Diameter of power cord 
should be large enough. The 
damaged power cord and 
connection wire must be 
replaced with special cables. 

 

When the power cord is 
connected, please fix the 
electric box cover properly 
to avoid safety accidents. 

 

Never fail to comply with the 
nitrogen-charging welding 
process. Do charge nitrogen 
when welding the pipes.     

 

Never short circuit or 
cancel the pressure switch 
to prevent unit damage. 

 

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. 

 

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. 

 

Do not insert fingers or 
objects into air outlet or air 
return grille. 

 

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. 

 

Never plug in or unplug the 
power plug directly to turn on 
or turn off the air conditioner. 

 

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. 

 

Do not allow children to 
operate this air conditioner. 

 

Do not operate this air 
conditioner with wet hands. 

 

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. 

 

Never spray or flush water 
towards the air conditioner; 
otherwise, malfunction or 
electric shock may 
happen.
