Ice Production CheckThe amount of ice a machine produces directly relatesto the operating water and air temperatures. Thismeans an ice machine with a 70°F (21.2°C) ambienttemperature and 50°F (10.0°C) water produces moreice 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 ProductionChart. Use the operating conditions determined inStep 1 to 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 pounds.Example: 2 lb., 6 oz. converts to 2.375 lb.(6 oz. 16 oz. = .375 lb.)3. Perform an ice production check using theformula below.1. _______ + _______ = _______Freeze Time Harvest Time Total Cycle Time2. 1440 _______ = _______Mins in 24 hrs Total Cycle Time Cycles Per Day3. _______ x _______ = _______Weight of One Cycles Per Day Actual 24 HrHarvest Production4. Compare the results of Step 3 with Step 2. Iceproduction is normal when these numbers matchclosely. If they match closely, determine if:Another larger ice machine is required.Relocating the existing equipment to lower theload conditions is required.Part Number 80-01111-9 7/10 157
