and the terminal number are the same as those of the
indoor unit.
1. Remove the electrical box cover from the outdoor unit
by loosening the screw.
2. Connect wires from the Indoor Unit to the terminals on
the Outdoor Unit as identified by their colours.
3. Secure the cable onto the control board with the
cord clamp.
4. Be sure to install the power supply for all models
according to the diagram below. Be sure to firmly
connect the Earthing wire.
