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 proccedures.

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 product hopper(s).

3.Remove the hole plug(s) in the auger motor mounting panel.

4.Rotate the control at the base of the solenoid clockwise to decrease or counterclockwise to increase the amount of water.

5.Reinstall plug(s) and hopper(s).

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 produce a wide range of dispense rates 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.
