ADJUSTING BRIDGE THICKNESS
For optimum ice production and maximum cube separation, the ice
connecting the individual cubes should be a minimum of 1/8I (.32cm)
thick at the center area of the ice waffle.
BRIDGE 1/8I (0.32 cm)
It is normal for the ice slab to be slightly thicker at the bottom and taper
off in a slight wedge pattern at the top. The top row of cubes must have
a complete pattern of ice on all four sides and the back wall. Remem-
ber, when you operate the product with the panels off during testing the
additional heat at the top of the evaporator will cause thinner ice at the
top than when the panels are in place.
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 fol-
lows:
1. Thinner Bridge – turn the ice thickness “pot” adjustment screw
CW one full turn. Allow two cycles before determining if
additional adjustments are required.
2. Thicker Bridge – turn the ice thickness “pot” adjusting screw CCW
one full turn. Allow two cycles before determining if additional ad-
justments are required.
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 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 “float” 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 300/310 PSI head pressure.
