RESIN AND
SO FTENER
REGENERATI ON
To avoid scaling deposits in
the boiler and in the heat-
ing exchangers, the softener
must always be kept effi-
cient.
A CEI EN 61770 compliant
non-return system must be
installed upstream of the
softener.
Therefore, the ionic resins
must be regularly regener-
ated.
Regeneration times are es-
tablished according to the
quantity of coffee delivered
daily and the hardness of
the water utilised.
As an indication, regenera-
tion times can be calcu-
lated on the basis diagram
illustrated in figure.

Regeneration procedures
are as follows:
Turn the machine off and
1
place a container large
enough to contain at
least 5 litres under tube E.
Turn levers C (in) and D
2
(out) from left to right.
Take the cap off by un-
3
screwing knob G.
Fill with 1 Kg normal kitch-
4
en salt.
Put the cap back on
5
and reposition lever C
moving it towards the
left and allowing tube
F to discharge the salty
water until it has been
eliminated and the wa-
ter becomes fresh again
(about half and hour).
Reposition lever D to-
6
wards the left.
