3-core machines
220 V - 240 V SINGLE PHASE WITH NEUTRAL WIRE (1-2-3 GROUP MACHINES)
The machine can be connected to supplies with a single phase of 220-240 V. In this case, the Black cable must
be joined to the phase in the permanent electrical installation. The White/Black cable must be connected to the
neutral wire. The Green cable must be connected to the earth.

Phase (R)
110 V SINGLE PHASE WITH NEUTRAL WIRE (1-2 GROUP MACHINES)
IMPORTANT: The machines manufactured for use with electrical voltages of
110 V have been manufactured with electrical elements specifi cally for that
voltage. They can thus only be installed at a voltage of 110 V, as indicated on
the specifi c electrical diagram for these voltages.
The machine can be connected to power supplies with a single phase of 110 V. In this case, the Black cable must
be connected to that phase, and the White/Black cable to the neutral wire. The Green cable must be connected to
the earth.

3.4.- FEED GROUP
a) Gasket: facilitates the adjustment of the fi lter holder in the group.
b) Showerhead: where the water is in contact with the coff ee.
c) Drainage device.
d) Solenoid valve: it allows the passage of water to the unit when a button on the button pad
is pressed.
The feed group is a pressed brass block in which there is a brewing chamber. When any button on the button pad
is pressed, the pump is started and the solenoid valve is ENABLED.
3.5.- BOILER
a) Feed group.
b) Injector.
c) Heat exchanger.
This boiler is manufactured in copper and a heat exchanger connected to the power supply unit passes through it.
During a supply cycle, cold water is pumped to the coff ee boiler through the injector. In turn, the water inside the
coff ee boiler is taken to the feed group. Under rest conditions there is permanent fl ow of water between the feed
group and the coff ee boiler, which keeps the equipment at the optimum temperature for coff ee preparation.
The temperature of the heating elements within the boilers is limited by thermostats. Should the element
temperature exceed that established by the thermostat, the machine will cut the power supply. In order to connect
the elements once more, push the reset button located on the thermostat.
