Connect the thermistor wire to the indoor unit switch box. Make
sure power supply is switched off. Refer to the wiring diagram
delivered with the indoor unit.

The distance between the thermistor cable and power supply

(A3P) on the PCB.

2 Fix the cables to the cable tie mountings with cable ties to

ensure strain relief.

obstruct mounting of the indoor unit cover.
