Removing the lower filter
- Loosen screws A and B enough to release the coffee
funnel (see fig. 19);
- remove the lower piston snap ring;
- take the piston out of brewing chamber and remove the
filter.
Soak all components removed from the unit in a solution of
boiling hot water and coffee machine detergent for approx.
20 minutes.
Thoroughly rinse and dry all parts, then reinstall them in the
reverse order of disassembly, taking particular care that:
- the piston is positioned in the correct notch for the coffee
dose used (see relevant section);
- the two reference notches match and that the coffee unit
is inserted.
Important notice!!!
Check that the handle pin of the ratiomotor is correctly
engaged in its seat.
The integrity of the machine and compliance with the
standards of the relevant systems must be checked at
least once a year by qualified personnel.
Before starting any maintenance operations requiring
parts of the unit to be removed, the machine must
always be switched off.
The operations described below must be carried out
only by personnel who have the specific knowledge of
the machine functioning from a point of view of elec-
trical safety and health regulations.
INTRODUCTION
To ensure correct operation for a long period, the machine
must be subjected to regular maintenance.
The following sections contain the procedures and the
maintenance schedule, which are only a general indica-
tion, as they greatly depend on the operating conditions
(e.g. water hardness, environmental humidity and tem-
perature, type of product used, etc.).
The procedures described in this chapter are not exhaus-
tive of all maintenance operations to be carried out.
More complex operations (e.g. boiler descaling) should be
carried out by qualified technicians only having specific
knowledge of the machine.
To prevent oxidation or the action of chemical agents, the
stainless steel and varnished surfaces should be kept
clean by using mild detergents (solvents must not be
used).
Under no circumstances should water jets be used to
clean the machine.
ESPRESSO UNIT MAINTENANCE
Every 10,000 selections or every 6 months some mainte-
nance of the coffee unit must be carried out.
Maintenance is carried out as follows:
- remove the boiler Teflon hose connection from the upper
piston, paying attention not to lose the seal (see Fig. 19);
- undo the knob securing the unit to the bracket;
- remove the coffee unit.
Removing the upper filter
- Take the snap ring out of its seat;
- remove the piston from the crosspiece;
