Electrical wiring

General

Only a qualified installer or qualified service person are allowed to carry out the electrical work of the in­

door 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.

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

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.

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 give rise to 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.

1.4 

Refrigerant safety

General

France: Pursuant to Article L. 113-3 of the French Consumer Code, the equipment must be installed by a 

certified operator whenever the refrigerant load is in excess of 5 tonnes of CO

2

 equivalent or when a re­

frigerant connection is necessary (the case with split systems, even when fitted with a quick coupling de­

vice).

All work on the refrigeration circuit must be done by a qualified professional, according to prevailing co­

des of practice and safety in the profession (recovery of the refrigerant, brazing under nitrogen). All braz­

ing work must be done by qualified brazers.

Precautions

Use only R410A refrigerant to fill the installation.

Use tools and pipe components especially designed for use with R410A refrigerant.

Use copper pipes deoxidised with phosphorus to carry the refrigerant.

Store the refrigerant connection pipes away from dust and humidity (risk of damage to the compressor).

Do not use a load cylinder.

Protect the heat pump components, including the insulation and structural elements. Do not overheat the 

pipes as brazed components may cause damage.

Contact between the refrigerant and a flame may result in emissions of toxic gases.

Do not touch the refrigeration connection pipes with your bare hands while the heat pump is running. 

Danger of burn or frost injury.

In the event of a refrigerant leakage:

Switch off the appliance.

Open the windows.

Do not use a naked flame, do not smoke, do not operate electrical contacts.

Avoid contact with the refrigerant. Danger of frost injuries.

Locate the probable leak and seal it immediately. Use only original parts to replace a defective refriger­

ation component.

Use only dehydrated nitrogen for detecting leaks or for pressurised tests.

Do not allow the refrigerant to escape into the atmosphere.
