TOTAL ICE CAPACITY
Ice capacity of any ice maker is affected by many operating conditions, such as water and air temperature and
location factors. Please review the capacity tables in this manual for average 24-hour capacity under various
conditions.
NOTE: All printed capacity ratings are 10% except 50 HZ units. These products have 12% increase
in cycle time and capacity decrease of approximately 17%.
ICE PRODUCTION CHECK
If air cooled, take air temperature at the intake of the condenser, 2I from the condenser fins, and Incoming wa-
ter temperature at the outlet of the “fill” valve.*
Cycle time (CT) = freeze time plus harvest time, in minutes and seconds. 1440 divided by CT = number of
cycles per 24 hours.
Measure weight of ice from one cycle in pounds and fractions of a pound.
EXAMPLE: Weight/cycle x cycles/day = total production/24 hrs. Compare to the production tables.
* If water cooled, be certain water regulator valve is set to maintain 260 - 271 PSI head pressure, or set con-
denser outlet temperature to 108_F – 111_F
LED INDICATORS
The LEDs are board circuit indicators. If the LED in the functional board circuit is complete, check component.
Example: Contactor does not energize and LED is “ON”, board circuit is OK. Check contactor, coil, leads, &
connections.
Yellow:
S Evaporator switch(s) (proximity)
Green:
S Water dump valve
S Compressor contactor
S Water Pump
S Hot Gas Valve
S Condenser Fan (cycles on & off with fan)
S Fill Valve
Red:
S Error (located on the electrical box front).
S Delay (located on the electrical box front).
S Ice thickness Adjustment.
Refer to flash codes for control and system diagnostics. Add the flash codes before status indicators.
FLASHING CODE FOR SELF DIAGNOSTICS (300’s, 500’s, 600’s, 800’s,
1000’s, and 1200’s)
