8.4 CLEANING FILTERS
AND FILTER-HOLDERS
Place two spoonfuls of special cleanser in half a
litre of hot water and immerse filter and filter-holder
(without its handle) in it leaving them to soak for at
least half an hour. Then rinse abundantly with run-
ning water.
8.5 RESIN AND SOFTENER
REGENERATION
To avoid scaling deposits in the boiler and in the
heating exchangers, the softener must always be
kept efficient. 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 calcu-
lated on the basis diagram illustrated in Fig. 30.
Regeneration procedures are as follows:
1) 1) Turn the machine off and place a container
large enough to contain at least 5 litres under tube E
(Fig. 31).
Turn levers C and D from left to right; take the cap off
by unscrewing knob and fill with 1 Kg normal kitchen
salt (Fig. 32).

2) Put the cap back on and reposition lever C mov-
ing it towards the left (Fig. 33), and allowing tube F to
discharge the salty water until it has been eliminated
and the water becomes fresh again (about half and
hour).
3) Reposition lever D towards the left (Fig. 34).
