USE OF THE CAN & BOTTLE
VENDING MACHINE

Can & bottle vending machines should only be used to sell
and dispense drinks contained in factory-sealed cans and
bottles made of different materials (such as metal, glass,
plastic. etc.).

Strictly comply with the manufacturer's specifications
regarding storage and expiry date for each product.

Any other use is incorrect and thus potentially dangerous.

INTRODUCTION

This technical documentation is a part and parcel of the
vending machine.

Therefore it must always follow the machine when it is
moved or ownership is transferred, so that different
operators may be able to consult it.

Before installing and using the machine, it is first necessary
to carefully read and understand the instructions contained
in this manual, as they offer important information for safe
installation, use and maintenance.

This manual is divided into three sections.

The first section describes the loading and routine cleaning
operations which are carried out in areas of the machine
accessible with the sole use of the door key, without using
any other tools.
The second section contains the instructions for correct
installation and all information necessary for optimum use
of the machine.
The third section describes the software programming.

The operations described in the second and third
sections must be carried out exclusively by personnel
who have a specific knowledge of the machine func-
tions from a point of view of electrical safety and health
regulations.

IDENTIFICATION OF THE VENDING
MACHINE AND ITS CHARACTERISTICS

Every machine is identified by its own serial number,
indicated on the rating plate attached inside the cabinet on
the right hand side.
This plate (see Figure 2) is the only one acknowledged by
the manufacturer as identification of the machine, and
carries all data which readily and safely gives technical
information supplied by the manufacturer. It also assists in
the spare parts management.
It is therefore recommended that this plate be neither
damaged nor removed.

POSITIONING THE VENDING MACHINE

The vending machine is not suitable for outdoor installation.
It must be positioned in a dry room where the temperature
remains between 2° C and 32° C, and not where water jets
are used for cleaning (e.g. in large kitchens, etc.).

The machine should be placed away from heat sources
and close to a wall, so that the back panel is at a
minimum distance of 10 cm from it and correct ventila-
tion may be ensured, especially in the compressor
area.

The machine should never be covered with a cloth or
the like.

The machine should be positioned in such a way that it has
a maximum inclination of 2°.
If necessary provide proper levelling by way of the adjust-
able feet included.
Should it become necessary, it is possible to secure the
machine to the floor.
Pre-drilled holes at the bottom of the machine are posi-
tioned as indicated in the drawing below:
Alternatively the machine can be secured to a wall by
means of the special spacer kit ,available as an accessory,
to be fixed to the top of the cabinet.

WARNING FOR INSTALLATION

Installation and the following maintenance operations
should be carried out by qualified personnel only, who
are trained in the correct use of the machine according
to the standards in force.

The machine is sold without a payment system, therefore
the installer of such a system has sole responsibility for any
damage to the unit or to things and persons caused by
incorrect installation.

The integrity of the vending machine and its conformity
with the rules and regulations in force for its relevant
systems must be checked by qualified personnel at
least once a year.

PRECAUSIONS IN USING THE MACHINE

The following precautions will help protecting the environ-
ment:

- use biodegradable products only to clean the machine;

- adequately dispose of all containers of the products

used for loading and cleaning the machine;

- keep the machine away from heat sources;

- regularly check the condition of the door seal to limit

heat transfer to a minimum;

- limit as much as possible door opening time during

loading operations to avoid temperature increase inside
the cabinet and subsequent increase in power con-
sumption.

WARNING FOR SCRAPPING

Whenever the machine is to be scrapped, the laws in force
regarding environment protection should be strictly ob-
served, more specifically:

- ferrous and plastic materials and the like are to be

disposed of in authorized areas only;

- insulating materials should be recovered by qualified

companies.

- the gas inside the cooling unit, regardless of the type

(see the identification plate), should be recovered by
qualified companies by means of special equipment.

CAUTION

When completely filled, the machine has a total static
weight, bearing on the 4 support feet, that varies
between 500 and 700 Kg according to the model.

Therefore, the structure on which the machine stands
must suitable for supporting such weight to avoid any
hazardous conditions, like collapsing, sinking, other
damage or any possible instability.

VARIABLE COMBINATION LOCK

Some machine models are fitted with a variable combina-
tion lock.
The lock is supplied with two silver colour keys to be used
for normal opening and closing.
The lock can be customised by using a kit, available as
accessory, which permits the combination of the lock to be
changed.
This kit includes a change key (black) for the current lock
combination as well as the change (gold) and use (silver)
keys for the new combination.
Sets of change and use keys with other combinations can
be supplied on request.
Additional sets of use keys (silver) may be requested,
indicating the combination stamped on the keys.
Generally, only the use key (silver) is used, while the
combination change keys (gold) can be kept as spares.

Do not use the change key for normal opening, as it may
damage the lock.

To change combination do as follows:

- insert the current change key (black) and rotate to the

change position (reference notch at 120°);

- remove the current change key and insert the new

change key (gold);

- rotate to the close position (0°) and remove the change

key.

The lock will now have the new combination.

The keys with the old combination cannot be used for
the new combination.

LOADING AND CLEANING

DOOR SWITCH

When opening the door a special micro-switch disconnects
the power from the electrical system of the machine, to
allow the loading and routine cleaning operations described
below in full safety.

All operations requiring the machine to be energised
must be carried out EXCLUSIVELY by qualified per-
sonnel, aware of the specific risks of such condition.

3 - Adjustable thermostat

DISPENSING MODULES

To get the best possible use of the machine based on the
available internal space, the number of selections and the
size of the dispensed products, the machines belonging to
this range can be equipped with three different types of
dispensing devices, i.e.:
- a dispensing module for cans;
- single columns;
- double columns.
Each machine can have a dispensing module for cans and
a variable number of columns according to the model.
Each device is set to dispense only one type of product with
precise dimensional characteristics.

Before loading the machine, it is therefore essential to
know exactly the type of product for which the device
was set.

DISPENSING MODULE FOR CANS

(where installed)

The module (toboggan), installed on the left hand side of the
machine, is used to dispense four different types of drink
and can be adjusted for 250, 330 or 355 cc cans.
The selections, from top to bottom, coincide with the order
of the first four selection buttons and have a maximum
capacity of:
- 25 cans for the first selection
- 23 cans for the second selection
- 19 cans for the third selection
- 15 cans for the fourth selection

-------------------------------------------------------------------------------------------------------------------------------------------------------------

If a single column, a plastic diaphragm, hooked to the
upper side of the column.
In order to correctly load the column, do as follows:

- release the diaphragm by lifting it by its grip;

- load some bottles in the back row (to half height) and

position the diaphragm against it;

- load the bottles in the front row;

- complete loading of the back row and re-hook the

diaphragm .

- complete loading of the column.

After completely loading the machine:

- close the retaining gate:

- after all loading operations make a test selection for

each product.

All loading operations must be carried out as quickly as
possible, to limit as much as possible the increase of
temperature inside the refrigerated box and therefore
power consumption.

3 - Diaphragm hook

TEMPERATURE CONTROL

The thermostat is initially adjusted so that a temperature of
+1.5°C is maintained in the lower portion of the refrigerated
box (containing bottles and cans which will be sold first).
The thermostat is located next to the refrigerating unit (see
Fig. 5).
To change temperature, turn the thermostat knob keeping
in mind that the temperature is approximately:

position “7”

= + 1,5°C

position “1”

= + 5°C

position “OFF”

= Switched off

RELEASING A COLUMN

It may occur that, for any reason, the products are jammed
in the dispensing area.
In this case, to restore the full functionality of the jammed
column, do as follows:

- manually empty the concerned column, being sure that

the rotor area is clear;

- move minidip 6 on the control card (see Fig. 14) to

position ON.

ROUTINE MAINTENANCE

Before any cleaning or maintenance operations, discon-
nect the machine from the mains power supply.

Under no circumstances should sprayed water be used
to wash the machine.

MAINTENANCE TO THE COOLING UNIT

Condensed water within the refrigerated box is drained into
the cup placed in the compressor compartment, and then
it evaporate because of the heat generated by the con-
denser coil.
However it is advisable to periodically check that there in
not excessive water in the cup; in this case check for any
cracks or loosening of the refrigerated box seals.

- Periodically, or in the case of product breakage, the

cup must be cleaned to prevent mould and unpleasant
odour.

- Ensure that there is no buildup of dirt between the

condenser blades (brush the front part regularly) as this
may lead to poor air suction resulting in rapid reduction
of cooling performance.

- Do not use sharp tools to clean the evaporator or the

condenser.

Do not place any products in the area around the evapora-
tor, as this would hinder the flow of cold air, which must be
allowed to flow freely, otherwise ice may build up on the
evaporator surface.

PERIODICAL CLEANING

Clean the galvanised parts and the anti-friction elements
(see Fig. 10) with lukewarm water and mild detergent; then
rinse thoroughly and wipe dry carefully.

When cleaning metal parts DO NOT use any detergent
containing abrasive or corrosive agents; do not use
common steel wool, wire brushes or steel scrapers.

SUSPENDING FROM USE

In the case of failure or malfunction switch the machine
off.

If for any reason the machine should remain switched off for
a period of time exceeding the use-by date of the products,
or anyway for a long time, take the following precautions:

- disconnect the plug from the power outlet;

- remove all products from the columns and clean the

inside and all accessories.

INSTALLATION

The machine installation and the following maintenance
operations should be carried out with the machine ener-
gised and therefore exclusively by qualified personnel, who
are trained in the correct use of the machine and aware of
the specific risks of such condition.
To energise the electrical system of the machine with the door
open, simply insert the special key into the door switch (see
Fig. 5).

The dispensing motors remain disconnected, thanks
to the special switch (see Fig. 5), even with the key
inserted.

This is to avoid the risk of accidental injury.

The rotors must be electrically operated with the door
closed.

Energised parts cannot be accessed with the door
open. Only those parts inside the machine with protec-
tive covers, and carrying the message "disconnect
electricity before removing the protective cover", re-
main energised.

Before removing such protective covers, the external
switch must be disconnected.

The door can be closed only after removing the key from the
door switch.

The machine must be installed in a dry room where the
temperature remains between 2° C and 32° C.

The relative humidity must not exceed 65%.

UNPACKING THE VENDING MACHINE

After removing the packing, ensure that the machine is
intact.
If the vending machine is found to be damaged, immedi-
ately inform the carrier and 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.

If the vending machine had been laid down during
transport, allow at least one hour before connecting it
to the mains.

The machine is supplied with a door stop chain secured only
on the door side
At installation the chain must be secured also on the
cabinet side, adjusting the length according to the space
available.

INSTALLING THE PAYMENT SYSTEM

The machine is sold without payment system, therefore
the installer of such a system has sole responsibility for
any damage to the machine or to things and persons
caused by incorrect installation.

- Fit the coin mechanism and make sure that the selec-

tor coin inlet and the coin return lever are aligned with
the coin chute and the selector opening cam;

- according to the type of coin mechanism, to achieve

such alignment move the plastic inserts in the adjacent
openings;

- ensure that all relevant parameters are programmed

correctly.

CONNECTING THE MACHINE
TO THE POWER SUPPLY

The machine is designed to operate under single-phase 230
V~ voltage and is protected by 10 A fuses.
Before making the connection ensure that the rating corre-
sponds to that of the power grid, and more specifically:

- the supply voltage rating should be within the range

recommended for the connection points;

- the main switch should be suitable to withstand the

peak load required, and at the same time should
ensure proper omnipolar disconnection from the
power grid with an opening gap of the contacts of at
least 3 mm.

The main switch, the power outlet and the plug should
be located within easy reach.

The electrical safety of the machine is ensured only when
it is correctly earthed according to the safety standards in
force.

This fundamental safety requirement must be duly verified,
and if in doubt the system must be carefully tested by quali-
fied technicians.
The power cable must be fitted with a fixed plug.
Any replacement of the power cable should be made by
qualified and suitably trained personnel only using cables
type HO5 RN-F, HO5 V V-F or H07 RN-F with a 3x1.5 mm

section.

Do not use adapters, multiple sockets and/or exten-
sions.

THE MANUFACTURER DECLINES ALL RESPONSIBIL-
ITY FOR ANY DAMAGE CAUSED BY NONCOMPLI-
ANCE WITH THE ABOVE MENTIONED PRECAUTIONS.

CONFIGURATION OF THE
DISPENSING MODULES

Should it be necessary to change the size of the products
to be dispensed, the dispensing modules for cans or the
columns (single and double) can be reconfigured by using
some elements available as optional.

The machine is supplied with a table containing details
of the settings as determined by the manufacturer
during tests and experiments performed with the most
common product types.

Settings for other product types can be determined by
following the information indicated below.

In any case it will be necessary to test each module to
be sure of its correct operation.

Products which are too irregular or not firm enough may not
be suitable for automatic dispensing.

DISPENSING MODULES FOR CANS

The modules can be adapted for dispensing 250, 330 and
355 cc cans by simply replacing the guides fitted at the inlet
of the two upper chutes with others which are adequately
sized.
The guide has the function of preventing the cans from
rotating and getting into a transverse position.
The guides are secured to the left hand wall of the module
(see Fig. 6) and are fixed with only one screw.

COLUMNS

The columns can be adapted for dispensing:

- 62 to 73 mm dia. bottles with 246 to 285 mm height in

a single row;

- 62 to 73 mm dia. bottles with 196 to 246 mm height in

a double row;

- 66 mm dia., 250 cc - 330 cc - 355 cc cans in quadruple

row.

The following procedure must be adopted.

According to the type of bottle it will be necessary to
make some adjustments to the settings indicated be-
low.

To adjust a column for dispensing a certain product, the
type and position of the following elements must be checked:

- rotor insert and side spacer, according to the product

diameter;

- product side support and motor cam, according to the

number of rows and to the product height;

- anti-friction elements and column backing, according to

the number of rows and to the product height;

- if the bottles have a long tapered neck, the positioning

of the bottle guides;

- for cans only, correct position of anti-theft plates.

ROTOR INSERT AND SIDE SPACERS

According to the diameter the appropriate rotor insert and
side spacers must be fitted.
The side spacer can be identified by the its dimension (see
Fig. 16).
Rotor inserts and side spacers are available for the follow-
ing diameters:

62-63-64 mm.

65-66-67 mm.

68-69-70 mm.

The rotor insert can be identified by the dispensed product
diameter printed on the element.
To install or replace the rotor insert and the spacers it is
advisable to remove the rotor from the machine, proceeding
as follows:

- undo the screws securing the release motor and extract

the assembly;

- push and extract the insert from the rotor;

- replace the insert and apply pressure to fit it into the

rotor, ensuring that it is properly secured in all points;

- to adjust the rotor for dispensing cans in four rows, it

is necessary to insert three anti-theft plates into the
special slots (see Fig. 17). The plates stop the cans
from sliding in the rotor when this is partially empty.
The plates must inserted into the slots B-D-E for 250
cc cans and into the slots A-C-E for 330 and 355 cc
cans.

There is no need for inserts or side spacers for products
with 71-72-73 mm diameter.

To dispense 62-mm diameter glass bottles from single
columns, it may be necessary to fit adapting plates as
indicated in the figure.

- insert the new spacer in the special slots located on

the left end of the column.

ANTI-FRICTION ELEMENTS

The anti-friction elements are frames made of special
plastic material which facilitate product sliding.
For dispensing bottles the anti-friction elements are fitted
on the double column baffles and on the corresponding left
hand wall.
The anti-friction elements are not necessary for single
columns or for dispensing cans.
Four anti-friction elements are used for each double col-
umn. According to the height of the bottles and to the
number of rows, they are installed as indicated in Fig. 21,
using the slots on the baffle.

The cam slots must be closed with the removable inserts
fitted on the cam as indicated in Fig. 20.

PAYMENT SYSTEMS

Interface with "Executive" coin mechanism

Connect the coin mechanism to the 15-pin molex power
supply connector and to connector CN1 on the control board.
Set the board as described in the "Programming of param-
eters and prices" section.
Set the two minidips (SW2) to OFF position.

Interface with MDB coin mechanism

Connect the coin mechanism to connector CN2 and ener-
gise the board with 24 V ac through connector CN19 using
the special cable. Set the board as described in the
"Programming of parameters and prices" section.
Set the two minidips (SW2) to ON position.

Interface with 24 Vvalidator

The validator must be connected to connector CN5 on the
board (see Fig. 27). Set the board as described in the
"Programming of parameters and prices" section.

Free vend for all selections

Place minidip 5 into position “ON”.

MINIDIP FUNCTIONS

Each of the 6 minidip (SW1), when moved to position "ON",
activates one of functions indicated below.
The two SW2 minidips have the following functions:
1-2 ON = payment system MDB
1-2 OFF = payment system Executive

1 - ON = Programming of parameters and sales prices
2 - ON = Reading on the display the stored data
3 - ON = Not used
4 - ON = Total sales display
5 - ON = Free vend
6 - ON = Motor reset

Motor reset

When one or more selections are blocked and the motor
cams are out of position, placing minidip 6 into position
"ON" automatically resets all blocked motors.
When a selection is blocked, the corresponding button is
illuminated.
When pressing the illuminated button, the display indicates

if the cause of the blockage is an empty module

and

if the cause is a problem connected with the

motor or with the micro-switch of that column.

Instant display of total sales

Placing minidip 4 into position "ON" causes the total sales
information to be shown on the display, thus skipping the
normal "data" procedure. After storing this value, minidip 4
must be placed back to position "OFF".

Automatically unloading the columns

Simultaneously placing minidip 4 and 6 into position "ON"
enables the function used to automatically unload the
columns.
After closing the door the message

will be

displayed; pressing the button of the selection to be
emptied causes the release motor to be activated at
intervals of five seconds and up to 30 consecutive selec-
tions maximum.

The motor will continue for other four selections after the
signal of "empty" condition.
The automatic unload function can be interrupted by
pressing any button during the 5 second interval between
two releases.

PROGRAMMING OF PARAMETERS
AND PRICES

Place minidip 1 into position "ON".
The indication

will be displayed.

Now the last four selection buttons are illuminated and are
given the following functions:

Decimal point.
"x" is the number of the display digit (1-4) where the
decimal point is shown. With x=1 this point is not displayed;
to have two decimal digits displayed, enter x=3. In serial
operating mode also this information is transmitted directly
to the control board.

Ux - coins accepted by the validator.
This function is used only when the control board is
interfaced with a coin validator.
Multiply the basic coin value by "xx", to assign the value to
the six coins. For example, if the basic coin is set to 1 (Sc
1):

(1st coin)

U1 x=5

5x1

= 0.05

(2nd coin)

U2 x=10

10x1 = 0.10

(3rd coin)

U3 x=20

20x1 = 0.20

(4th coin)

U4 x=50

50x1 = 0.50

5th coin)

U5 x=100

100x1 = 1.00

(6th coin)

U6 x=200

200x1 = 2.00

Credit mode (validators only)
This function is used to make available to the user any
amount exceeding the selection price
0 = excess cashed
1 = excess made available
2 = excess made available for a programmed time; confirm
this option to access function

which allows

programming of such time for up to a maximum of 99
seconds.

Maximum credit (only validators and MDB )
The maximum credit (expressed in number of basic coins)
accepted by the coin mechanism is displayed . If such
value is set to 0 this function is ignored.

Sales prices per selection.
"xxxx" is the price value of a selection; the selection button
to which the price is referred is illuminated. The maximum
value is 255 times the basic coin (ex. Sc = 1, Max price =
1*255 = 2.55).

Maximum change (MDB only)
It is the value of the maximum amount of change returned.
If set to 0 the maximum possible value is returned.

Multiple sales (MDB only)
This function is used to make available to the user any
amount exceeding the selection price.
0 = change returned after each selection
1 = change returned only after pressing the button

Accepted coins (MDB only)
The MDB protocol allows acceptance of 16 coins:
XX = 1 to 16
Y = 0 = disabled
Y = 1 = enabled
The actual number of usable coins depends on the coin
mechanism installed.

Machine code
The machine is identified by a 6-digit code, useful in the
case of automatic data collection.
"x" is the value (0 to 9) which can be assigned to the digits
(1 to 6).

Counters display
This function enables the possibility of displaying or not the
total selection counter when switching the machine on.
x=0

Function disabled

X=1

Function enabled

Control of cycle start time.
This function is not used for this machine, therefore it
MUST be set to ZERO.

Time-out.
It controls the maximum operating time (expressed in
seconds) of the dispensing motors. If such time is ex-
ceeded, the control board stops the motor and switches the
appropriate "empty" warning lamp on. The "empty" condi-
tion is recorded and the selection is blocked until it is reset
(see paragraph "motor reset ").

Initialising
This function is used in the case of stored data error or when
replacing the EPROM. All statistical data will be reset.
Press the confirm button 3 and the prompt message

to confirm will be displayed.

Press again button 3 and initialising will start; press button
4 to cancel the initialising routine.

Place minidip 1 back to position "OFF" to return to the
normal operating mode.
