MAINTENANCE

NOTE: During maintenance/repairs, the parts
used must be able to guarantee compli-
ance with the safety and hygiene
requirements envisaged for the device.
Original replacement parts can offer
this guarantee.
NOTE: After the repair or replacement of any
components of parts that come into
contact with food or water, it is neces-
sary to carry out the washing procedure
to the manufacturer's instructions.
7.1 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.
These can be seen in the diagram included in
the following 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.
Turn levers C and D from left to right; take
the cap off by unscrewing knob and fill with
1 Kg normal kitchen salt.

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).
