Softener regeneration
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 where
water is very hard, it will be necessary to regenerate it
more frequently. The same is true of places in which there
is a large consumption of hot water for tea or other uses:
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 regener-
ate it regularly, based on use of 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 measure:
•
°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.
