During normal operation, the equipment does not generate any environmental

contamination. At the end of its life cycle, or if it is necessary to proceed to permanent

decommissioning, we recommend following the procedures below:

DISPOSAL (User)

The symbol, applied to either the product or its packaging, indicates that the product should

not be considered as normal domestic waste, but should be taken to a waste collection point

for the recycling of electrical and electronic appliances. The correct disposal of this product

helps to prevent potential negative consequences that might derive from inadequate product

disposal. For detailed information about recycling this product, contact your council, your local

waste collection service or the store where you purchased the product.

END-OF-LIFE DISPOSAL AND RECYCLING PROCEDURES

FOR THE EQUIPMENT (Authorised Bodies)

1. Switch off the equipment and unplug the power supply cable.

2. Remove the lamps (if installed). These should be disposed of separately.

3. Remove the control boards and the electronic cards. These should be disposed of

separately.

4. Remove all the independent parts (grids, casings, proﬁles, etc.) and group them

according to shared features in order to access the heat exchangers, pipes, cables, etc.

and be careful not to damage the cooling circuit.

5. Remove all mobile parts (doors, sliding doors, glass parts, etc.) and group the various

materials according to their features.

6. Check the type of coolant on the label located inside the counter. Remove the coolant

and dispose of it through authorised services.

7. Disconnect the evaporator, condenser, compressor, pipes and fans. These are made of

copper, aluminium, steel and plastic and should therefore disposed of separately.

8. Once all the guardings and the various parts of the frame have been removed, separate

the various types of material they are made from (plastic, metal sheets, polyurethane,

copper, etc.) into groups according to their features.

All recyclable materials and waste should be processed and recycled by professionals, in

compliance with the laws of the country in question.

The company responsible for recycling the materials should be registered and certiﬁed as a

waste disposal service in accordance with the speciﬁc directives of the country in question.

Attention

Illegal disposal of the product by the owner will result in administrative sanctions as required by cur-

rent laws.

Disposal of the product should comply with current laws on the disposal of coolant liquids and mineral

oils.

Important

If there is no symbol representing a barred dustbin on the equipment, this means that the manu-

facturer is not responsible for taking care of the disposal of the product. In this case, again, current

waste disposal laws should be complied with.

Additional information

Further information on the disposal of liquid coolant, oils and other substances is available on the safety

data sheet corresponding to the substance itself.

or in areas away from the elements and direct sunlight, at a temperature between 0and

+40°C.

The equipment should only be moved by qualiﬁed 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 ﬁxing 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 ﬂow around the compressor and condensing unit. Therefore the area

around the unit should not be obstructed by boxes or other objects.

Position the equipment away from sources of heat (radiators, all types of ovens, etc.), and away from

draughts (generated for example by fans, air conditioning ducts, etc.).

Also avoid direct exposure to sunlight, or anything that causes the temperature inside the cabinet to

rise with detrimental results to unit operation and energy consumption. 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

identiﬁcation 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 the

compressor is started.

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 electrical system socket must be ﬁtted with a disconnecting device from the mains (rated for the

load and conform to current standards) to guarantee full disconnection in overloads category III (3)

and ensure protection of the circuits from earth faults, overloads and short circuits.

Do not route the electricity cable in passageways.
