ADJUSTMENT & OPTIONAL SETTINGS

Total Dispense Ratio Set Up Procedure

1.Adjust water flow as described in Water Flow Testing and Adjustment. Record water output setting for later reference on each dispense head.

2.Enter program mode by simultaneously pressing both hidden switches.

3.Press and hold the dispense button, you will hear 5 beeps then two short beeps, continue holding until you hear three short beeps. At this time the dispenser will run product and water for 3 seconds.

4.Record the total ounces dispensed.

5.Refer to the Brix/Ratio chart below to confirm proper total dispensed amount for ratio desired and water output previously recorded.

6.To increase or decrease the product output, refer to Pump Speed Programming section. *

*Always dispense 12 ounces of finished product after making a pump speed adjustment before taking an ad- ditional sample for the brix/ratio check.

Temperature Compensated Refractometer Method

1.Adjust the water flow as described in Water Flow Testing and Adjustment.

2.Place an empty container under the appropriate dispense nozzle.

3.Dispensers with Press and Hold Feature:

Press and hold the “Product Dispense Switch” Fig 5, until water and concentrate begin flowing freely from the dispense nozzle.

Dispensers with Portion Control Feature:

Press and hold the “+/Stop Switch” Fig 6, until water and concentrate begin flowing freely from the dis- pense nozzle.

4.Discard the product caught previously and place the empty container back under the dispense nozzle.

5.Dispensers with Press and Hold Feature:

Press and hold the “Product Dispense Switch” until the cup is filled.

Dispensers with Portion Control Feature:

Press and hold the “+/Stop Switch” until the cup is filled.

6.Stir the contents of the cup, and use the refractometer (according to the manufacturer’s instructions) to check the brix %.

7.Adjust the pump speed (down to decrease the brix %; up to increase the brix %) to achieve the correct brix % as described in Pump Speed Programming.
