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
