Water replacement
During the installation of the machine, the Qualified
Technician must replace the water contained in the hy-
draulic circuits by following these steps:
•
when installation is complete, the appliance has to
be started, brought to the nominal working condi-
tion and left for 30 minutes in the "ready to operate"
condition;
•
afterwards, the appliance has to be turned off and
emptied of the first water introduced in the whole hy-
draulic circuit, to eliminate possible initial impurities;
•
then, the appliance must be loaded and brought to
the nominal working conditions;
•
turn off the machine again and empty the water
circuit;
•
turn on the machine, then load it and bring it to the
nominal working conditions;
•
when the "ready to operate" status is reached, carry
out continuous dispensing for each coffee unit, in or-
der to release at least 0.5 liters from the coffee circuit.
•
continuously release steam for at least 1 minute for
each steam dispensing point.
If the machine remains inactive for a time longer than 1 week, the
Qualified Technician must renew 100% of the water contained in
the hydraulic circuit, as indicated above.
•
Before using the machine, run dry deliveries with the filter
holder attached for a few seconds to release any air which may
be in the circuit, so that the dispensing groups are completely
heated;
•
before using the machine, dispense a few servings of coffee to
test the grinding and to check the operating pressure of the
machine
•
during dispensing of coffee, do not remove the filter holder
from the brewing.
