According to current health and safety regulations, the
operator of vending machines is responsible for their
hygiene and cleaning.
It is advisable to use sanitising products (chlorine based
detergent or similar) to clean all surfaces even if not in
direct contact with food.
Some parts of the machine can be damaged by strong
detergents.
The manufacturer declines all responsibility for damage
caused
by non-compliance with the above instructions or by the
use of strong or toxic chemical agents.
Under no circumstances should sprayed water be
used.
Before any maintenance operation always switch the
machine off.
Asstandardfeatureorusingspecialkits,themachinecan
be equipped with small compartments, suitable for dis-
pensing cans, plastic bottles up to 69 mm dia., 0.2 litre
Tetra-Paks.
The compartments equipped in this way can be recog-
nisedbytheshapeoftheproductsupportbracket(seeFig.

ASSEMBLING THE VENDING MACHINES
To assemble master and slave vending machines do as
follows:
- Check that side ventilation grilles of the machines
equipped with a cooling unit are completely free.
Should the ventilation grilles be covered, even partially,
due to the layout to be adopted, it will be necessary to
fit the spacer (see Fig. 15) supplied with the machine.
Important notice!
Thebankofmachinesshouldinanycasebeatleast4cm
from the wall so that correct ventilation may be ensured.
- Ensure that the inclination of the machines does not
exceed 2°; If necessary provide proper levelling by
way of the adjustable feet included; the feet must be
adjusted to keep the machines side by side at the
same height.
- Secure the clamping bracket to the left side of the
master machine and position it next to the vending
machine; connect the connectors of the external can-
bus cable.
- Line up the front of the two vending machines, taking
care not to pull the external can-bus cable and not to
damage the cabinet with the protruding clamping
bracket.
- Secure the clamping bracket to the top panel of the
slave machine. Secure the two vending machines with
the screw at the base.

CONTROLS AND INFORMATION
The machine can be used only as slave, therefore the
control functions are handled by the master machine.
Themainswitch,whichisofthemanualtype,disconnects
the machine in the event of maintenance operations.
The information for the user (sales price and selection
number)isindicated on self-adhesive labels to be placed
in front of the spirals during installation.
INTERNAL COMPONENTS
The evaporator assembly mounted on the cabinet shelf
comprises two fans, the evaporator, the air duct and a
water retaining tray placed under the evaporator.
The C.P.U. board (central processing unit) located in the
lower right section inside the vending machine controls
thedifferentfunctions andcommunicateswiththeC.P.U.
board of the master machine.
Thecoolingunitislocatedinthelower partof thecabinet.
Whenremovingthecoverofthelastventilationgrille(see
Fig.17) the air circulationensuresauniform temperature
inside the refrigerated box, between 9°C and 12°C.
When covering the ventilation grille, the temperature
inside the refrigerated box is differentiated between the
upperthreetrays(12°-16°C)andthelowerthreetrays(8°-
10°C).
Thecoolingunitis defrostedautomaticallyevery 6hours.
However, the timing is programmable.
Thepowersupplyunit,mountedinthelowersectionofthe
cabinet, contains the relay card which activates the com-
pressor, the protection fuses, the main switch, the trans-
former and the C.P.U. board.
MAIN SWITCH
Thepowersupplyunit(seeFig.27)isfittedwithamanual
switch that disconnects the power from the machine
electrical system,
except from the terminal board supporting the line
cable, the line fuses and from the same switch area.
Beforeremovingthecoverfromtheseparts(indicated
witha specific plate) it is necessary to disconnect the
external switch.
All operations which require the machine to be ener-
gised with the door open must be carried out by
qualifiedpersonnelwhoareawareofthespecificrisks
of such condition.
BANK CONFIGURATION
The machines are initially configured for operation in a
bank of machines, therefore the software must be set for
the necessary options.
After completing the connection between the machines
and to the power supply, switch on only the master
machine.
Access the master/slave function in the technician menu
andselect the type ofslave to define thenumber of digits
indicating the selection.
Two digits (XX) are advisable if the bank has only one
machine with numeric selection.
If there are two slaves, it is advisable to use three digits
(0XX, 9XX) for identifying the selection groups.
When switching on the slave regarding the choice made,
the master will communicate if the procedure was suc-
cessful.
If necessary, repeat the procedure to configure the sec-
ond slave, making sure not to configure two slaves the
same way.
The configuration must be defined every time the master
machine is initialised.
Should the configuration of a slave need to be changed,
accessthemasterfunctionthatindicatestheswitchedon
slaves as not configured.
After the configuration, it will be possible to access the
filler and technician menus of the slave from the master
machine.
When pressing the programming button on the master,
thesoftwarewillasktheusertoselectthetypeofvending
