ICE PRODUCTION CHECK
The amount of ice a machine produces directly relates to
the operating water and air temperatures. This means an
ice machine with a 70°F (21.2°C) ambient temperature
and 50°F (10.0°C) water produces more ice than the same
ice machine with 90°F (32.2°C) ambient and 70°F (21.2°C)
water.
1. Determine the ice machine operating conditions:
Air temp entering condenser: ____°
Air temp around ice machine: ____°
Water temp entering sump trough: ____°
2. Refer to the appropriate 24-Hour Ice Production
Chart. Use the operating conditions determined
in step 1 to find published 24-Hour Ice
Production:_____
• Times are in minutes.
Example: 1 min. 15 sec. converts to 1.25 min.
(15 seconds ÷ 60 seconds = .25 minutes)
• Weights are in pounds.
Example: 2 lb. 6 oz. converts to 2.375 lb.
(6 oz. ÷ 16 oz. = .375 lb.)
