ADJUSTING BRIDGE THICKNESS
For optimum ice production and maximum cube separation, the ice connecting the individual cubes
should be a minimum of 1/8
I
(.32cm.) thick (See Figure 9). When adjusting the ice thickness, the adjust
Led is on the control board, it will be on for four seconds when it is at nominal voltage 2.4 to 2.5 VDC
2% (See Figure 8 for location of the J9 connector).
BRIDGE 1/8
I
(0.32 cm.)
FIGURE 9
Should a different thickness of the bridge be desired, it will be required to adjust the ice thickness “POT”,
located on the circuit board, as follows:
1. Thinner Bridge – turn the ice thickness “pot” adjustment screw C.W. one full turn. Allow two cycles
before determining if additional adjustments are required.
2. Thicker Bridge – turn the ice thickness “pot” adjusting screw C.C.W. one full turn. Allow two cycles
before determining if additional adjustments are required.
NOTE: Steady light indicates nominal setting, flashing light indicates the end of the adjustment
range.
NOTE: Never judge the thickness of the ice from the first batch of the ice produced – the first
cycle is a balance cycle. Always wait for the second cycle before making any adjustments.
TOTAL ICE CAPACITY
Ice capacity of any ice maker is affected by many operating conditions, such as water and air tempera-
ture 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% in-
crease in cycle time and capacity decrease of approximately 17%.
ICE PRODUCTION CHECK
If air cooled:
S
Take the air temperature at the intake of the condenser, 2
I
from the condenser fins.
S
Take the incoming water 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
condenser outlet temperature to 108
