indicated on the rating plate attached inside the cabinet on
the right side.
This plate (see Figure below) is the only one acknowl-
edged by the manufacturer and indicates all of the data
which readily and safely gives technical information sup-
plied by the manufacturer. It also assists in spare parts
management.
IN CASE OF FAILURE
In most cases, any technical problems are corrected by
small repair operations; however, before contacting the
manufacturer we recommend that this manual be read
carefully.
Should there be serious failures or malfunctions, contact
the following:

INTRODUCTION
This technical documentation is part and parcel of the
vending machine and must always follow the machine
in case it is moved or transfer of ownership, so as to
allow consultation by different operators.
Before starting installation and using the machine, it is first
necessary to carefully read and understand the instruc-
tions contained in this manual, as they offer important
information on installation safety, operating instructions
and maintenance.
This manual is divided into three chapters.
The first chapter describes the loading and routine main-
tenance operations which are carried out in areas of the
machine accessible with simple use of the door key,
without using any other tools.
The second chapter contains the instructions for correct
installation and all information necessary for optimum use
of the machine.
The third chapter describes maintenance operations
which involve the use of tools to access potentially danger-
ous areas.
The operations described in the second and third
chapters must be carried out only by personnel who
have the specific knowledge of the machine function-
ing from a point of view of electrical safety and health
regulations.
The vending machines in the Colibrì range are designed to
meet a wide spectrum of user needs.
This manual describes all possible machine configu-
rations and the related safety and maintenance in-
structions.
Nonstandard devices will be indicated as “optional”.

POSITIONING THE VENDING MACHINE
The vending machine is not suitable for outdoor installa-
tion. It must be positioned in a dry room where the tempera-
ture remains between 2°C and 32°C, and not where water
jets are used for cleaning (e.g. in large kitchens, etc.).
The machine must be placed on the special support
cabinet, which houses the liquid waste tray, the water
supply device, the payment system and, in the case of very
hard water, the softener cartridge.
The machine should be placed close to a wall, so that the
back panel is at a minimum distance of 4 cm from it and
correct ventilation may be ensured. The machine must
never be covered with cloth or the like.
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.
Important notice!!
Access to the machine interior for maintenance and/or
repairs is via the back panel.
Therefore the machine is designed to be rotated, thus
allowing removal of the back panel.
Installation on the cabinet
The machine must be placed on the special support
cabinet, which houses: the liquid waste tray, the water
supply kit, the payment system and, in the case of very
hard water, the softener unit.
WARNING FOR INSTALLATION
The machine installation and the following mainte-
nance 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 payment system, therefore
the installer of such system has sole responsibility for any
damage to the machine or to things and persons caused by
faulty installation.
The integrity of the machine and compliance with the
standards of the relevant systems must be checked at
least once a year by qualified personnel.
All packing materials shall be disposed of in a manner
which is safe for the environment.
PRECAUTIONS IN USING THE MACHINE
The following precautions will assist in protecting the
environment:
- use biodegradable products only to clean the machine;
- adequately dispose of all containers of the products
used for loading and cleaning the machine;
- switch the machine off during periods of inactivity, thus
achieving considerable energy savings.
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.

DOOR SWITCH
When opening the door a special switch disconnects the
power from the machine electrical system to allow the
operations described below, regarding filling and routine
cleaning.
All operations requiring the machine to be energized
should be carried out by qualified personnel ONLY,
informed about the specific risks of such situation.
MAINTENANCE AND DISINFECTION
According to current safety and health rules and regula-
tions, the operator of an automatic vending machine is
responsible for the hygiene and the maintenance of the
foodstuff circuits, to prevent formation of bacteria.
At installation the hydraulic circuits and the parts in
contact with foodstuff should be fully sanitised to
remove any bacteria which might have formed during
storage.
It is advisable that specific sanitising agents (such as
chlorine-based detergents or similar) are used for cleaning
also the surfaces which are not directly in contact with
foodstuff.
Some parts of the machine can be damaged by strong
detergents.
The manufacturer declines all responsibility for any dam-
age to persons caused by non-compliance with current
health regulations.
Before starting any maintenance operations requiring
parts of the unit to be removed, the machine must
always be switched off.
USING THE VENDING MACHINES OF HOT
DRINKS IN OPEN CONTAINERS
(Ex.: plastic cups, ceramic cups, jugs)
Vending machines for drinks in open containers should be
used only to sell and dispense drinks obtained by:
- brewing products like coffee and tea;
- reconstituting instant and lyophilised products;
These products should be declared by the manufacturer
as “suitable for automatic vending” in open containers.
The dispensed products should be consumed imme-
diately. They should never be preserved and/or packed
for later consumption.
Any other use is unsuitable and thus potentially danger-
ous.
