Renewing the water

6.4
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 (3 litres for 1GR, 6 litres for 2GR, 8 litres
for 3GR, 11 litres for 4GR) continuously dispensing
from the specific spout. In case of multiple dis-
pensing points, subdivide 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.

6.5.1 Coffee grinding and dosing
It is important to have a dosing-grinding device next
to the machine with which to grind the coffee to use
daily.
The grinding and the dosing of the coffee must be
done according to that indicated by the manufacturer
of the dosing-grinding device. The following points are
also to be kept in mind:
• to obtain a good espresso it is recommended not to
keep large stocks of coffee grains. Observe the expiry
date indicated by the producer;
• never grind large volumes of coffee, it is advisable to
have the quantity contained in the dosing device and
to use it if possible by the end of the day;
• If possible, never purchase already ground coffee,
as it deteriorates quickly. If necessary, buy it in small
vacuum-sealed packages.

6.5.2 Preparing the filter holder

• Fill the filter with a dose of ground coffee (circa 6-7
gr.) and press it with the press;
• hook the filter-holder to the unit without closing it too
tightly in order to avoid excessive wear of the gasket;
• for the same reason it is recommended to clean the
edge of the filter before attaching the filter holder to
the dispensing unit;
• follow the procedures specified by the manufacturer
of the grinder.
6.5.3 Switching on of the work top light (if fitted)
