INSTALLATION
Installation and the following maintenance operations
should be carried out with the machine switched on and
therefore by qualified personnel only, who are trained in the
correct use of the machine and informed about the specific
risks of such situation.
The machine is not suitable for outdoor installation, it must
be installed in a dry room where the temperature remains
between 2°C and 32°C.
The machine cannot be installed where water jets are used
for cleaning.
At installation the hydraulic circuits and the parts in
contact with foodstuff should be fully sanitised to
remove any bacteria which might have formed during
storage.
MAINS SWITCHES
General
A general switch is fitted outside the machine, disconnect-
ing the power from the machine without having to open the
door.
The terminal strip supporting the line cable, the fuses
and the noise suppressor stay energised in any case.
Door
When opening the door a special micro-switch discon-
nects the power from the machine electrical system.
To energize the system with the open door, simply insert
the special yellow key into the slot (see Fig. 15).
Top panel
Also when opening the machine top panel, a micro-switch
disconnects the power, allowing loading operations in a
safe condition.
The switch on key MUST NOT be left inside the ma-
chine, it must be kept by the qualified personnel
trained in the use of the machine.
With the door open, there is no access to energised
parts. Inside the machine, the only parts that stay
energised are those protected by covers and carrying
a plate with the warning “Disconnect the power before
removing the protective cover”.
Before removing such covers disconnect the power
supply cable from the grid.
The door can be closed only after removing the key from
the door switch.
UNPACKING THE VENDING MACHINE
After removing the packing, ensure that the machine is
intact.
If in doubt do not use the machine.
No packing elements (i.e. plastic bags, polystyrene
foam, nails, etc.) should be left within the reach of
children, as they are potentially dangerous.
Packing materials must be disposed of in authorised
containers and the recyclable ones must be recovered by
qualified companies.
Important notice!!
The machine should be positioned with a maximum incli-
nation of 2°.
CONNECTING THE MACHINE
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. 15).
It is good practice to install the water supply tap
outside the machine in an easily accessible position.
