3.To decrease the pump speed, press and hold the left-hand “Hidden Switch” (half-filled circle) and then mo- mentarily press the “Product Dispense Switch (“+/STOP Switch” for portion control dispensers). Each time the “Product Dispense” (“+/STOP”) Switch is pressed, the motor speed is decreased by one step (5 RPM.) Note that each step is confirmed by a single flash of the appropriate “REFILL” indicator and a single tone from the beeper.

4.Repeat as necessary at the remaining dispense stations.

5.Exit the “Pump Speed Programming” mode by simultaneously pressing both “Hidden Switches”. Note that the beeper sounds twice and that the “PROGRAM” indicator extinguishes.

NOTE: Dispense at least 12 oz. of finished product before dispensing a sample to check brix. This will allow the pump time to adjust to the new speed.

Chilled Water Flow Testing and Adjustment

1.Enter the “Pump Speed Programming” mode by simultaneously pressing both “Hidden Switches”. Note that the beeper sounds twice and that the “PROGRAM” indicator begins flashing.

2.Place a graduated measuring cup or the large chamber of the empty brixing cup (BUNN-O-MATIC part number 33095.0000) under the appropriate dispense nozzle.

5.Measure the water dispensed. (Approx. 4.5 fl. oz. [133 ml])

6.If adjustment is required, remove all concentrate bottles from dispenser and disconnect any optional ambient concentrate hoses. Remove product shelf from dispenser.

7.Adjust the Chilled Water Flow Valve Fig 8, clockwise to decrease flow rate; counterclockwise to increase flow rate.

8.Repeat steps 3 through 6 as necessary until the desired water flow rate is achieved.

Note that if DIP switch #2 on the control board is set to the “on” position, concentrate must be present in order to dispense or program cup sizes.

3.Repeat as necessary for the remaining cup sizes and dispense stations.

4.Exit the “Cup Size Programming” mode by pressing any of the “+/STOP Switches”. Note that the beeper sounds twice and that the “PROGRAM” indicator extinguishes.
