With some modules it may be necessary to fit a gasket to
seal the space between machine and support counter.
The gasket is supplied separately from the module.
For installation, lay the machine on its back and fit the
gasket (see figure 12) following the installation instructions
supplied with the kit.
CONNECTION TO THE WATER MAINS
Some models can 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 7.3 to 123.3 psig (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 withstanding
the water mains pressure and suitable for use with food-
stuff (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. 13).
It is good practice to install the water supply tap
outside the machine in an easily accessible position.
OVERFLOW DEVICE
The water inlet solenoid valve (see Fig. 13) is equipped
with an overflow device which mechanically stops the
water inlet if there is a malfunction in the solenoid valve or
in the boiler water level control device.
To restore normal operation, proceed as follows:
- drain the water contained in the overflow hose;
- shut off the water supply using the tap outside the
machine;
- loosen the nut which secures the solenoid valve
supply hose to relieve the water mains residual pres-
sure and then tighten again (see Fig. 13);
- open the tap and switch the machine on.
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, so that the
cable can be disconnected in the event of interven-
tion..
The power supply cable is of the type with a fixed plug. Any
replacement of the power supply cable (see Fig. 14)
should be made by qualified personnel only, using cables
of the type UL SJTO 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.
