Precautions for Electric wiring
Electric wiring work should be conducted only by authorized personnel.
Do not connect more than three wires to the terminal block. Always use round
type crimped terminal lugs with insulated grip on the ends of the wires.
Use copper conductor only,the parameter of connecting cable is H05RN-F 4G
0.75mm

,but for AU182AEEAA,the parameter of connecting cable should be
H05RN-F 3G 2.0mm

The wiring method should be in line with the local wiring standard.
The breaker of the air conditioner should be all-pole switch; and the distance
between its two contacts should be no less 3 mm.
If the supply cord is damaged, it must be replaced by the manufacturer or its
service agent or a similar qualified person.
If the fuse on PC board is broken please change it with the type of T3.15A/250VAC.
Select wire sizes and circuit protection from table below. (This table shows 20 m
length wires with less than 2% voltage drop.)
WARNING
(2) Wiring connection
Make wiring to supply power to the outdoor unit, so that the power for the indoor
unit is supplied by
