4 - MACHINE INSTALLATION
4.1 Warning
The installation must be carried out by qualified
operators according to manufacturer's instruc-
tions and laws in force.
4.2 Installation Presetting
Put the machine on a plane surface with sizes
and solidity suitable to overall dimensions of the
equipment so that the cup heating level is over
150 cm from the ground. Do not use water jets
or install in places where water jets are used. To
ensure regular operation, the equipment shall
be installed in places with temperature between
+5°C and +32°C and humidity not exceeding
70%. The machine is electrically powered and
requires for its operating:
- power supply connection.
- water supply connection (R version)
- drain system connection (R version)
4.2.1 Electrical Connection
Warning:
- The installation must be carried out in com-
pliance with the laws in force and must be
equipped with proper grounding.
The machine is provided with electric cord with plug.
4.2.2 Water Supply Connection
(R version)
Make sure that the water supply installation is con-
nected to drinkable water supply with operating
pressure ranging from 0 to 6 bar (0 - 0,6 Mpa).
Should the pressure be above 6 bar (0,6 Mpa),
provide a reducer.
Provide an intercepting tap upstream the machi-
ne connection.
A pipe with G 3/8" nipple is provided for the
water supply connection.
4.2.3 Drain Connection
Connect a rubber pipe (Fig. 01; pos 14) with
inner diameter of 10 mm to the arranged con-

nector of the machine drain well and join it with
the open drain-trap, previously prepared.
4.3 Equipotential connection
(Fig. 09)
The function of this connection, required by
some standards, is to prevent the electric po-
tential differences between the masses of the
different equipment installed in the same place.
This device is provided with a terminal instal-
led under the base to connect an external wire
having a rated section in compliance with the
current regulations.

supplied to the boiler.
The machine, as alarm signal, turns on the leds
on coffee push buttons.
To restore the operation turn off and on the
main switch of the machine.
5.2 Heating
In order to have the right temperature for the ma-
chine, make sure that the pressure on the gauge
is from 1 to 1,2 bar, then turn the steam knob
(7) and let out 2 or 3 times the steam into the
drain tray. When the yellow indicator (Fig. 01;
