1 Safety Precautions 

 

(1)  This product can’t be installed at corrosive, inflammable or explosive environment or the place with special 

requirements, such as kitchen. Otherwise, it will affect the normal operation or shorten the service life of the unit, 
or even cause fire hazard or serious injury. As for the above special places, please adopt special air conditioner 
with anti-corrosive or anti-explosion function. 

(2)  Follow this manual to complete the installation work. Please read this manual carefully before turning on or 

repairing the unit. 

(3)  Installation should be conducted by the dealer or qualified personnel. Please do not attempt to install the air 

conditioner by yourself. Improper installation may lead to water leakage, electric shock or fire hazard, etc. 

(4)  Before installation, please check whether the power supply is complied with that specified on the nameplate and 

check the safety of the power supply.   

(5)  The air conditioner must be grounded reliably for avoiding electric shock. Please do not connect the earthing wire 

to gas pipe, water pipe, lightning rod or telephone line. 

(6)  Be sure to use special accessories and parts for installation to prevent water leakage, electric shock and fire 

hazard, etc. 

(7)  If refrigerant leakage happens, please ventilate the room immediately.   
(8)  Diameter of power cord should be large enough. The damaged power cord and connection wire must be replaced 

with special cables. 

(9)  When the power cord is connected, please fix the electric box cover properly to avoid safety accidents. 
(10)  Never fail to comply with the nitrogen-charging welding process. Do charge nitrogen when welding the pipes.     
(11)  Never short circuit or cancel the pressure switch to prevent unit damage.   
(12)  As for the unit controlled by the wired controller, connect the wired controller well firstly and then energize the unit; 

otherwise, the unit can’t operate normally. 

(13)  When installation is finished, please check whether the drainage pipes, pipelines and electric wires are connected 

correctly to avoid water leakage, refrigerant leakage, electric shock or fire, etc. 

(14)  Do not insert fingers or objects into air outlet or air return grille. 
(15)  Open the door and window frequently to keep good ventilation for avoiding oxygen deficit when gas heater or oil 

heater is used in the room. 

(16)  Never plug in or unplug the power plug directly to turn on or turn off the air conditioner.   
(17)  Once the air conditioner is turned on, it can be turned off only after it has operated for 5min at least; otherwise, it 

will affect the oil return of compressor. 

(18)  Do not allow children to operate this air conditioner. 
(19)  Do not operate this air conditioner with wet hands. 
(20)  The air conditioner can be cleaned only when it has been turned off and the power has been cut off; otherwise, it 

may cause electric shock or injury. 

(21)  Never spray or flush water towards the air conditioner; otherwise, malfunction or electric shock may happen. 
(22)  Do not expose the air conditioner to the moist or corrosive environment. 
(23)  Put through the power 8 hours in advance before operation. Do not cut off the power when the air conditioner 

stops operation for only about one night (protect the compressor).   

(24)  Volatile liquid, such as diluent or gasoline, will damage the appearance of air conditioner. Only soft dry cloth and 

wet cloth dipped with neutral detergent can be used to clean the outer case of air conditioner. 

(25)  Under cooling mode, please don't set the room temperature too low; keep the temperature difference between 

indoor and outdoor within 5°C (41°F). 

(26)  If there are any abnormal circumstances (such as burning smell, etc.), please turn off the unit and cut off the main 

power supply immediately, and then contact Gree appointed service center. If those abnormal circumstances still 
exit, the unit may be damaged and it may lead to electric shock or fire hazard. 

(27)  Do not repair the unit by yourself. Wrong maintenance may cause electric shock or fire hazard. Please contact 

Gree appointed service center for help.
