52 Part Number 80-1479-3 10/10Ice Production CheckThe amount of ice a machine produces directly relatesto the operating water and air temperatures. Thismeans an ice machine with a 20°C outdoor ambienttemperature and 10.0°C water produces more ice thanthe same model ice machine with a 32°C outdoorambient and 21°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 ProductionChart.3. Use the operating conditions determined in Step 1to find published 24 hr. 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 grams.4. Perform an ice production check using the formulabelow.Weighing the ice is the only 100% accurate check.Compare the results of Step 3 with Step 2. Iceproduction is normal when these numbers matchclosely. If they match closely, determine if: Another ice machine is required.Relocating the existing equipment to lower the loadconditions is required.1. _________Freeze Time+ _________Harvest Time= _________Total CycleTime2. 1440_________Minutes in24 Hrs._________Total CycleTime_________Cycles per Day3. _________Weight of OneHarvest× _________Cycles per Day= _________Actual 24-HourProduction
