Water Flow Testing and Adjustment
NOTE: Purge all dispense stations to remove air from water line before making initial 
adjustments.
1.  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. 
Place the Program switch in the ON position.

2.  Press and release the desired “Product Dispense Switch” three times.(On Portion 

Control models, use the plus/stop switches)

3.  The selected position will dispense water (no concentrate) only for 3 seconds.
4.  Measure the water dispensed. Suggested target is 3 ounces (1 ounce per second 

flow rate.

5.  Adjust the water flow rate Fig 17, (clockwise to increase flow rate; counterclockwise 

to decrease flow rate) to the corresponding product mix ratio. Chart below provides 
general brix instructions.

P3586

6.  Repeat steps 1 through 5 as necessary until the correct water flow rate is achieved.
7.  Repeat steps 1 through 5 for the remaining dispense positions.
8.  Place the Program switch back into the OFF position.
Pump Speed Adjustment
1.  Disconnect the dispenser from the power source.
2.  Remove the drip tray.
3.  Remove the two screws securing the splash panel and remove the splash panel
4.  Locate the adjustment knobs on the circuit board.
NOTE: Start with the adjustment dial in the nine o'clock position.
5.  Turn the adjustment knobs clockwise to increase speed and counterclockwise to decrease speed.
NOTE: If splashing occurs while dispensing, reduce water flow rate. Then re-adjust pump speed to achieve proper ratio/
brix target.
6.  The knob positions directly correspond to dispense station locations.
NOTE: Some 2S models have 4 adjustment knobs on the circuit board. For these models use the two left most knobs to 
make pump speed adjustments. Left most being station #1 (left side dispense) and left center being station #2 (right side 
dispense).
7.  Reinstall the splash panel and drip tray and reconnect the dispenser to the power source.
