dispensing comparTmenT and
vandal-proof device
To disassemble the dispensing compartment, unscrew
the knurls to release the compartment and let it slide on
the guide.The doors intended to protect the openings for
dispensing drinks and cups require no special mainte-
nance. Normal cleaning is enough.
If necessary, the knurl will help you disassemble the noz-
zle support arm.
On reassembling, pay attention to the position of the cup
shift arm, the position of the compartment on the guide
and the correct coupling of the three fastening points.
mixer channels
Use a small vacuum-cleaner or a brush to clean the fun-
nel area and the container support surface by removing
any powder residue at regular intervals.
Surfaces can be cleaned by using a wet piece of cloth.

Chapter 2
Installation
Installation and any subsequent maintenance opera-
tion must be carried out when the machine is live and,
therefore, by the personnel skilled and trained on the
use of the machine as well as aware of the specic risks
such a condition may involve.
The machine must be installed in a dry room, at a tem-
perature between 2° and 32°C and it can not be installed
in a room where water jets are used for cleaning (e.g.
large kitchens, etc.).
At the time of the installation, it is necessary to
completely sanitise the water circuits and the parts
in contact with foodstus in order to remove any
bacterium that may have built up during storage.
door swiTch
Whenever you open the door, a special switch will power
o the electric installation of the equipment.
To power on the machine when the door is open, just
insert the key into the slot (see g. 15).
When the door is open, you are not allowed to
access any live part. Only the parts protected by
covers and marked by the plate “power o before
removing the cover” will remain live inside the
machine.
Before removing these covers, it is necessary to
detach the power supply cable from the mains.
You can close the door only after having removed the
key from the door switch.
UNPACKING THE VENDING MACHINE
After having unpacked the machine, make sure that the
equipment is intact.
In case of doubt never use the equipment.
No packing material (plastic bags, foam polysty-
rene, nails, etc.) should be left within the reach of
children since they are potential sources of danger.
Packing materials shall be disposed of in authorised
dump sites and recyclable ones collected by specialised
companies.
Important!!
The machine shall be arranged to prevent maximum
inclination from exceeding 2°.
If necessary, level it by using the adjustable feet (see g.
16) supplied with the machine.

LABELS INSERTION
To insert the selection labels, disassemble the plate sup-
ports after having removed the three fastening screws by
acting on xing clips (see g. 17).
Insert the plates into the slots alternatively opening on
the right and left side.
Some buttons may not be used according to the models
(see the selection dose table).
The self-adhesive plates also supplied shall be applied
to the product containers according to the arrangement
(see the selection dose table).
WATER SYSTEM CONNECTION
The vending machine must be connected with the drink-
able water system according to the provisions in force in
the place of installation of the equipment.
The mains pressure must range from 0.05 to 0.85 Mpa
(0.5 8.5 bar).
Let water come out of the water network until it is limpid
and free of any trace of dirt.
Connect the water network with the 3/4” gas union of the
water inlet solenoid valve by means of a tube that can
support the network pressure and of a type suitable for
foodstus (min. inner diameter 6 mm.) (see g. 18).
It is recommended to apply a cock on the water net-
work outside the machine in an accessible position.
anTiflood device
The water inlet solenoid valve (see g. 18) is complete
with an antiood device that can mechanically lock the
water inlet as a result of a malfunction of the solenoid
valve or the water level control gear in the boiler.
To restore the normal operation, act as follows:
- power off the machine;
- discharge water in the overflow tube;
- close the water network cock outside the machine;
- loosen the union intended to fasten the supply tube of
the solenoid valve to discharge the residual network
pressure and tighten it again;
- open the cock and power on the machine (see fig. 18).
decalcifier
The machine is supplied without a decalcier.
If water is very hard, you can mount a decalcier.
Decalciers, available as an accessory, shall be regener-
ated according to the manufacturer’s instructions at regular
intervals

ELECTRIC CONNECTION
The machine is arranged for electrical operation at a
230 V~ single-phase voltage and it is protected by a 15A
fuse.
For connection make sure that the rating will comply with
the mains data, in particular:
- the supply voltage value shall lie within the limits rec-
ommended for the connection points;
- the main switch shall be featured in such a way that it
can support the maximum load required and to ensure
omnipolar disconnection from the mains with an open-
ing gap of the contacts of min. 3 mm.
The switch, the power socket and the correspond-
ing plug shall be located in an accessible position.
The electrical safety of the machine is only ensured
when the machine is correctly and eciently grounded
according to the safety standards in force.
It is necessary to check this fundamental safety
requirement and, in case of doubt, to require pro-
fessionally qualied personnel to check the instal-
lation carefully.
The supply cable is of the type with a xed plug. If neces-
sary, the connection cable (see g. 19) shall be replaced
by qualied personnel by using only cables of the HO5
RN - F or HO5 V V-F or H07 RN-F type, 3x1-1.5 mm2 in
cross-section.
It is forbidden to use adapters, multiple sockets
and/or extensions.
THE MANUFACTURER WILL DISCLAIM ALL RE-
SPONSIBILITY FOR ANY DAMAGE CAUSED BY THE
NON-OBSERVANCE OF THE PRECAUTIONS MEN-
TIONED ABOVE.
paymenT sysTem assemBly
The machine is sold without any payment system.
As a consequence, only the installer will be liable
for any damage that may be caused to the machine
or to things and persons by an incorrect installation
of the payment system.
Mount the payment system you have selected by follow-
ing the instructions and make sure that:
- you have programmed the parameters correctly;
- regulate the reject lever in order to open the selector
completely;
- regulate the coin slide according to the coin mecha-
nism you have assembled.
Bank insTallaTion
The control system of the machine is arranged for the
bank installation with other automatic dispensers by us-
ing special kits.
This will enable the operator to use one single pay-
ment and remote connection system (GSM) for several
machines.
In case of a bank installation, the machine can be con-
gured as a “master”, i.e. as a machine controlling the
second one, or as a “slave”, i.e. as a machine controlled
by the second one.
