NOTICE
If it needs to install, move or maintain the appliance, please contact dealer or
local service center to conduct it at first. The appliance must be installed,
moved or maintained by appointed unit. Otherwise, it may cause serious
damage or personal injury or death.
When refrigerant leaks or requires discharge during installation, maintenance,
or disassembly, it should be handled by certified professionals or otherwise in
compliance with local laws and regulations.

1
The Refrigerant
To realize the function of the 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 lead 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.
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.
