ADJUSTING BRIDGE THICKNESS
Adjusting Bridge Thickness
For optimum ice production and maximum cube
seperation, the ice connecting the individual cubes
should be 1/8" to 3/16" (.32cm to .475cm) thick at the
center of the ice waffle.
NOTE: Less than 1/8" (.32cm) may cause harvest
problems.
The ice thickness switch bank (a set of 8 DIP
switches) is factory set for a normal ice bridge thickness
of 1/8" (.32cm).
NOTE: Never judge the thickness from the first batch
of ice produced - the first cycle is a balance
cycle. Always wait for the second cycle be-
fore making any adjustments.
Should a desire be for a different thickness, adjust
as follows:
1. Thinner Bridge - Move one switch at a time to
the OFF position and check the bridge after the
harvest cycle.
Example - Switches are set 1 through 4 ON.
Place switch #4 to the OFF position - check
bridge after harvest. If additional adjustment is
required, return switch #3 to the OFF position,
etc.
2. Thicker Bridge - Move one switch at a time to
the ON position and check the bridge after the
harvest cycle.
Example - Switches are set 1 through 4 ON.
Move switch #5 to the ON position - check bridge
thickness after harvest. If additional adjustment
is required for a thicker bridge, move switch #6
to the ON position, etc. until desired bridge thick-
ness is reached.
3. If after adjusting the DIP switches additional ad-
justment is needed, please use the coarse ad-
justment. This potentiometer adjustment is to the
left of the DIP switches. With a DFE mechanical
relay circuit board for thicker ice, please turn this
counter clockwise. For thinner ice with a DFE
mechanical board, turn the potentiometer clock-
wise. For all other boards, turn the potentiom-
eter clockwise for thicker ice while turning
counter clockwise for thinner ice.
NOTE: Any bridge thickness adjustment during the
freeze mode will not take effect until next
cycle.
