Connect the cable to the indoor unit by connecting the wires to the terminals on the control board
individually according to the outdoor unit connection. (Ensure that the color of the wires of the outdoor
unit and the terminal No. are the same as those of the indoor unit.)
The earth wire should be longer than the common wires.
The above circuit diagram is subject to change without notice.
