Ice capacity test
Ice machine production capacity can only be determined by weighing ice produced in a specific time period.
1. Remove top panel and hopper lid of unit.
2. Weigh and record weight of container used to catch ice.
3. Run ice machine for at least 15 minutes.
4. Catch ice for 15 or 20 minutes.
5. Weigh harvested ice and record total weight.
6. Subtract weight of container from total weight.
7. Convert fractions of pounds to decimal equivalents (Ex. 6 lbs 8 oz = 6.5 lbs).
8. Calculate production using following formula:
1440 min. x wt. of ice produced
Total test time in minutes
9. Calculated amount per 24 hours should be checked against rated capacity for same ambient and
water temperatures in Ice Production Table (see page 23).
