HANDLlNGANDTRANSPORT
The equipment is packed on a wooden pallette suitable for lifting by fork lifts or
transpallette in order to avoid possible damages. Upon request or in case of par-
ticular transport requirements it could be packed in a wooden crate (photo A).
The wooden packing can be recycled. therefore it has to be disposed in the special
waste plan for recycling. It is advisable to use a wooden board for any handling of
the cabinet in order to avoid damages of the structure.
-Carefully unpack the unit. paying attention so as not to damage it or throw parts andl
or accessories (i.e. screws) away.

IMPORTANT INSTRUCTIONS AND SUGGESTIONS
Before using the equipment it is important to read these instructions carefully as
improper use can be dangerous. Before connecting the refrigerated unit, make sure
that the power supply voltage is as indicated on the label (photo C). The equipment
MUST be connected to a grounded power socket, in compliance with the current
legislation to satisfy the safety requirements.
For usage of the unit, as every electrical device, basic rules have to be followed:
-do not touch or plug the equipment with damp or wet hands or feet;
-do not pull the electric cable to unplug it;
-do not expose it to the atmospheric agents;
-do not allow children to use it without adult supervision;
-before starting any cleaning or maintenance operation. it is necessary
to unplug the equipment and do not attempt to make any modification. c
WORKING TEMPERATURE
This equipment is manufactured in conformity with the ambient conditions of
climatic class 3 (25° C -60% R.H.) EN 441-4. The refrigerated unit maintains its
performance characteristics with an ambient temperature and relative humidity of
no more than: +25°C and 60% R.H. ( relative humidity). In case the ambient condi-
tions are not included in the above mentioned ones. a lower performance must be
expected.
CLEANING
Before switching on the unit. clean the equipment thoroughly. both inside and out-
side. using warm water and a solution of bicarbonate of soda (I tea spoon every
2 liters) or white vinegar. Carefully dry the unit with a soft cloth. Never use metal
pads or abrasive substances. Never use sharp objects; any damage resulting from the
use of these objects will not be covered by warranty.
ElECTRICAl POWER I CONNECTION
First of ali. make sure that there is an efficient ground system in compliance with the
current legislation regarding electrical safety.When in doubt. request a careful check
from a qualified technician. The unit is equiped with the plug and the electrical cable
mod. Schuco (photo D).
I -verify that the power supply voltage is as indicated on the machine rate plate
(photo C -23OV SO Hz monophase)
2 .in case of incompatibility between the socket and the plug of the unit.
the plug should be replaced with a suitable one by a qualified technician
3 -do not connect any other appliance to the same power socket
4 -do not pull the electrical cable or the unit to unplug the equipment from the
socket (photo E)
S -pay attention that the power supply cable is laid in such a way as to prevent it
from being damaged or becoming hazardous to people and things.
THE MAIN POWER SUPPLY LlNE CAN BE ALTERED ONLY BY A QUALIFIED
TECHNICIAN.
6 -in case the power supply cable is damaged. it should be replaced only by a qua-
lified technician.
INSTALLATION
The refrigerated unit must be installed in a suitable dry piace and on a level f1oor.
to avoid an higher energy consumption and a shorter compressor life. It must be
installed on a level f1oor to prevent noise and bad working.

The refrigerated equipment should never be installed:
a -near sources of heat such as radiators. direct or indirect sunlight or other equip-
ment which produces heat (photo F);
b -in line with draughts coming from doors. windows or ajr conditioning systems
(photo F).
Do not close or obstruct the ventilation openings of the refrigeration unit. because
this would stop the airflow which cools the refrigeration unit causing a bad working.
OPERATION START
After the refrigerated equipment has been installed, the power supply voltage has
been checked and the plug has been connected, switch on the unit. When the unit
has reached the working tempe-
rature, put in the products alrea-
dy cooled. Do not exceed the
2/3 of the available room with
the product's level. Leave some
room between the displayed pro-
ducts in order to allow a good
airflow and never obstruct the
air intake situated on the front
side.

PERIODICAL IMAINTENANCEWe suggest to carry out a tho-
rough cleaning of the cabinet once
a month for the good working,
the good preservation of the food
and the aesthetics preservation of the equipment. The periodical cleaning can be made
by qualified people, who should know the procedures described in this paragraph.
ATTENTION! Before starting any cleaning operation it is necessary to turn off the
equipment by the on/off red switch and to unplug or disconnect the equipment by the
generai power security switch of your shop. During the whole cleaning operation we
suggest to use working gloves to protect your hand alI the time.
To carry out the cleaning it is necessary:
I -to remove ali goods from the refrigerated unit and to keep them in a freedge or in a
refrigerated ambient suitable for their preservation;
2 -to unplug or disconnect the main on/off switch, disconnect the plug from the power
socket and wait until the equipment temperature reaches the room temperature;
3 -carefully and thoroughly clean the display surface, the shelves, the glasses with spe-
cific cleaners for any surface. Never use abrasive substances, metal pads or other stuff
which can damage the unit.
4 -after every cleaning operation it is necessary to rinse with warm water and dry the
unit with a soft cloth; in case the smaller evaporation tray is full, it will have to be emp-
tied and then put again in its originai position.
To clean the condenser unscrew the screws of the front panel.
5 -use a dry paint brush and/or a vacuum cleaner, removing ali dust. Pay attention not
to bend or damage the fins, the tubes or the blades of the fans. Never neglect this ope-
ration, as it is basic for the good working of the unit and to avoid possible breakings.
When the cleaning operation is over, make sure that everything is clean and dry before
connecting the equipment to the power supply again.When the unit reaches the correct
working temperature, it is possible to reload it. In case of long absences (i.e. holidays,
etc.) the unit has to be unplugged, emptied completely, cleaned and dried.

TEMPERATURE
The thermostat. which is situated on the
electrical control panel. regulates the tem-
perature into the equipment and is usually
preset to +O/+6Co at the factory during the
testing phase.
A lower performance must be expected
from the refrigerated unit when:
-the equipment is set on the lowest tem- ' -,
perature
-the equipment is positioned in an ambient with higher temperature or relative
humidity than above indicated
-the amount of displayed products exceeds the maximum recommended and the pro-
per air circulation is prevented.
In those cases the goods are kept at higher temperatures. the refrigerating unit has
to run non-stop and ice may form on the evaporator. It is necessary therefore to
turn the equipment off (approx 24 hours) to allow the melting of the ice.
DEFROSTING
The defrosting takes piace automatically during the running of the unit. The defro-
sting cycles are 4 a day, last for about 40' each and are controlled by a timer in the
electrical control panel. During the defrosting phase the temperature of the unit
could be altered, but when this cycle is over, in a short time the working tempera-
ture will return to normal. The water from defrost is collected in a tray equipped
with automatic evaporation and a smaller tray underneath, which has to be emptied
manually when the automatic evaporation is not enough, especially during the sum-
mer months.
TECHNICAL ASSISTENCE (servicing)
If the equipment does not run properly or does not work at ali, in your own inte.
rest before calling for servicing, we suggest to check the following points:
-if the plug is well inserted in the socket;
-if the power reachs the socket to which the equipment is connected;
-if the thermostat is set as recommended;
-if the network voltage is the same as requested for the unit (+1- 6%).
DISMANTELLING OF EQUIPMENT
The demolition of the unit and the recovery of the component materials must be
carried out according to the regulation in force in this matter. Considering that the
equipment is formed by many different materials (i.e. ABS with polyurethane foam
for isolation. glass. stainless steel. aluminium. copper. etc.) and some of them are like
normal urban waste materials while other components. as refrigeration gas and oil.
MUST be given to a special recycling center.
REPLACEMENT OF LAMPS
Disconnect the main power supply before fitting or replacing the lamp. Slip the
ring nuts onto the fluorescent lamp. Fit the lamp in the lamphoder and turn it 90°.
Slide the ring nuts along the lamp until they rest on the lampholder and turn them
clockwise (NPP and NPQ); screw down tightly (NPW).
NIGHT-BLIND
In case that the wall-cabinet is equiped with a night-blind. we let you note that this
night-blind is self-blocking. there are no hooks to block it.The night-blind is equiped
with a spring and must always be pulled on. never left free. during the rolling phase.
The night-blind can be stopped in any position. according to one.s wish.
