USING THE VENDING MACHINES OF
PACKED PRODUCTS
The control electronics of the machine enables you to
separately assign every single selection a dierent sales
price. The various functions are programmed by means
of the selection pushbutton-panel without adding any
specic equipment.
All models are equipped with variable-conguration trays
by adding or removing dividers, spirals and ratio-motors
in order to easily adapt the machine to one's own needs.
All trays are arranged for the operation of 6 selections
(maximum conguration).
The drawers are equipped with independent motors and
spirals, each selection will continue to work even if the
others are out of order.
POSITIONING THE VENDING MACHINE
The machine is not suitable for installation outdoors.
It must be installed in a dry room and far from any
source of heat at a temperature ranging from 5°C to
34°C. It can not be installed in a room where water jets
are used for cleaning (e.g. large kitchens, etc.).
The maximum inclination shall not exceed 2 degrees. If
necessary, level it by using the adjustable feet.
The ventilation system enables you to place the back of
the machine against the wall, thus saving space, since
air is aspirated from the bottom and discharged through
a grid of the feet cover.
Attention !!!
If not correct, ventilation can compromise the good
operation of the cooling unit.

VARIABLE COMBINATION LOCK
Some models are supplied with a variable combination
lock.
The lock is complete with a silver key, with the standard
combination, for normal opening and closing operations.
It is possible to customise the locks by using a kit made
available as an accessory and intended to change the
lock combination.
The kit is composed by a change key (black) of the cur-
rent combination as well as by change (gold) and use
(silver) keys of the new combination.
Sets of change and use keys with other combinations
can be supplied upon request.
Moreover, further sets of use keys (silver) may be re-
quested by specifying the combination stamped on the
keys.
Generally, only the use key (silver) shall be used where-
as the combination change keys (gold) can be kept as
spare keys.

BOTTLE TRAYS
These trays can be recognised by the presence of a
retainer bridge for each compartment.
These trays enable the machine to distribute:
- 0.33/0.5/0.6 litre plastic bottles
- 0.375 / 0.5 litre cans
- 0.25/0.33 litre "slim" cans
vertically, thus improving the readability of the product
label.

STANDARD TRAYS
sNack proDucts
- Extract one tray at a time by lifting and pulling it
The upper trays will tilt downwards to facilitate the load-
ing cycle.
- Load the products from the outside to the inside. Avoid
inserting any package at a temperature above 30°C.
Make sure that all spaces are filled The product bottom
must rest at the bottom of the compartment with the
label facing the glassfront so that it can be recognised.
All products shall be easily insertable between the
spirals. Avoid inserting any object that is too large.
- Push in the trays completely. Make sure that they go
past the retaining chute.
The sealed edge of bags may be caught under the
spiral, thus preventing the bag from falling down.
Fold it forwards and upwards before inserting it into the
spiral.
The most fragile products must be placed on the
lower trays to avoid any damage when falling down.
Particularly “narrow” products can be dispensed only by
using the special spacer

Load from the outside to the inside, vertically, with the
label facing the glassfront so that it can be recognised.
These products may require the use of raised supports.
Most bottles can be dispensed without any raised sup-
port, i.e. by loading the bottles up side down, so that the
cap slides in the drawer channel.
If you wish to dispense bottles up side down,
please arrange them in the 2/3 lower trays:
