INSTALLATION
Installation and the following maintenance operations
must be carried out by qualified personnel only, trained
in the correct use of the machine and informed on the
specific risks of such operations.
The machine must be installed in a dry room, where
the temperature stays always between 2° C and 32° C.
At installation it is necessary to completely sanitise
the hydraulic system and all parts in contact with food,
in order to eliminate any possible bacteria formed
during storage.
UNPACKING THE VENDING MACHINE
After removing the packing, check that the machine is not
damaged.
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 authorized areas
only, and all recyclable materials must be recovered by
specialised companies.
Important notice!!
The machine should be positioned with a maximum incli-
nation of 2°.
If necessary provide proper levelling by way of the adjust-
able feet included (see Fig. 3).
INSERTING THE LABELS
The menu and instruction labels, as well as the self-
adhesive labels to identify the product containers, are
supplied with the machine and must be inserted or at-
tached at the time of installation (see "selection dose"
table).
CONNECTING THE MACHINE
TO THE WATER MAINS
The machine must be connected to the drinking water
mains.
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 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. 4).
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. 4) is equipped with
an overflow device mechanically preventing the water from
flowing in, if there is a malfunction in the solenoid valve
itself or in the control device of the boiler water level.
To restore normal operation, proceed as follows:
- drain the water contained in the overflow pipe;
- shut off the water supply tap outside the machine;
- loosen the union which secures the solenoid valve supply
tube to relieve the water mains residual pressure and
then tighten again (see Fig. 4);
- open the tap and switch the machine on.
