Part Number 80-1479-3 7/10 167
LOW PRESSURE CUTOUT (LPCO) CONTROL
(S3300 Only)
FUNCTION
Signals the control board to energize and de-energize
the ice machine when suction pressure rises above or
falls below setpoint.
The LPCO control is closed at pressures above
setpoint and opens at pressures below setpoint..
CHECK PROCEDURE
1. Connect manifold gauges at suction and
discharge access valves and verify refrigerant
pressure exceeds LPCO cut-in.
2. Isolate LPCO electrical leads, connect a
multimeter and read resistance.
Open = Replace Switch
Closed = Switch OK
