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 R290, which is specially cleaned.
The refrigerant is flammable and inodorous. Furthermore, it can leads to explosion
under certain conditions.
Compared to common refrigerants, R290 is a nonpolluting refrigerant with no harm
to the ozonosphere. The influence upon the greenhouse effect is also lower. R290
has got very good thermodynamic features which lead to a really high energy
efficiency. The units therefore need a less filling.
Please refer to the nameplate for the charging quantity of R290.
Appliance filled with flammable gas R290.
Before install and use the appliance, read the owner’s manual first.
Before install the appliance, read the installation manual first.
Before repair the appliance, read the service manual first.
