Thaw Cycle - Manitowoc QuietQube Series Technician's Handbook

THAW CYCLE

When the damper/curtain does not open during the 7
minute harvest cycle the following ice thaw cycle occurs:
• The compressor, harvest solenoid valve and dump
valve de-energize.
The water pump remains energized and the water inlet
valve energizes until water touches the high water
level probe.
• Water is circulated, dumped and refilled to the high
water level probe for 3 minutes.
Model 1200 or smaller:
Circulate 165 seconds, dump 45 seconds
Model 1400 and larger:
Circulate 240 seconds, dump 120 seconds
• At the end of the thaw cycle the ice machine will start
another freeze cycle (approximately 1 - 1.75 hour).
Curtain Operation In Water Assist Harvest
• Open & close damper = Continue Thaw Cycle

Use the keypad and turn the ice machine off and then on
to terminate the cycle. Disconnecting and reconnecting
power to end the cycle will result in the ice machine
restarting in a harvest cycle.
