Symptom: Low ice capacity.
Suspicions of low ice capacity should be confirmed by accurate calculations of actual ice product.
Much weight can be lost by melting and off fall through augers and other ice handling equipment.
1.
Time the total freeze and thaw cycle for the cycle which is to be caught and weighed.
2.
Catch all the ice at the ice discharge opening of the machine.
3.
Weight the total amount of ice caught.
Lbs. ice per cycle
Cycle time minutes
X
1440 =
_____ lbs. production per 24 hours
More than one cycle should be caught and weighed to get an accurate average.
Possible Cause
Possible Remedy
Inadequate water for ice making
Water pressure of 40 psig minimum is required
to assure proper water supply. Check water
pressure. Check for a restriction in the incoming
line or at the make-up water float valve.
Water distributors may be stopped up
Check distributors and clean orifices as needed.
Freeze timer, Freezer pressure switch or thaw
timer out of adjustment
Check hole size in Tube-Ice (See Table 7-2).
Crushed ice should be 3/16”-1/4” thick. Check
and adjust thawing time. Thawing should be 30
seconds longer than it takes for all the ice to
clear the freezer.
Excessive ice chips in the water tank, causing
short cycling
Check incoming water temperature (45
F
minimum). Check flushing valve to make sure
ice chips are being melted and flowing out the
tank overflow during the harvest cycle.
Compressor running unloaded or not pumping
full volume
Check compressor motor amp draw. Check for
belt slippage and tighten as needed. Check for
leaking compressor suction or discharge valves.
Refer to your compressor manual. See other
related symptoms.
Restriction in the refrigerant liquid line or float
switch not operating properly
Check for a partially closed valve or an
obstruction at the strainer, solenoid valve, or
hand expansion valve. The liquid line will
normally have frost on the downstream side of a
restriction, especially as the suction pressure
decreases.
Low refrigerant charge, causing re-freeze
Check the receiver gage glass mark for the
proper level. Check for and repair leaks. Add
refrigerant.
Warm make-up water for ice making
Capacity of the machine is proportional to ice
making water temperature. Warmer water will
reduce the ice making capacity. Check float
adjustment and water tank drain valve.
