Materials and fluids used
• R290 gas is potentially flammable and explosive. Take every possible precaution to prevent any risk linked to the nature of this
gas during any routine and/or extraordinary operation carried out on the appliance.
• In appliances using R-744 as refrigerant, the design pressure is 14 MPa (140 bar).
WARNING: the refrigeration system is under high side pressure. Do not tamper with it. Contact qualified service personnel before
disposal.
A.8
Climatic Class
Climatic Class
The climatic class given on the data plate refers to the following values:
• Fully insulated door models:
Climatic Class 5:
– 43℃ (IEC/EN 60335-2-89)
– 40℃ room with 40% relative humidity (EN 16825/EN ISO 22041).
• Glass door models (1MTN):
Climatic Class 5:
– 43℃ (IEC/EN 60335-2-89)
– 30℃ room with 55% relative humidity (EN 16825/EN ISO 22041).
• Glass door models (1MBT-2MTN):
Climatic Class 5:
– 43℃ (IEC/EN 60335-2-89)
– 25℃ room with 60% relative humidity (EN 16825/EN ISO 22041).
A.9
Transport, handling and storage
• Transport (i.e. transfer of the machine from one place to another) and handling (i.e. transfer inside workplaces) must occur with
the use of special and adequate means.
• Do not stand under suspended loads during loading or unloading operations. Unauthorized personnel must not enter the work
area.
• The weight of the appliance alone is not sufficient to keep it steady.
• For machine lifting and anchoring, do not use movable or weak parts such as: casings, electrical raceways, pneumatic parts, etc.
• Do not push or pull the machine to move it, as it may tip over. Use proper tool to lift the machine.
• Arrange a suitable area with flat floor for machine unloading and storage operations.
• Machine transport, handling and storage personnel must be adequately instructed and trained regarding the safely use of lifting
systems and personal protection equipment suitable for the type of operation carried out.
A.10 Installation and assembly
• The installer must evaluate the minimum volume of the installation's environment necessary to reduce the risks related to danger
caused by the flammability and toxicity of the refrigerant present in the appliance.
• The operations described must be carried out in compliance with the current safety regulations and provisions in force in the
country of use.
• The appliance is not suitable for installation outdoors and/or in places exposed to atmospheric agents (rain, direct sunlight, etc.).
A.11 Electrical connection
• The power supply system must be suitable for the rated current of the connected appliance; the connection must be carried out in
compliance with the regulations and provisions in force in the country of use.
• For appliances with remote unit, the connection must be made separately for the unit and the appliance.
• The information regarding the appliance power supply voltage and frequency is given on the data plate.
• Install between the power cable and the electric line a differential thermal-magnetic switch suitable for the absorption specified
on the data plate, with contact gap enabling complete disconnection in category III overvoltage conditions and complying with the
regulations in force.
For the correct sizing of the switch or plug, refer to the absorbed current specified on the appliance data plate.
• After making the connection, with the appliance running check that the power supply does not fluctuate by ±10% the rated
voltage.
• With models arranged for operation without incorporated refrigerating system, carry out the condensing unit and solenoid valve
electrical connections as shown in the wiring diagram accompanying the appliance. The connection must be made with a cable
of suitable section. Insert and secure the cables with the special cable clamp. Correctly connect each wire to the corresponding
terminal.
• If the power cable is damaged or too short, it must be replaced by the Customer Care Service or in any case by specialised
personnel, in order to prevent any risk.
• The manufacturer declines any liability for damage or injury resulting from breach of the above rules or non-compliance with the
electrical safety regulations in force in the country where the appliance is used.
A.12 Maximum impedance permitted
The following models have to be connected to a public distribution system having a maximum permissible system impedance as
shown in the table:
