INTRODUCTION & WARNINGS REGARDING R32 GAS
ATTENTION :
fire hazard
The refrigerant used in these air conditioners is a hydrocarbon R32. R32 is a so-called "environmentally friendly" gas
because it is chlorine-free and ozone-friendly. It is classified as a 2L gas, part of a group of low-flammability, odour-
less gases, which implies compliance with rules:
• Please read the manual before installation, operation and maintenance.
• Do not install the unit in closed, tightly sealed spaces.
• The unit should be installed in a well ventilated area.
• Do not turn off the circuit breaker unless you smell something burning, or when repairing, checking or cleaning the
unit. If not, a refrigerant leak cannot be detected.
• Do not use any means of accelerating the defrosting or cleaning process other than those recommended by the
manufacturer.
• Do not pierce or burn the appliance.
• If the appliance is installed, operated or stored in an unventilated room, the room must be able to prevent the
stagnation of any refrigerant gas leaks that could be ignited by an electric stove, oven or other ignition source and
cause a fire or explosion.
• The appliance must not be stored in a room in which sources of ignition are permanently present (e.g. open flames,
gas appliance or electric heating in operation).
• To avoid fire, explosion and injury, do not use the unit when harmful gases (e.g. flammable or corrosive) are
detected near the unit.
• Do not use benzine or thinner to wipe the unit. This could lead to cracks, electrical shocks or fire.
• The location where an air conditioner using R32 refrigerant is installed and maintained must be free from open fire,
welding, cigarette smoke, a drying oven or any other heat source at a temperature higher than 548°C that can easily
produce an open fire.
• Do not use any refrigerant other than that indicated on the outdoor unit (R32) for installation, relocation or repair.
The use of other refrigerants may cause operational disturbance or damage to the unit and result in personal injury.
• Beware of fire in the event of a refrigerant leak. A refrigerant leak can cause the air conditioner to malfunction (e.g.
if it does not generate cool or warm air). Contact the after-sales service. The refrigerant in the air conditioner is safe
and normally does not leak. However, in the event of a leak, contact with a burner, heater or cooker can result in the
generation of toxic gases. Stop using the air conditioner until a qualified person has confirmed that the leak has
been repaired.
• Do not attempt to repair, disassemble, reinstall or modify the air conditioner yourself, as this may result in gas
leaks, electrical shocks or fire.
• It is essential to carry out a safety inspection before servicing or repairing an air conditioner using combustible
refrigerant to minimise the risk of fire.
• Please contact your nearest service centre when maintenance is required. During maintenance, maintenance
personnel must strictly follow the maintenance instructions. Non-professionals are not allowed to service the air
conditioner. The refrigerant will need to be removed from during maintenance or when disposing of an air conditioner.
• People working or intervening in a refrigeration system must have appropriate certification, issued by an accredited
body, attesting to their competence in handling refrigerant gases in accordance with an officially recognised specifi-
cation.
• Repair work must be carried out in accordance with the manufacturer's recommendations. Maintenance and
repairs requiring the assistance of other specialists must be carried out under the supervision of a person special-
ised in the use of flammable refrigerant gases.
