pressure switches, protections, magnet circuit breakers, etc.).
6.2 FIXED PROTECTIONS
Fixed protective devices consist of fixed perimeter shields, which are used to prevent external parts
from entering the equipment.
Danger
It is prohibited to re-start the appliance following maintenance without having correctly restores the
panels.
Visual Check
You should check the integrity of fixed panels and corresponding fixings to the frame, focussing in
particular on the protective panels.
6.3 ISOLATING THE ELECTRIC POWER SUPPLY
Before conducting any maintenance work on the equipment or part of it, it is necessary to section the
power supply that powers it.
Danger
In the event of maintenance operations in which the operator cannot prevent accidental closure of
the circuit by others, to totally disconnect the appliance from the mains electricity.
6.4 RESIDUAL RISKS
During design the manufacturer examined all the areas or parts at risk. Therefore, all necessary
precautions have been taken to prevent risks to persons and damage to the appliance.
Attention
Periodically check that all safety devices are operating correctly.
Do not remove the fixed guards.
Do not introduce objects or tools into the work area.
Although the appliance is fitted with the safety devices prepared, there are still some risks that
cannot be eliminated, but reduced via corrective actions by the final integrator and correct operational
procedures.

7. DISPOSAL OF WASTE MATERIAL
During normal operation, the appliance 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.
PROCEDURE FOR DISPOSAL and RECYCLING AT THE END OF APPLIANCE
LIFE SPAN (AUTHORISED BODIES)
• Switch off the equipment and unplug the power supply cable.
• Remove the lamps (if installed). These should be disposed of separately.
• Remove the power units and the electronic cards. These should be disposed of separately.
• 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.
• Remove all mobile parts (doors, sliding doors, glass parts, etc.) and group the various materials
according to their features.
• Check the type of refrigerant on the plate positioned inside the counter; extract the refrigerant and
dispose of it through authorised services.
• Disconnect the evaporator, the condenser, the compressor, the pipes and fans. These are made of
copper, aluminium, steel and plastic and should therefore disposed of separately.
• On removal of all guards and the various components from the frame, separate the different types
of material making up the appliance (plastic, sheet steel, polyurethane, copper, etc) and collect
them separately.
All recyclable materials and waste should be processed and recycled by professionals, in compliance
with the laws in 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 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 the crossed wheelie bin sign is not present on the appliance, it means that the disposal of the
product is not the manufacturer's responsibility. In this case, the Regulations regarding the disposal
of waste in force are valid.
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.

8. INSTALLATION
This manual supplies the information necessary for correct unpacking, procedures for
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 0and +40 °C.
The appliance 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 said operation the appliance MUST placed on the special pallet supplied.
Unpack the appliance 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).
8.2 INSTALLATION - POSITIONING - ENVIRONMENTAL CONDITIONS
Attention
A dry room that can be ventilated is the suitable location for the appliance's installation. There
should be a good air flow around the compressor/condensing unit. Therefore the area around the
unit should not be obstructed by boxes or other objects.
Position the appliance away from heat sources (radiators, stoves of all types, etc.) and away from
the effects of continuous currents of air (e.g. caused by fans, air conditioning vents, 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. 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 identification 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 fitted 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.
