Part Number Preliminary 6/11 131
SAFETY TIMERS
The control board has the following non-adjustable
safety timers:
• The ice machine is locked into the freeze cycle for
6 minutes before a harvest cycle can be
initiated.This can be overridden by initiating a
manual harvest. Refer to “Manual Harvest” on
page 98
• The maximum freeze time is 60 minutes at which
time the control board automatically initiates a
harvest sequence (steps 5 & 6).
• The maximum harvest time is 3.5 minutes at which
time the control board automatically ends the
harvest cycle. When the bin switch is closed a
freeze sequence initiates (steps 3 & 4). When the
bin switch is open an automatic shutoff sequence
initiates.
• The maximum water fill is 6 minutes.
WATER ASSIST HARVEST FEATURE
Twin & Quad Evaporators Only:
Typical duration of a Harvest sequence is less than 2.5
minutes. When the Harvest sequence time reaches 4
minutes, the following occurs:
4 minutes into a Harvest sequence: The water fill valve
will energize to fill the trough with water.
5 minutes into a Harvest sequence: The water pump
will energize and flow water over the evaporators.
The water fill valve and water pump remain on until all
bin switches have been activated, or until the 7-minute
Harvest sequence time limit is reached.
