After turning off the sub and main power switches, unplug the power cord. Make sure to take15
minutes before restarting the operation. It is very dangerous if sleep mode functions mistakenly
during the operation.
Moreover, the PCB may be damaged in case electric charge still remains inside.
Also, there is a possibility of electric shock because of high power voltage applied to the high-pres-
sure part of the power supply PCB assy. Take care to avoid contact with it.
