Renewing the water

7.4
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;
following this, the equipment must be charged again
and taken to its nominal operating conditions;
After having reached the "ready for operation" status,
the following dispensing actions must be carried out:
- for each coffee unit, carry out a continuous deliv-
ery, in order to release at least 0.5 litres from the
coffee circuit. In the case of several dispensing
points matched with the same exchanger/coffee
boiler, divide the volume on the base of the num-
ber of the dispensing points;
- discharge the whole volume of hot water from the
boiler (6 litres for 2GR, 8 litres for 3GR, 11 litres for
4GR) continuously dispensing from the specific
spout. In case of multiple dispensing points, sub-
divide this volume according to the number of
dispensing points;
- 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.
