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.
Do not use the appliance outdoors and do not leave it exposed to rain.

8.3 ELECTRIC CONNECTION

Attention

Check that the network voltage matches the one displayed on the identifi 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 fi 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

Earthing is necessary and mandatory by law.
