WATER PLATE ALIGNMENT
If the water plate is not aligned with the evaporator,
the cubes may appear cloudy or misshapen.
Dimension "A" is not adjustable. If this dimension
is out of tolerance, the evaporator or water plate
mounting components may be damaged.
Adjustments to dimension "B" can be made by sliding
the front and rear hinges along the left edge of the
water plate. Lightly tap the hinges as required to
align the water plate with the evaporator. Alignment is
correct when the space between the evaporator and
the water plate is equal in front and in back.
"A" = 1.5" ± 3/32" (38 mm ± 2.5 mm)"B" = 5/16" ±
1/16"(8 mm ± 1.5 mm)
WEB THICKNESS ADJUSTMENT
The web thickness between cubes (the gap between
the bottom of the evaporator and the water plate
surface) can be adjusted by inserting or removing
shims between the support channels and the
evaporator support posts or the cam shaft bearing
brackets. Loosen the actuator motor mounting
screws before inserting or removing shims between
the channels and cam shaft bearing brackets. The
web thickness specification for both C and HK models
is 1/16" (2mm)
WATER PLATE UP/DOWN POSITION AND
ADJUSTMENT
When the water plate is up (closed),
the spring end of the cam arm must
be in the 12 o'clock position, with
the spring on the left side of the
cam arm hub. The arms up switch
lever (front) will be down and the
arms down switch lever (back) will
be up. When the water plate opens,
the cam arm turns counterclockwise
until the arms down switch operator
allows the arms down switch lever to
drop. When the water plate is fully
down (open), the cam arm should
be in the seven o'clock position; the
spring should be aligned with the
cam arm. When closing again, the
cam arm will turn clockwise, until the
arms up switch operator allows the
arms up switch lever to drop.
The positions of the cam arms, when the water plate
is open and closed, may be adjusted by loosening
the set screws and rotating the switch operators as
required. Baseline positions of the switch operators
for the front and back are 11 and 4 o'clock when
the water plate is up. When the water plate is down,
positions for the front and back switch operators are 6
o'clock and 11 o'clock
Note: The front operator is for adjusting the arms up
switch and the back operator is for adjusting the arms
down switch.
Up Position
• If the cam arm in the up position is too far
clockwise from 12 o'clock rotate the front switch
operator clockwise to stop the arm's rotation earlier
• If the cam arm in the up position is too far
counterclockwise from 12 o'clock rotate the front
switch operator counterclockwise to stop the arm's
rotation later Down Position
• If the cam arm in the down position is too
far clockwise from 7 o'clock rotate the back switch
operator clockwise to stop the arm's rotation later
• If the cam arm in the down position is too
far counterclockwise from 7 o'clock rotate the back
operator counterclockwise to stop the arm's rotation
earlier
