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 after a certain period the resins are saturated and are to 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 use.

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 alongside shows the values of
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 installation, start-up and regeneration of the softener, refer to the
relative instruction manual.

The build-up of lime scale in the hydraulic circuit and boiler inhibit thermal exchange,
thus compromising proper operation of the machine. Heavy incrustation in the boiler
may cause long machine shutdowns and in any case invalidate any guarantee, because
this symptom indicates that regeneration has been neglected.
