When the machine is being installed, the Qualified
Technician must replace the water inside 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;
Then, the appliance must be filled with water and
brought to the nominal working conditions;
Upon reaching the "ready-to-operate" status, the
following dispensing operations must be performed:
- Continually dispense from each coffee group, in
order to empty at least 0.5 litres from the coffee
circuit. If there are several dispensing points for
the same exchanger/ coffee heating unit, divide
the volume by the number of dispensing points;
- Empty the heating unit of all its hot water (6 litres
for 2GR, 8 litres for 3GR, 1 litres for 4GR), by con-
tinually dispensing from the appropriate nozzle.
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
Qualified Technician must renew 100% of the water inside the
hydraulic circuits, as indicated above.
Before using the machine, carry out some empty dispensing
cycles with the filter 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 filter holder from the dispensing group when
coffee is being dispensed.
