RESIN AND SOFTENER
REGENERATION
To avoid scaling deposits in
the boiler and in the heating
exchangers, the softener
must always be kept
efficient.
An anti-flooding system
must be installed upstream
of the softener in accordance
with IEC EN 61770.
Therefore, the ionic
resins must be regularly
regenerated.
Regeneration times are
established according to the
quantity of coffee delivered
daily and the hardness of
the water utilised.
As an indication,
regeneration times can
be calculated on the basis
diagram illustrated in figure.
Regeneration procedures
are as follows:
1 Turn the machine off and
place a container large
enough to contain at
least 5 litres under tube E.
2 Turn levers C (in) and D
(out) from left to right.
3 Take the cap off by un-
screwing knob G.
4 Fill with 1 Kg normal kitch-
en salt.
5 Put the cap back on
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).
6 Reposition lever D to-
wards the left.
