ADJUSTING BRIDGE THICKNESS
For optimum ice production and maximum cube separation, the ice connecting the individual
cubes should be a minimum of 1/8” (.32 cm) thick at the center area of the ice waffle.
BRIDGE 1/8” (0.32 CM)
It is normal for the Ice Bridge 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.
REMEMBER: 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 follows:
