NOTES!
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 long, please increase properly the sectional area of
power cord to avoid accident due to overload.
③ Above selection requirements: Power cord size is based on BV single-core wire (2~4pc) at
40°C ambient temperature when laying across plastic pipe. Air switch is D type and used at
40°C. If actual installation condition varies, please lower the capacity appropriately
according to the specifications of power cord and air switch provided by manufacturer.
(2) Install cut-off device near the unit. The minimum distance between each stage of cut-off
device should be 3mm (The same for both indoor unit and outdoor unit).
(3) If the supply cord is damaged, it must be replaced by the manufacturer or its service agent
or a similarly qualified person in order to avoid a hazard.
