The Refrigerant
WARNING：
To realize the function of the air conditioner unit, a special refrigerant circulates in
the system. The used refrigerant is the fluoride R32, which is specially cleaned.
The refrigerant is flammable and inodorous. Furthermore, it can leads to explosion
under certain conditions. But the flammability of the refrigerant is very low. It can
be ignited only by fire.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm
to the ozonosphere. The influence upon the greenhouse effect is also lower. R32
has got very good thermodynamic features which lead to a really high energy
efficiency. The units therefore need a less filling.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacture. Should repair be necessary, contact your nea-
rest authorized Service Centre. Any repairs carried out by unqualified personnel
may be dangerous. The appliance shall be stored in a room without continuously
operating ignition sources. (for example: open flames, an operating gas appliance
or an operating electric heater.) Do not pierce or burn.
Appliance shall be installed, operated and stored in a room with a floor area larger
than 10m2.
Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s
instructions only. Be aware that refrigerants may not contain an odour. Read specialist’s
manual.
