Safety Timers; Water Assist Harvest Feature - Manitowoc Indigo Series Technician's Handbook

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 89
• 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 12.5 minutes (16.5 minutes
for dual evaporator models).

WATER ASSIST HARVEST FEATURE

Twin 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.
