Precautions
Please read this operating manual carefully before operating the unit.
Appliance lled with ammable gas R32.
Before use the appliance, read the owner's manual rst.
Befoer install the appliance,read the installation manual rst.
Befoer repair the appliance ,read the service manual rst.
The gures in this manual may be different with the material objects, please refer to the
material objects for reference.
To realize the function of the air conditioner unit, a special refrigerant circulates in the system.
The used refrigerant is the uoride R32, which is specially cleaned. The refrigerant is
ammable and inodorous. Furthermore, it can leads to explosion under certain condition.
But the ammability of the refrigerant is very low. It can be ignited only by re.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the
ozonosphere. The inuence 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 lling.
The Refrigerant
WARNING:
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 nearest
authorized Service Center.
Any repairs carried out by unqualied personnel may be dangerous.
The appliance shall be stored in a room without continuously operating ignition sources.
(For example: open ames, an operating gas appliance or an operating electric heater.)
