1) Replace the PCB after elapsing 3 minutes from power OFF.
(Be sure to measure voltage (DC) on both capacitor terminals located in control
back, and check that the voltage is discharged sufficiently.)
2) Disconnect the connectors from the control PCB.
3) Disconnect the white wiring passing through CT1 on the PCB before replacing the PCB.
4) Match the setting switches (SW3-5, JSW) with the former PCB.
5) Tighten up a screw after passing white wiring through CT1 of the changed.
6) Connect the connectors with the control PCB referring to the parts arrangement of Fig.1.
(Confirm the connectors are not half inserted.)
