HARVEST SEQUENCE5. HarvestThe water pump de-energizes stopping flow over theevaporator. The rising level of water in the sumptrough diverts water out of the overflow tube, purgingexcess minerals from the sump trough. The hot gasvalve also opens to divert hot refrigerant gas into theevaporator.The refrigerant gas warms the evaporator causing thecubes to slide, as a sheet, off the evaporator and intothe storage bin. The sliding sheet of cubes contactsthe ice damper, opening the bin switch.The momentary opening and re-closing of the binswitch terminates the Harvest Sequence and returnsthe ice machine to the Freeze Sequence (steps 3 - 4).AUTOMATIC SHUT-OFF6. Automatic Shut-offWhen the storage bin is full at the end of a harvestsequence, the sheet of cubes fails to clear the icedamper and will hold it down. After the ice damper isheld open for 7 seconds, the ice machine shuts off.The ice machine remains off for 3 minutes before itcan automatically restart.The ice machine remains off until enough ice has beenremoved from the storage bin to allow the ice to fallclear of the damper. As the ice damper swings back tothe operating position, the bin switch re-closes and theice machine restarts (steps 1 - 2), provided the3 minute delay period is complete.80 Part Number 80-01111-9 7/10
