ICE PRODUCTION CHECKThe amount of ice a machine produces directly relates to theoperating water and air temperatures. This means an icemachine with a 70°F (21.2°C) ambient temperature and 50°F(10.0°C) water produces more ice than the same ice machinewith 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 tofind 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 the formulabelow.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 ProductionWeighing the ice is the only 100% accurate check. However,if the ice pattern is normal and the 1/8" (.44 cm) thickness ismaintained, the ice slab weights listed with the 24-Hour IceProduction Charts may be used.4. Compare the results of step 3 with step 2. Ice productionis normal when these numbers match closely. If theymatch closely, determine if:Another larger ice machine is required.Relocating the existing equipment to lower the loadconditions is required.Contact the local Manitowoc distributor for information onavailable options and accessories.Part Number 80-01111-9 7/10 103
