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.
