(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 feet) long, proportionally increase the sectional area of power
cord to avoid overload.
(3)
Above selection requirements: Power cord size is based on BV single -core wire (2~4pc) at 40°C (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 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).
(5)
If the supply cord is damaged, it must be replaced by a qualified technician in order to avoid a hazard.
