ConnectthecabletotheIndoorunit

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 ground wire should be longer than the common wires. The circuit diagram is subject to change without notice.

When installing, refer to the electrical diagram behind the front panel of Indoor Unit.

The wiring for the outdoor unit can be found on the inside of the Outdoor Unit control cover.

RECOMMENDATION:

The circuit diagram is subject to change without notice.

Be sure to connect wires according to the wiring diagram.

Connect the wires firmly, so that they can not be pulled out easily.
