Safety Timers - Manitowoc S300 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.
Freeze lock is bypassed after moving the toggle
switch from OFF to ICE position for the first cycle
only.
• 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 for
single evaporators and 7 minutes for Quad
evaporator model. The control board automatically
initiates a freeze sequence (steps 3 & 4) when
these times are exceeded.
