Replacing/Refitting the Controller Board Assembly
To replace/refit the controller board assembly, proceed as follows:
1. Visually inspect the controller board assembly to ensure that there is sufficient thermal
compound on the mounting bracket directly below the steam generator triac.
2. Install the controller board assembly using the three screws with washers retained from
removal (or fit new if replacing with a new board).
3. Connect the high voltage leads from the power switch, steam generator, pump, solenoid
valve and compressor to controller board J1 terminal (12). Each lead is numbered with a
corresponding J1 designation. See Table B.
