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 on the rear of the dispenser 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 beverage solenoid is 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 to adjust dispense valves 1, 2 & 3, and remove the small right side
access panel to adjust dispense valves 4 & 5.
3. Rotate the control at the base of the solenoid clockwise to decrease or counterclockwise to increase the amount
of water.
4. Replace appropriate access panels when finished.
HOPPER MOTOR SPEED PROGRAMING
The hopper dispense rate is preset at the factory. With 22 tooth gear and auger wire the preset dispense rate is
approximately 3 to 5 grams per second. With 30 tooth gear and auger wire the preset dispense rate is approximately
5 to 7 grams per second. The hopper dispense rate can be adjusted to a range of dispense rates from approximately
1.5 to 12 grams per second, as follows:
1. Place the rinse/run switch in the center (program) position.
2. Place the increase/decrease switch in the desired (increase or decrease) position.
3. 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.
