COLD BEVERAGE SET-UP (OPTIONAL)
Cold beverages may be dispensed from the left dispense position. Simply place the HOT/COLD switch near the
left whipper chamber in the “COLD” (upper) position.
CLEANING
Refer to the decal inside the hopper access door for cleaning recommendations and procedures.
The use of a damp cloth rinsed in any mild, non-abrasive, liquid detergent is recommended for cleaning all
surfaces on Bunn-O-Matic equipment.
ADJUSTMENTS
The hot or cold beverage solenoids are preset to dispense approximately
9
/
10
ounce per second. This amount can
be adjusted:
1. Disconnect the dispenser from the power source.
2. Remove the small left side access panel.
3. Rotate the control at the base of the desired solenoid(s) clockwise to decrease or counterclockwise to increase
the amount of water.
4. For cold beverage adjustment remove the 1-1/2” plug on the lower left side of the dispenser and rotate the
needle valve clockwise to decrease or counterclockwise to increase the amount of cold water.
HOPPER DISPENSE RATE OF PRODUCT
NOTE: The hopper dispense rates are preset at the factory. With 22 tooth gear and auger wire the preset dispense
rate is approximately 3 to 5 grams per second. With 32 tooth gear and auger wire the preset dispense is approxi-
mately 5 to 7 grams per second. The hopper dispense rates can be individually programmed to produce a wide
range of dispense rates as follows:
1. Place the rinse/run switch in the center (program) position.
2. Hold the increase/decrease switch in the desired (increase or decrease) position.
3. While holding the increase/decrease switch, press and release the dispense switch for the chamber you wish
to adjust. Each time the dispense switch is pressed, the rinse L.E.D. will flash, and the motor speed for that
hopper will be increased/decreased by approximately 2 1/2%.
4. Return the rinse/run switch to the run position after hopper motor speed adjustments are complete.
5. Once any of the three hopper motors has been programmed to the desired speed, either or both of the other
hopper motors can be set to the same speed as follows:
a. Place the rinse/run switch in the center (program) position.
b. Press and hold the dispense switch that has been programmed for the correct speed.
NOTE: Care must be taken not to exceed 5 seconds, or a hopper throw test will occur.
c. Momentarily press the dispense switch for the hopper motor to be programmed. The rinse L.E.D. will light
for approximately 1 second, indicating that the speeds have been set equal.
d. Release both dispense switches.
e. Repeat step 5. b. through 5. d. for remaining hopper motor if desired.
f. Return the rinse/run switch to the run position after hopper motor speed adjustments are complete.
HOPPER THROW TEST
The hopper throw rate, grams per second (g/s) or ounces per second (oz./s), can be checked by automatically
running the hopper motor for 10 seconds.
1. Remove the steam collector and mixing chamber from under the hopper to be checked.
2. Position a small cup under the hopper outlet.
3. Place the rinse/run switch in the center (program) position.
