HARVEST ASSIST AIR PUMP
FUNCTION
The air pump breaks the vacuum between the sheet of
ice and the evaporator which results in shorter harvest
cycles.
SPECIFICATIONS
230 Volt - matches the ice machine voltage.
CHECK PROCEDURE
1. The air pump is wired in parallel with the harvest
valve - Verify the ice machine is in the harvest
cycle and the harvest valve is energized.
2. If there is voltage at the air pump connector, use a
volt ohm meter to verify there is no continuity
through the motor windings then replace motor.
