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 (21.2°C) ambient temperature and 50°F (10.0°C) water produces more ice 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
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.
1. _______ |

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.
