Cautions when Servicing
!
WARNING: When the main supply is turned off, the voltage [340 V] in the main capacitor will drop to 20 V in approx. 2 minutes (input voltage: 230 V). When servicing, make sure that
LED1 (green) on the outdoor circuit board goes out, and then wait for at least 1 minute.
Components other than the outdoor board may be faulty: Check and take corrective action.
Do not replace the outdoor board without checking.
