FIELD CONVERSION NOTES

6 PAN MACHINES USE TWO GENERATOR HEATING ELEMENTS. ONE ELEMENT BETWEEN THE LIMITING CONTACTOR AND REGULATING CONTACTOR 1, IS NOT PRESENT

FOR 6 PAN MACHINES, TO CONVERT TO 240V, DISCONNECT THE BLACK ELEMENT LEAD FROM REGULATING CONTACTOR 2 AND ITS CORRESPONDING LEAD FROM THE LIMITING CONTACTOR. MOVE THE MAIN TRANSFORMER PRIMARY INPUT FROM THE H2 (208V) POSITION TO THE H3 (230V) POSITION

FOR 10 PAN MACHINES, TO CONVERT TO 240V, DISCONNECT THE BLACK ELEMENT LEAD FROM REGULATING CONTACTOR 2 AND THE WHITE ELEMENT LEAD FROM REGULATING CONTACTOR 1 AND THEIR CORRESPONDING LEADS FROM THE LIMITING CONTACTOR. MOVE THE MAIN TRANSFORMER PRIMARY INPUT WIRE #4 FROM THE H2 (208V) POSITION TO THE H3 (230V) POSITION
