Record your findings on the refrigeration diagnostic chart. covert to 9.25 lbs 4 oz divided by 16 oz = 0.25 lbs.Ĭompare your findings in the ice production check to published specifications in operating conditions. For example: 1 minute, 15 seconds convert to 1.25 minutes 15 seconds divided by 60 seconds = 0.25 minutes. Note: To use the 24-hour ice production formulas, time must be in minutes and weight of ice in pounds (lbs). Weight of one harvest times cycles/day = lbs/24 hours. 1,440 divided by total cycle time = cycles/day.ģ. Freeze time plus harvest time = total cycle time.Ģ. The published 24-hour ice production at the above conditions (in lbs/24 hours).ġ. Water inlet temperature (entering sump trough).ģ. Make sure the water curtain is in place to ensure no water is being lost while checking ice production.Ģ. Use the following list to check ice production. An ice machine produces more ice in a 70 degree F room with 50 degree water than in a 90 degree room with 70 degree water. Step Two: Ice Production The amount of ice a machine produces is in direct relationship to water and air temperatures. Note: If you make any of these corrections, be careful not to interfere with the ice production inspection.

Remote condenser line set isn’t properly installed.

Water filtration is restricted (if used).

Run drains separate and vent according to the installation manual.

Drains not run separate and/or vented.

Install electrical in accordance with the installation manual. Ice machine not on separate fused electrical circuit.Ice machine not level side to side, back to front.Must have a minimum of 5 inches clearance around all sides and top of machine. Air space clearances at back and sides of ice machine.Reinstall in accordance with installation manual. Air temperature/airflow restrictions, etc.

Here are some possible problems and corrective measures: Were items such as boxes obstructing airflow moved from around the ice machine before you arrived?.Has anyone been working on the ice machine?.Can you describe exactly what the ice machine seems to be doing?.When do you notice low production (one day a week, every day, weekends, etc.)?.When is the ice machine malfunctioning (night, day, all the time, during the freeze cycle, harvest cycle, etc.)?.Here are a few questions to consider asking the user: The user’s information could help point you in the right direction initially, and may be a determining factor in your final diagnosis. Step One: Visual Inspection Talk to the ice machine user to identify the perceived problem(s). Editorial Calendar & Editor Assignments.
