Water Flow Testing and Adjustment
1. Place a graduated measuring cup or the large chamber of the empty
brixing cup (BUNN-O-MATIC part number 33095.0000) under the ap-
propriate 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.
5. Adjust the water flow rate Fig 17, (clockwise to increase flow rate;
counterclockwise to decrease flow rate) to the corresponding product
mix ratio as follows:

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.
5. Turn the adjustment knobs clockwise to increase speed and counterclockwise to decrease speed.
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.
