Water replacement
7.4
When the machine is being installed, the Qualified
Technician must replace the water inside the hydraulic
circuits by following these steps:
When installation is complete, the appliance has to
be started, brought to the nominal working condition
and left for 30 minutes in the "ready to operate" status;
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 once again be filled with wa-
ter and brought to the nominal working conditions;
After having reached the "ready to operate" condition,
the following has to be performed:
- For each coffee group, carry out a continuous dis-
pensing, in order to empty 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 by the number of dis-
pensing points;
- Empty the boiler of all its hot water (3 litres for 1GR,
6 litres for 2GR, 8 litres for 3GR, 11 litres for 4GR),
by performing a continuous dispensing from the
appropriate nozzle. If there are multiple dispens-
ing points, divide the volume by the number of
dispensing points;
- 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.

7.5.1 Grinding and dosing coffee
It is important to have a grinder-dispenser device
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 device. The following points should
also be kept in mind:
To obtain a good espresso it is recommended to not
keep large amounts of coffee beans. Observe 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 use it if possible by the end of the day;
Do not buy pre-ground coffee, as it perishes quickly.
If necessary, buy it in small vacuum-sealed packages.
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 excessively;
For the same reason it is recommended 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.
