Water renewal
7.4
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;
Turn the machine off again and empty all the water
in the hydraulic circuit;
Turn the machine back on, then fill it and bring it to
the nominal working conditions;
When the "ready to operate" status is reached, con-
tinuously dispense from each coffee group, in order
to empty the coffee circuit of at least 0.5 litres.
Continuously release steam for at least 1 minute from
each steam dispensing point.
If the machine remains idle for longer than a week, a Qualified
Technician must renew 100% of the water inside the hydraulic
circuits, as indicated above.

7.5.1 Grinding and dosing coffee
It is important to have a grinder-dispenser next to the
machine so that the coffee can be ground on a daily basis.
The coffee must be ground and dispensed accord-
ing to instructions provided by the manufacturer of the
grinder-dispenser. The following points should also be
kept in mind:
To make a good espresso, we recommend that you
do not store large amounts of coffee beans. Comply
with the expiry date indicated by the producer;
Never grind large volumes of coffee, it is advisable to
prepare the amount that can be held in the dosing
device and if possible, use it by the end of the day;
Do not buy pre-ground coffee, as it perishes quickly.
If necessary, buy coffee
in small vacuum-sealed
packs.
7.5.2 Preparing the filter holder
Fill the filter with a dose of ground coffee (approx. 6-7
g) and compress it with the press;
Hook the filter holder to the group without closing it
too tightly in order to prevent the gasket from wear-
ing quickly;
For the same reason we recommend that the edge of
the filter is cleaned before attaching the filter holder
to the dispensing group;
Follow the procedures specified by the manufacturer
of the grinder-dispenser.
