Installation
Preparation of the machine
The preparation of the coffee machine
and its installation must be performed by
qualified staff.
Starting the machine
Open the water tap of the water mains
and of the softener / water filter.
Turn the switch to position “
1
”
(electrical power supplied to the pump for
automatic boiler filling and machine
services) and wait for the boiler to be
automatically filled with water.
Turn the switch to position “
2
” (full
electrical power suppled, including the
heating element in the boiler) and wait for
the machine to warm up completely.
Wait for the pressure to reach its
operational pressure 1.1÷1.3 atm
checking the boiler pressure on the
gauge
Should the machine fail to stabilize on the
indicated values it is
necessary to calibrate the pressure
switch as described in calibration
paragraph.
Then check the pressure on the pump
gauge putting a unit into
operation with filter holder engaged filled
with ground, dosed and
pressed coffee in order to achieve an
effective working pressure of
8/9 atm.
Should re-calibration of the pump
pressure be necessary this
operation should be undertaken as
indicated in the “calibration” paragraph.

WARNING
Use of the machine without all the
installation operations having been carried
out by technical personnel could damage it
seriously.
WARNING
During the machine’s warm-up (roughly
20 minutes), the negative pressure valve
will release steam for a few seconds until
the valve itself closes.
Before using the machine, run deliveries
with the filter holder attached for a few
seconds to release any air which may be
in the circuit, so that the head groups are
completely heated.
The user must be provided with
instructions in order to use the machine
properly. It is recommended not to take
actions which may disturb the functions of
the machine.
WHEN THE MACHINE IS SWITCHED
ON, ITS BOILER CONTAINS STEAM
AND WATER UNDER PRESSURE
