Notes)

1. : indicates a terminal block

2.Broken line and chain line indicate wiring at local site.

3.For the inner wiring diagram of the outdoor unit and the indoor unit, refer to the wiring diagram of each model.

4.There is no polarity. It is no problem that the remote controller is connected to the indoor unit terminal block A and B reversely.

5.When using a wireless remote controller, connection of the remote controller to A and B terminal blocks are unnecessary. (Wire connection between indoor unit No.1 and No.2 is necessary.)
