The Refrigerant
•To realize the function of the air conditioner unit, a special refrigerant circulates in the system. The
refrigerant is the fluoride R32 = GWP (Global warming potential). This refrigerant is flammable
and inodorous. It can lead to explosions under certain conditions, however the flammability of
this refrigerant is very low and it can be ignited only by fire.
•Compared to other common refrigerants, R32 is a non-polluting refrigerant with no harm to the
ozonosphere and a lower effect upon the greenhouse effect. R32 has very good thermodynamic
features which lead to a really high energy efficiency. The units therefore need less filling.
Warning:
Do not try to accelerate the defrosting process or to clean the appliance in different ways other than those
recommended by the manufacturer. Should repair be necessary, contact your nearest authorized
Argoclima Service Centre. Any repairs carried out by unqualified personnel may be dangerous. The
appliance has to be stored in a room that doesn’t have any continuously operating ignition sources. (for
example: open flames, an operating gas appliance or an operating electric heater.) Do not pierce or
burn.
Appliance has to be installed, operated and stored in a room with a floor area larger than X m2. (Please
refer to table "a" in section of " Safety Operation of Inflammable Refrigerant" for Space X.)
For repairs, strictly follow manufacturer’s instructions only for appliances filled with R32 flammable gas.
Be aware that refrigerants do not have any odour.
Appliance filled with flammable gas R32.
Before using the appliance, read the owner’s manual.
Before installing the appliance, read the installation manual.
Before repairing the appliance, read the service manual.
