4. Remove the electrical wiring box (if necessary).

1) Disconnect the inter-unit wire.
2) Disconnect the fan motor connector (S200) and swing motor connector (S6).
3) Disconnect the thermistor and ground wire from the heat exchanger (2 screws).

(Some models may not have ground wire.)

4) Remove the mounting screw of the electrical wiring box (1 screw).

If there is workspace on the right-hand side of the indoor unit, the installation work can be conducted without removing the
electrical wiring box. Connect the HA PCB without removing the electrical wiring box, if possible.

5. Install the HA PCB to the electrical wiring box.

1) Attach the harness (with ferrite core), by connecting it to the S601 and S602 connectors on the HA PCB. (See

Fig. 2

)

2) Insert the connector of the harness (with ferrite core) into the S403 connector
on the electrical wiring box. (See

Fig. 2

)

3) Install the HA PCB to the electrical wiring box. (See

Fig. 2

)

4) Insert the connection cord into the S21 connector (white) on the HA PCB. (See

Fig. 3

)
