CONNECTING THE MACHINE
TO THE POWER SUPPLY
The machine is designed to operate under a single-phase
120 V~ voltage and is protected by 15 A fuses.
Before making the connection, ensure that the rating
corresponds to that of the power grid, and more specifi-
cally:
- the supply voltage rating must be within the range
recommended for the connection points;
- the main switch should be capable of withstanding the
peak load required, and at the same time ensure
proper omnipolar disconnection from the power grid
with an opening gap of the contacts of at least 3 mm.
The switch, the power outlet and the plug must be
located in an easily accessible position.
The power supply cable is of the type with a fixed plug. Any
replacement of the power supply cable (see Fig. 3) should
be made by qualified personnel only, using cables of the
type UL SJT 3x16 AWG.
The electrical safety of the machine is ensured only when
it is correctly earthed according to the safety standards
in force.

This fundamental safety requirement must be duly
verified, and if in doubt the system must be carefully
tested by qualified technicians.
Do not use adapters, multiple sockets and/or exten-
sions.
Before switching the machine on, be sure it is correctly
connected to the water mains and the cut-off valve is open.
THE MANUFACTURER DECLINES ALL RESPONSI-
BILITY FOR ANY DAMAGE CAUSED BY NON-COM-
PLIANCE WITH THE ABOVE MENTIONED SAFETY
RULES.
CONNECTING THE MACHINE
TO THE WATER MAINS
The machine must be connected to the drinking water
mains, taking into account law provisions in force in the
country where the machine is installed.
The water pressure must be 5 to 85 N/cm
2 (0.5-8.5 bar).
Run some water from the mains until it is clear and without
impurities.
Use a hose (also available as a kit) capable of withstand-
ing the water mains pressure and suitable for use with
foodstuff (min. inside diameter of 6 mm) to connect the
water supply to the union (3/4" gas) of the water inlet
solenoid valve (see Fig. 4).

It is advisable to install the water supply tap outside
the machine in an easily accessible position.
