Discharge Procedure
RAC-18/25/35WEF
1. Turn off the power.
2. After power is turned off, wait for 10 minutes or more. Then, remove electrical parts cover
and apply soldering iron of 30 to 75 W for 15 seconds or more to IPM (24) and IPM (20)
terminals on the main P.W.B. as shown in the figure below, in order to discharge voltage
in smoothing capacitor.
Voltage of about 350 V is charged between the terminal of smoothing capacitors.
During continuity check for each circuit part of the outdoor unit, be sure to discharge the smoothing
capacitors.
