
compromising proper operation of the machine.
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 machine
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
• mg CaCO

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

Regeneration request
If the function has been enabled during the
programming, the system measures the amount of
water used by the machine and prompts the user for
regeneration (
) when the set amount has been
exceeded.
Once the regeneration has been carried out, the
counter must be reset (see chapter 28).
