Machine initial start-up

6.8
Open the water tap of the water mains and the sof-
tener.
Turn the power switch to position "1" (electricity is
supplied to the pump to automatically fill up the ma-
chine's heating unit and steam heating unit) and wait
for the heating unit to be automatically filled with water.
Turn the main switch to position "2" (full electricity is
supplied, including to the heating element in the heating
unit) and wait for the machine to fully warm up.
Before using the machine, wait a few minutes (about
10 min.) Until the pressure gauge (8) indicates the correct
working pressure (1-1,2 bar).

Replacing the water

6.10
During the installation of the machine, the Mainte-
nance Technician must replace the water contained in
the hydraulic circuits by following these steps:
• When the installation is complete, the appliance must
be started, brought to nominal working condition and
left in the "ready-to-operate" status for 30 minutes;
• Next, the appliance has to be turned off and fully
emptied of the first water introduced into the entire
hydraulic circuit, in order to eliminate any initial
impurities;
• The appliance must be filled again with water and
brought to nominal working conditions;
• Upon reaching the "ready-to-operate" status, the fol-
lowing operations must be performed:
- Continually dispense from each coffee group, in
order to empty at least 0.5 litres from the coffee
circuit;
- Empty the heating unit of all its hot water by con-
tinuously dispensing through the specific spout;
- Continuously release steam for at least 1 minute
from each steam dispensing point.
If the machine remains inactive for a time longer than 1 week, the
Maintenance Technician must renew 100% of the water contained
in the hydraulic circuit, as indicated above.
• Before using the machine, carry out some empty dispensing
cycles with the capsule holders attached for several seconds in
order 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 coffees to test the
grind fineness and to check the operating pressure of the
machine;
• Do not remove the capsule holder from the dispensing group
when coffee is being dispensed.
