RESIN AND SOFTENER
REGENERATION
To avoid scaling deposits in the boiler
and in the heating exchangers, the sof-
tener must always be kept efficient.
Therefore, the ionic resins must be regu-
larly regenerated.
Regeneration times are established
according to the quantity of coffee deliv-
ered daily and the hardness of the water
utilised
These can be seen in the diagram includ-
ed in the following figure.
Regeneration procedures are as follows:
1) Turn the machine off and place a con-
tainer large enough to contain at least
5 litres under tube E.
Turn levers C and D from left to right;
take the cap off by unscrewing knob
and fill with 1 Kg normal kitchen salt.

2) 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 water becomes fresh again (about
half and hour).
