4 - MACHINE INSTALLATION

4.1 Warnings

Installation must be carried out by qualified staff,
following the instructions provided by the manufacturer
and in observance of the current laws in force.
4.2 Preparation of the plant for
installation
Prepare the base for the machine on a flat, dry,
smooth, strong, stable surface, placed high enough
so that the cup heating shelf is more than 150 cm
from the ground. Do not use jets of water or install
the machine in places where water jets are used.
To ensure normal running, the machine must be
installed in places with a temperature range of
+5°C - +32°C and with maximum humidity of
70%. The machine is powered electrically and
needs the following to function:
- connection to the electrical power circuit
- connection to the water supply (R version)
- connection to the discharge system (R version)
4.2.1 Connection
power circuit
Warnings:
- The plant must be built in compliance with the
current laws in force and be earthed.
The machine must be supplied with an electrical
power cable with a fitted plug.
4.2.2 Connection to the water supply
system
(R VERSION)
Make sure that the water supply is connected to
a drinking water network with working pressure of
0 - 6 bar (0 - 0.6 MPa).
In the event that the water supply system has
a pressure of more than 6 bar (0.6 MPa), fit a
pressure reducer. Fit a water interception tap above
the machine attachment. The water loading pipe is
supplied with a thread diameter of 3/8"G.
4.2.3 Connection to discharge network
(R VERSION)
Connect a rubber pipe, (Fig. 01; pos. 14) with
an internal diameter of 10 mm, to the union on
the machine's discharge bowl and to a previously
prepared open syphon discharge.

4.3 Equipotential connection

This connection, foreseen by some laws, acts to
avoid differences in electrical potential between the
equipment masses installed in the same room. This
equipment is fitted with a clamp under the base to
connect to an external wire with a nominal section
in compliance with the current laws in force.

5 - MACHINE USE

5.1 First machine start and water
loading in the boiler
Open the water interception tap (R version).
Pour water into the tank (S version), checking that
the aspiration pipe touches the bottom (Fig. 03).
Insert the plug in the electrical socket.
Turn the main switch (Fig. 01; pos. 1) to position
1.
Water is automatically loaded into the boiler.
PM VERSION
A safety device will interrupt the motor-pump after
120 seconds if the maximum water level is not
reached in the boiler.
To restore working mode, turn off and turn on the
machine again.
DE VERSION
A safety device will interrupt the motor-pump after
120 seconds if the minimum water level is not
reached in the boiler.
The machine will signal this alarm by turning off the
yellow light and turning on the keypad LEDs.
To restore working mode, turn off and turn on the
machine again.

5.2 Heating

In order for the machine to reach the right
temperature, with the pressure indicated on the
boiler gauge (Fig. 01; pos. 11) between 1 and 1.2
bar (0.1 - 0.12 MPa), open the steam tap (Fig. 01;
pos. 9) and discharge the steam 2 or 3 times into
the discharge basin.
The yellow light (Fig. 01; pos. 3), if turned on
indicates that the machine is working correctly, if
turned off means insufficient water in the tank (S
version), in the boiler (R version).

5.3 Preparing coffee

1) Remove the filter holder (Fig. 01; pos. 6) from
the distribution unit (Fig. 01; pos. 5).
