Pay attention to the phase sequence of the power supply. If the phase sequence is reversed, the compressor will not start.
Meanwhile, the fault indicator of the outdoor electric control board will light up. For details, see Outdoor unit wring diagram on the
cover plate of the electric control box .
After shifting the phase sequence, power on the unit until the fault indicator goes out and the compressor starts up normally.
