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.

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.
