7.5 Water softener regeneration
It is very important to regenerate the softener within the es-
tablished times. The regeneration is to be carried out regu-
larly: every 15 days. 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.).
Proceed as follows:
• Move the lever (B) and (E) from left to right.
• Remove the lid by unscrewing the knob (A).
• Release enough water through the pipe (C) to make room
for the amount of salt required depending on the model
(see table).
• Clean any salt or resin residues from the gasket located
on the lid.
• Put the cover back on by securely screwing the knob (A)
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 limescale in the hydraulic circuit
and heating unit inhibits thermal exchange,
which prevents the machine from working prop-
erly. Heavy incrustations in the heating unit may cause
long machine shutdowns and in any case invalidate any
guarantee, because this symptom indicates that the re-
generation procedure has not been carried out.

In order to keep the water softener, and hence the machine,
in perfect operating condition, it is necessary to regularly re-
generate it, depending on the softener and hardness of the
water used. The table below shows the quantity of softened
water based on the hardness of the water in the various units
of measurement:
• °f: French degree
• °d: German degree = 1.8°f
• mg CaCO3
For further information on softener installation, start-up and
regeneration, refer to the instruction manual.
