Normal operation – Stage 1 - 220 V 60 Hz
The 220 V 60 Hz is identical to the 230 V 50 Hz EXCEPT that the compressor output and neutral are reversed, as
shown in the diagram below . The remaining Stages show only the 230 V 50 Hz applications .

Normal operation – Stage 2
When continuity is seen between B and C, the water valve de-energizes, the AUGER output (P4) comes on along
with the
MAKING ICE LED . The auger gearmotor’s start windings are energized through a current style start relay
that is pulled in by the initial high current draw of the gearmotor .
