Each time the “Product Dispense” (“+/STOP”) Switch is pressed, the motor speed is decreased by one step (5 RPM.) Note that each step is confirmed by a single flash of the appropriate “REFILL” indicator and a single tone from the beeper.

4.Repeat as necessary at the remaining dispense stations.

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

NOTE: Dispense at least 12 oz. of finished product before dispensing a sample to check brix. This will allow the pump time to adjust to the new speed.
