6.8 Replacing the water

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;
• 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 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 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.
