Cycle time (CT) = freeze time plus harvest time, in minutes and seconds. 1440 divided by CT = number of
cycles per 24 hours.
Measure weight of ice from one cycle in pounds and fractions of a pound.
Example: Weight/cycle x cycles/day = total production/24 hrs. Compare to the production tables
* If water cooled, be certain water regulator valve is set to maintain 225/235 PSI head pressure.
