For the wiring process of solenoid valve output PCB and external electronic expansion valve
kit, first remove the grille and then remove the electrical component cover and fixed plate of
terminal board.
OP1 (CN309, 3P Yellow): Solenoid valve output PCB’s power supply wiring connector
PMV (CN082, 5P White): External electronic expansion valve kit wiring connector
3WAY (CN081, 5P Black): Solenoid valve output PCB’s output wiring connector
Indoor unit control PCB
1. Make wirings as shown below. For external electronic expansion valve kit, see Figs. 7, 9.
2. Connect the solenoid valve output PCB to the indoor unit control PCB’s OP1, 3WAY and
tighten the ground screws.
Then, connect the external electronic expansion valve kit to the indoor unit control PCB’s
PMV.
3. Clamp the solenoid valve output PCB’s power supply wire routed from the solenoid valve
output PCB as shown in Fig. 8.
Align the clamper head with the rim of the chassis to avoid loosening the wire.
4. Return to the original position.
