ADJUSTMENT & OPTIONAL SETTINGS (cont)

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.Place the Program switch in the ON position.

3.Place a measuring container under the dispense nozzle, press and release the DISPENSE button 6 times.

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 Adjustment section.

7.Place the Program switch back into the OFF position.

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.Press and hold the “Product Dispense Switch” Figs 9 & 10, until water and concentrate begin flowing freely from the dispense nozzle.

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

5.Press and hold the “Product Dispense 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 Adjustment.
