(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 15 m (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° (104°F) ambient
temperature when laying across plastic pipe. Air switch is D type and used at 40°C (104°F). 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 3 mm
(1/8 inch) (The same for both indoor unit and outdoor unit).
