An omnipolar switch is to be installed before the appliance, in compliance with the
current regulations applied in the country where the appliance is installed.
The electrical connection is carried out from the rear part.
The electrical mains cables must be correctly sized and selected based on the
installation conditions.
The 10kg models have 3m of single phase cable (3G 1,5mm²) with a SCHUKO type
plug.
The 20kg models have 3,5m of three-phase cable (5G 2,5mm²) without plug.
The grounding cable is to be directly connected to a good grounding system.
The guarantee will cease and the Manufacturer will not be liable for any damage
to appliances or operators arising from the non-compliance with the and tampering to any part of the

Carry out the following checkings:
1) Outside temperatures must be included between 15°C and 38°C.
2) Turn on the appliance and wait 30 minutes before the use if the external temperature is “low”.
3) Check power input
4) Carry out at least one full quick cooling cycle
