(1)  Use copper wire only as unit’s power cord. Operating temperature should be within its rated value. 
(2)  If the power cord is more than 15m (49-1/4 ft.) long, please increase properly the sectional area of power cord 
to avoid overload, which may cause accident. 
(3)  Above selection requirements: Power cord size is based on BV single-core wire (2~4pc) at 40 
℃

ambient temperature when laying across plastic pipe. Air switch is D type and used at 40 ℃ (104 ℉). If actual 
installation condition varies, please lower the capacity appropriately according to the specifications of power 
cord and air switch provided by manufacturer. 
(4)  Install cut-off device near the unit. The minimum distance between each stage of cut-off device should be 
3mm(1/8 inch) (The same for both indoor unit and outdoor unit).
