ñ72ñIce Production CheckThe amount of ice a machine produces directly relates tothe operating water and air temperatures. This means acondensing unit with a 70∞F (21.2∞C) outdoor ambienttemperature and 50∞F (10.0∞C) water produces moreice than the same model condensing unit with a 90∞F(32.2∞C) outdoor ambient temperature 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 ProductionChart. Use the operating conditions determined instep 1 to find published 24-Hour IceProduction:_____• 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.)3. Perform an ice production check using the formulabelow.Weighing the ice is the only 100% accurate check.However, if the ice pattern is normal and the1/8 in. thickness is maintained, the ice slab weightslisted with the 24-Hour Ice Production Charts may beused.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
