6.If adjustment is required, remove all concentrate bottles from dispenser and disconnect any optional ambient concentrate hoses. Remove product shelf from dispenser.

7.Adjust the Chilled Water Flow Valve Fig 8, clockwise to decrease flow rate; counterclockwise to increase flow rate.

8.Repeat steps 3 through 6 as necessary until the desired water flow rate is achieved.

9.Exit the “Pump Speed Programming” mode by simultaneously

pressing both “Hidden Switches”. Note that the beeper sounds twice and that the “PROGRAM” indicator extinguishes.
