6.7 Water renewal
Nel corso dell'installazione della macchina, il Tecnico deve ef-
fettuate le operazioni di rinnovo dell'acqua contenuta nei cir-
cuiti idraulici seguendo questa procedura:
When the machine is being installed, the Technician must re-
place the water inside the hydraulic circuits by following these
steps:
• When the installation is complete, the appliance must be
started, brought to the nominal working condition and left
in the “ready-to-operate” status for 30 minutes.
• Next, the appliance has to be turned o and fully emptied
of the first water introduced into the entire hydraulic cir-
cuit, in order to eliminate any initial impurities.
• The appliance must then be filled again with water and
brought to nominal working conditions.
• Upon reaching the “ready-to-operate" status, the follow-
ing dispensing operations must be performed:
- Continually dispense from each coee group, in order
to empty at least 0.5 litres from the coee circuit. If
there are several dispensing points attached to the
same exchanger/coee heating unit, divide the volume
by the number of dispensing points.
- Empty the heating unit of all its hot water by continu-
ously dispensing through the specific spout. If there are
multiple dispensing points, divide the volume by the
number of dispensing points.
- Continuously release steam for at least 1 minute from
each steam dispensing point.
If the machine remains inactive for longer than a
week, the Technician must renew 100% of the water
inside the hydraulic circuits, as indicated above.
Before using the machine, run a few empty dispens-
ing cycles with the filter holder attached for a few sec-
onds to release any air inside the circuit and in turn,
allow the dispensing groups to fully heat up.
Before using the machine, dispense a few coees to
test the grind fineness and to check the operating
pressure of the machine.
6.8 Dispensing coee
Do not remove the filter holder from the dispensing
group when coee is being dispensed.
The coee dispensing method is dierent for each machine
type; therefore, the instructions specific to the model being
used must be followed.
In any case, before dispensing, the filter holder must be filled
as described in the next paragraph.
6.8.1 Preparing the filter holder
Before filling the filter holder, make sure it is empty
and any previous coee residue has been removed.
• Fill the filter with a dose of ground coee (approx. 6-7 g);
follow the procedures specified by the manufacturer of the
grinder-dispenser.
• Tamp the coee with the special tamper.
• Clean the rim of the ground coee filter before attaching
the filter holder to the dispensing group.
• Hook the filter holder to the group without closing it too
tightly in order to prevent the gasket from wearing quickly.
6.8.2 Dispensing
• Place a cup/demitasse under the group’s dispensing spout.
• Press the desired dose button, e.g.
and wait for the
coee to be dispensed (LED will switch on).
• To stop the coee from dispensing ahead of time, press
the
button again or the
STOP
PROG.
button.
Should an anomaly occur or the pushbutton panel
freeze, use the manual switch
