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°C) ambient temperature and 50°F
(10°C) water produces more ice than the same ice machine
with 90°F (32°C) ambient and 70°F (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 Production Chart.
Use the operating conditions determined in Step 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 the formula
below.
Weighing the ice is the only 100% accurate check.
4. Compare the results of step 3 with step 2. Ice production
is normal when these numbers match closely. If they
match closely, determine if:
Another larger ice machine is required.
Relocating the existing equipment to lower the load
conditions is required.
Contact the local Manitowoc distributor for information on
available options and accessories.
