WATER PAN CLOSES/FREEZE:
When the water pan closes and the hall
IC turns on the water valve opens to
supply ice making water for a specific
time. The supply time varies between
startup, reset, and end of bin control
cycle between partial flush and full
drain.
NOTE Full drain flush: After a freeze
cycle ends the unit drains all remaining
water out of the tank and refills for the
next freeze cycle.
Partial drain flush: (default setting)
After a freeze cycle ends, the unit leaves
remaining water in tank and adds water
for the next cycle.
After water has been supplied the pump
motor starts, after 30 seconds the
thermistor senses the temperature that
will be added with a predetermined
offset value and used as the water
temperature for the freeze cycle, pan
opening, defrost, and pan closing cycle.
The freeze cycle is considered to be
100% complete when the predetermined
target and the integrated values are
reached. To reduce ice forming on the
water pan when the freeze completion
rate reaches 100% with an ambient
temperature below 86º F (30ºC), the hot
gas valve opens and closes two times to
raise the water pan temperature and the
actuator motor starts to open the water
pan. The freeze cycle is not considered
complete and the pump motor and fan
motor continue. The unit will continue
to cycle between freeze and harvest until
the bin control opens, signaling a full
bin or until power is interrupted
