The Refrigerant R290
• To realize the function of the air conditioner unit, a special refrigerant circulates in
the system. The refrigerant is the fluoride R290 = 3 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, R290 is a non-polluting refrigerant with no
harm to the ozonosphere and a no effect upon the greenhouse effect. R290 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
