4. INSTALLATION
This manual provides information on how to correctly unpack the equipment, the
procedures to
position it and describes how to connect the equipment to the electric network.
4.1 Storage and unpacking
The equipment, 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.
The equipment should only be moved by quali! ed personnel operating forklift trucks, the
power of which should be suited to handling the weight of the product: during this operation
the equipment MUST be placed on the special pallet supplied.
Unpack the equipment by removing the screws ! xing it to the pallet.
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).
4.2 Installation, positioning and ambient conditions
Attention
There should be a good air # ow around the compressor and condensing unit. Therefore the area
around the unit should not be obstructed by boxes or other objects.
Position the equipment far from sources of heat (radiators, stoves of any kind, etc.) and far from the
in-# ux of continuous air (caused for instance by fans, air-conditioned inlets, etc.).
Avoid also exposing the equipment to direct sun rays. All of these factors cause the temperature inside
the refrigerated compartment to rise with harmful consequences for the equipment's functionality and
costly consumption of energy. Do not use the equipment outdoors and do not leave it exposed to rain.
4.3 Electrical connection
Attention
Check that the voltage indicated on the appliance is the same as the value on the appliance
identi! cation label and in the table provided in paragraph 2 of this manual, and check that the
required voltage is suitable.
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 socket of the plant must have a device to disconnect it from the power network (sized to ! t
the load and compliant with the current legislation) which guarantees complete power cut-off in
conditions of overvoltage III (3) and which must therefore protect the circuits against grounding
failures, overloads, and short-circuits.
Do not route the electricity cable in passageways.
Attention
Earthing is necessary and mandatory by law.
