Replacing the water

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
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 will be dispensed:
- Start the continuous dispensing mode for each
coffee group in order to empty the tank of all its
water;
- Empty the heating unit of all its hot water by con-
tinuously dispensing through the specific spout.
If there are multiple dispensing 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 according
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 we recommend that you
do not store 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 dos-
ing 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 vacu-
um-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
wearing quickly;
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.
