ADJUSTMENT & OPTIONAL SETTINGS (cont)

Water Flow Testing and Adjustment

1.Enter the “Pump Speed Programming” mode by simultaneously press- ing both “Hidden Switches” Fig 4 or Fig 5. 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 ap- propriate dispense nozzle.

3.Press and hold the desired “Product Dispense Switch” Fig 4 (“+/Stop Switch” Fig 5, for portion control dispensers) for 5 seconds. Note that the beeper sounds once per second (6 times, total) during this period.

4.At the end of the 5 second period, the selected position will dispense water (no concentrate) for only 3 sec- onds.

5.Measure the water dispensed.

6.Adjust the water flow rate Fig 7, (clockwise to increase flow rate; counterclockwise to decrease flow rate) to the corresponding product mix ratio as follows:

Mix Ratio	Adjust water flow rate to:	Product	Brix %
(water + concentrate)
2+1	*3.75 fl. oz (111 ml)	Prune Juice	16.0%
	per 3-second test	Other	*
4+1		Orange Juice	11.8%
		Pineapple Juice	12.8%
	*4.0 fl. oz (118 ml)	Cranberry Fruit Cocktail	14.0%
		Grapefruit Juice	10.6%
5+1	per 3-second test	Lemonade
		Apple Juice	12.0%
		Fruit Punch
		Grape Juice	13.0%
3+1 through 7+1		Other	*
Above 7+1	*4.0 fl. oz (118 ml)	Other	*
	per 3-second test
High Viscosity Juice	2.25 - 3.0 fl. oz (66.5 - 89 ml)	As Required	-
	per 3-second test

*Maximum flow rate may be less depending on the water pressure supply at each location.

Note: Information for specific products listed in this table is to be used for reference only. Consult the product label for exact mix ratio and/or brix %. See product label for target brix %.

7. Repeat steps 3 through 6 as necessary until the correct water flow rate is achieved.

8. Repeat steps 3 through 7 for the remaining dispense positions.

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

Pump Speed Programming

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.To increase the pump speed, press and hold the right-hand “Hidden Switch” (filled circle) and then momen- tarily press the “Product Dispense Switch” Fig 4 (“+/STOP Switch” Fig 5, for portion control dispensers). Each time the “Product Dispense Switch “(+/STOP Switch”) is pressed, the motor speed is increased by one step (5 revolutions per minute [RPM].) Note that each step is confirmed by a single flash of the appropriate “REFILL” indicator and a single tone from the beeper.
