Water renewal
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 must be turned off and water fully
flushed in order to eliminate any initial impurities;
• the appliance must be filled again with water and
brought to nominal working conditions;
• upon reaching the “ready-to-operate" status, the
following operations must be performed:
- continually dispense from each coffee group, in
order to empty at least 0.5 litres from the coffee cir-
cuit. If there are several dispensing points attached
to the same exchanger/ coffee heating unit, divide
the volume by the number of dispensing points;
- flush the heating unit of all its hot water (6 litres
for 2GR, 8 litres for 3GR, 11 litres for 4GR), by con-
tinually dispensing from the appropriate nozzle.
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 idle for longer than a week, a Qualified
Technician must renew 100% of the water inside the hydraulic
circuits, as indicated above.

Preparing the machine
6.5.1 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. The following points should also be
kept in mind:
• to make 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 amounts 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 vac-
uum-sealed packs.
6.5.2 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.
6.5.3 Raised cup grilles
When using cups with different heights, use special
retractable grilles (7) that are supplied with the machine.
To use the pull-out grille, extract it from its storage
position by pulling it outwards until it is fully locked in
position.
When the grille is
no longer needed,
push it back in to-
wards the machine
until it disappears
completely into its
storage position.
