1.3
Electrical wiring
General
The appliance must be installed in accordance with national wiring regulations. Capacity shortages in the
power supply circuit or an incomplete installation may cause an electric shock or fire.
Precautions
Use wiring that meets the specifications in the installation manual and the stipulations in the local regula-
tions and laws. Use of wiring which does not meet the specifications may cause electric shocks, electrical
leakage, smoking and/or a fire.
Always connect a protective earthing cable (grounding). Earthing must comply with the prevailing installa-
tion standards. Earth the appliance before making any electrical connections. Incomplete grounding can
cause a malfunction or electric shock.
To avoid electric shock, make sure that the length of the conductors between the strain relief device and
the terminal blocks is such that the active conductors are put under tension before the earth conductor.
Install a circuit breaker that meets the specifications in the installation manual and the stipulations in the
local regulations and laws.
Install the circuit breaker where it can be easily accessed by the technician.
In order to avoid the danger of an unexpected thermal circuit breaker reset, this appliance must not be
powered through an external switch, such as a timer, or be connected to a circuit which is regularly
switched on and off by the electricity provider.
If a power supply cable comes with the appliance and it turns out to be damaged, it must be replaced by
the manufacturer, its after sales service or persons with similar qualifications in order to avoid danger.
When connecting the appliance to the electricity mains or carrying out any other wiring work, refer to the
instructions given in the installation manual and the provided wiring diagrams.
Separate the very low voltage cables from the 230/400 V power supply cables.

About R32 refrigerant
This product contains fluorinated greenhouse gases.
Precautions
Do not vent gases into the atmosphere.
When installing, relocating, or servicing the air conditioner, only use the specified refrigerant (R32) to
charge the refrigerant lines. Do not mix it with any other refrigerant and do not allow air, liquids or other
gases to remain in the lines.
General
Maximum allowable refrigerant charge according to the technical data in this manual.

Warning
Only a qualified installer or qualified service person are allowed to carry out the
electrical work of the indoor and outdoor units. Under no circumstances must this
work be done by an unqualified individual since failure to carry out the work properly
may result in electric shocks and/or electrical leaks.
Danger
Before any wiring work on the electrical circuit, switch off the power supply, check
that no voltage is present and secure the circuit breaker with a circuit breaker lock-
out.
Warning
Do not use means to accelerate the defrosting process or to clean, other than
those recommended by the manufacturer.
The appliance shall be stored in a room without continuously operating ignition
sources (for example: open flames, an operating gas appliance or an operating
electric heater).
Do not pierce or burn.
Be aware that refrigerants may not contain an odour.
Warning
The refrigerant inside the unit is flammable and toxic. If the refrigerant leaks in the
room and comes in contact with fire from a burner, a heater, or a cooker, it may
result in fire or the formation of a harmful gas. When a leak is detected, turn off
any combustible heating devices, ventilate the room and contact the dealer from
which you purchased the unit.
Do not use the unit until a qualified installer confirms that the section from which
the refrigerant leaked has been repaired.
