N OT IC E
If it needs to install, move or maintain the air conditioner, please contact dealer
or local service center to conduct it at first. Air conditioner 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,

compliance with local laws and regulations.

The Refrigerant
WARNING
Appliance filled with flammable gas R290.
Before install the appliance, read the installation manual first.
Before repair the appliance, read the service manual first.
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 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.
1
Before install and use the appliance, read the owner’s manual first.
Appliance filled with flammable gas R290.
Appliance shall be installed, operated and stored in a room with a floor area:
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.
)
The appliance shall be stored in a well-ventilated area where the room size corresponds
to the room area as specified for operation.
The appliance shall be stored so as to prevent mechanical damage from occurring.
Ducts connected to an appliance shall not contain an ignition source.
Keep any required ventilation openings clear of obstruction.
Do not pierce or burn.
Be aware that refrigerants may not contain an odour.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
Servicing shall be performed only as recommended by the manufacturer.
Should repair be necessary, contact your nearest authorized Service Centre.
Any repairs carried out by unqualified personnel may be dangerous.
Compliance with national gas regulations shall be observed.
