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 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 7 m
2
.
For repairs, strictly follow manufacturer’s instructions only for appliances filled with R290
flammable gas. Be aware that refrigerants do not have any odour.
