clumps are added to the hopper. Sugar clumps may clog the hopper outlet and affect the accuracy of
dispense amounts.
Hopper Strainers
All AC6.E Sugar dispensers have a small stainless steel strainer at the base of the sugar
hopper. That strainer is necessary for proper operation of the dispenser and should not be removed,
except for cleaning.
Some models of AC6.E Sugar dispensers have a second, larger stainless steel strainer at the
top of the sugar hopper. That strainer is optional for general dispenser operation but it must be used
with ClumpBusters. See page 8.
NOTE: The Warranty will be null and void if the dispenser is serviced by unqualified personnel. Service
under Warranty must be approved and dispatched by A. C. Dispensing Equipment Inc. before the

Calibration Procedure – for dispense buttons:
NOTE:
•Dispensers with Serial Numbers up to and including 5005-11617 dispense on timers
located on the Circuit Board. Follow Step 5, Procedure A. See Picture, page 20.
•Dispensers with Serial Numbers 5005-11618 and above dispense on timers controlled by
a microprocessor on the Circuit Board. Follow Step 5, Procedure B. See Picture, page 20.
1. Install a new dispense tube on the dispenser.
2. Fill the product hopper.
Place a clean container under the dispense tube to catch sugar dispensed during calibration.
3. Run 2 cups of sugar through the dispenser by continuously dispensing the small size button to
break in the new dispense tube.
4. Using either a digital scale or a measuring vial, dispense from each size button and record the
measured amounts dispensed.
5. If these amounts are not correct: remove the back panel from dispenser and locate the circuit board
PROCEDURE A:
a locate the blue adjustment pots with slotted screw heads labelled small to x-large or x to large
b insert a small slot screw driver into the head and adjust clockwise to increase the amounts or
counter-clockwise to decrease the amounts
PROCEDURE B:
a Press the Program button. (All Binary LEDs will illuminate)
b Select the Size button required to be adjusted on the button panel. (solenoid will activate, use a
clean container to catch the sugar dispensed)
c The Scale Led will flash the number of times corresponding to the multiplier value used in Table 1
•The Binary LEDs will indicate the binary value used to determine the portion timing when
multiplied by the Scale value. E.g., 3 flashes, multiply by 10. See Table 1.
d To adjust the Binary values use the UP or DOWN buttons to increment or decrement this value.
e Press the size button to sample the new setting for correct portion amount.
Repeat step 5 to further adjust portion amount if necessary.
•When all Binary LEDs are illuminated the program will re-scale to the next higher scale
available, which will cause the binary value to be re-calculated accordingly.
•When adjusting to a lower portion timing, the program will always select the lowest scale value
possible that can represent the portion timing using the allowed binary value.
g To reset portion timing to factory setting, select portion to be reset on button panel, press both the
UP and DOWN buttons on the Circuit Board, then release.
