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 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, used and stored in a room with a floor area larger than 12 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.
Appliance is filled with flammable gas R290.
Before installing and using the appliance, read the
owner manual.
Before installing the appliance, read the installation
manual.
