●Discharging method
(1) remove the inverter cover(Outdoor Unit)
(2)As shown below,connect the discharge resistance(approx.100Ω20W)or plug of the sold ering iron to voltage between + - terminals of
the electrolytic capacitor on PC Board for 30s, and then peformedischarging.
NOTE:
A large-capacity electrolytic capacitor is used in the outdoor unit controller(inverter).Therefore,if the power supply is turned
off,charge(charging voltage DC280V to 380V)remains and disc harging takes a lot of time.. After turning off the power source,if touching
the charging section before discharging, an electrical shock may be caused. Discharge the electrol ytic capacitor completely by using
soldering iron,etc.
