Select the same capacity with the PCB removed from the unit.
iii) Replace the PCB
① Unscrew terminal (Arrow A) of the “E1” wiring (yellow/green) that is connected to PCB.
② Replace the PCB only after all the wirings connected to the connector are removed.
③ Fix the board such that it will not pinch any of the wires.
④ Switch setting must be same setting as that of the removed PCB.
⑤ Reconnect the wirings to the PCB. Wiring connector color should match with the color of connector of the PCB.
⑥ Screw back the terminal(Arrow A) of the “E1” wiring, that was removed in ①.
iv) Control PCB
Parts mounting are different by the kind of PCB.
