positioning and connection to mains electricity.
8.1 STORAGE and UNPACKING
The appliance, with or without the packaging, should be carefully stored inside warehouses or in areas away from the
elements and direct sunlight, at a temperature between 0 and +40 °C.
MAX
MIN
The movement of the apparatus should only be carried out using a pump or forked truck
of a sufcient capacity for the weight, and moved by qualied personnel: during such operations,
the apparatus must be positioned on the pallet supplied.
8.2 ENVIRONMENTAL CONDITIONS
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 local regulations.Please destroy "plastic" bags to
prevent them from becoming hazardous to children (suffocation).
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 inuence 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 sunlight; all of this causes the temperature inside the refrigerated compartment to rise
with negative consequences on operation and energy consumption. The apparatus must not be used outside
nor be exposed to rain.
8.3 ELECTRICAL CONNECTION
ATTENTION
Check that the network voltage matches the one displayed on the identication
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.
