CAUTION
Note that operation will restart automatically if the main power supply is turned off and then back on again.
HIGH VOLTAGE – be sure to discharge the capacitor completely before repair work.
Risk of failure or water leakage!
Do not wash the inside of the air conditioner by yourself.
Unified Wiring Diagram Legend
