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

For applied parts and numbering refer to the wiring diagram sticker supplied on the unit. Part numbering is realized by Arabic numbers in ascending order for each part and

 is represented in the overview below by symbol “*” in the part code.
