ADJUSTMENT & OPTIONAL SETTINGS (cont)

Water Flow Testing and Adjustment

1. Enter the “Pump Speed Programming” mode by simultaneously press- ing both “Hidden Switches” Fig 5 or Fig 6. 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 5 (“+/Stop Switch” Fig 6, 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 seconds.

5.Measure the water dispensed.

6.Adjust the water flow rate Fig 8, (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 fluid ounces (111 ml)	Prune Juice	16.0%
	per 3-second test	Other	*
4+1		Orange Juice	11.8%
		Pineapple Juice	12.8%
	*4.0 fluid ounces (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 fluid ounces (118 ml)	Other	*
	per 3-second test
High Viscosity Juice	2.25-3.0 fl.oz. (66.5-89ml)	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.
