11. INSTALLATION
All packaging materials are recyclable and should be disposed of in accordance with local regulations. All packaging materials
are recyclable and should be disposed of in accordance with the local regulations. Please destroy "plastic" bags to prevent them
from becoming hazardous to children (suffocation).
11.1 UNPACKING
STORAGE11.2
The appliance, with or without its packaging, must be carefully stored inside warehouses or in areas protected from the weather
and from direct sunlight, at a temperature of between 32 and 104 °F.
11.3 HANDLING
Handling of the equipment must be performed exclusively by a forklift truck of power adequate to the weight of
the same and operated by qualied personnel: during this operation the equipment must always be positioned
on the dedicated pallet supplied.
11.4 ENVIRONMENTAL CONDITIONS
ATTENTION
A dry room that can be ventilated is the suitable location for the appliance's installation. There should be a good air
ow around the compressor/condensing unit. Therefore the area around the unit should not be obstructed by boxes
or other objects. Place the equipment away from sources of heat (radiators, heaters of any kind, etc.) and far from
the inuence of continuous air movement (caused by fans, air conditioning units, etc.). If it is unavoidable to install
near a heat source, use a suitable insulating plate. Also avoid exposure to direct solar irradiation; all of this causes
the temperature inside the refrigerated compartment to rise with negative consequences on operation and energy
consumption. Do not use the appliance outdoors and do not leave it exposed to rain.
11.5 ELECTRICAL CONNECTION
ATTENTION
Check that the network voltage matches the one displayed on the identication plate of the appliance, and that the
power is adequate. Check on the socket that the power supply voltage provides rated voltage (±10%) when you start
up the compressor. The plug should be directly connected to the electrical socket. It is forbidden to connect the plug
to the socket by means of multiple socket extensions or adaptors. The plant power supply socket must be tted with
a disconnection device from the mains electricity (dimensioned to the load and in compliance with Standards in
force), which guarantees complete disconnection in category III (3) over-voltage conditions and therefore protects the
circuits against earth faults, overloads and short circuits. Do not route the electricity cable in passageways.
ATTENTION
Remember that earthing is necessary and is a requirement imposed by law.

In case of uncertain or no operation, before requesting the intervention of the Technical Assistance service
perform the following checks:
MALFUNCTION CAUSE SOLUTION USER TECHNICAL ASSISTANCE
THE EQUIPMENT
DOES NOT WORK
Blown protective fuse First nd the cause of the trip
of the switch, and then replace the new fuse.
The master switch is open Close the master switch.
The plug is not inserted Insert the plug.
Electrical black-out If the black-out should be prolonged, transfer the prod-
uct into an appropriate cold storage container.
THE TEMPERATURE
IS NOT SUFFICIENTLY
LOW
Evaporator(s) completely blocked with
ice Carry out an additional defrosting cycle.
Wrong temperature setting Set the appropriate temperature.
Equipment being struck by
currents of air or exposed to
direct or reected sunlight
Remove any draughts and prevent any direct or reected
sunlight.
Insucient air ow for
cooling to the condenser
Remove anything which could obstruct
the circulation of air through the condenser (sheets of
paper, cardboard, insucient slots in grille, etc.).
Internal fans not working
or damaged fans Replace the ventilators/fans.
Thermostat / Electronic control board
not ecient
Replace the thermostat/electronic control board.
If the electronic control board is used on appliances with
R290 coolant, it must only be replaced with an original
spare part supplied by the manufacturer. Replace the
temperature probes only after having ascertained which
of them is inecient.
Condenser unit blocked by dust
or dirt in general
Clean the condensing unit thoroughly.
The condensing unit in particular operating environ-
ments (e.g. presence of dust, presence of excessive
humidity, etc.) when the performance of the appliance
deteriorates requires careful cleaning.
Insucient refrigerant quantity
in the cooling system
Find the cause of the refrigerant loss and remove it; top
up the refrigerant load
if necessary having emptied
the system.
THE COMPRESSOR DOES
NOT START WORKING
OR WORKS FOR
VERY SHORT PERIODS
No electric power supply
to the appliance
Check if there is a power cut.
Close the various switches on the power supply line.
Power supply voltage
too low
Check that the mains voltage of the power supply cable
corresponds to the nominal value 115V +/- 10%.
Temperature set
too high
If the temperature is higher than the air temperature
in the display chamber, the compressor will not start. Set
a more suitable temperature if the current value is not
low enough.
Maximum pressure
switch intervention (if present)
Check the cause of the continuous interventions of the
maximum pressure switch such as: blocked air condens-
er, air condenser fan stopped, excessively high ambient
temperature, breakage of the pressure switch itself.
