□ Total Dispense Test

Step 1:Placethepitcherbeneaththedispensenozzleyouaretesting.

Step 2: Place the “Dispense Lockout” switch in the Off position and access the internal program switch and

turn ON.

Step 3: Press and release the dispense button, (“Stop/Plus” button if using portion control option), 6 times.

Step 4: Measure the amount of liquid dispensed.

Step 5: Mark the quantity of liquid dispensed on the total dispense ratio chart.

□ Pump Speed Adjustment

Step 1: Disconnect the machine from the power source.

Step 2: Remove the drip tray.

Step 3: Remove the splash panel by removing the screws holding it in place.

Step 4: Locate the adjustment knobs on the control board. Turn the knob, associated with the dispense

station you wish to adjust, clockwise to increase the pump speed and counterclockwise to decrease

the pump speed. Increasing the pump speed will increase the amount of product dispensed giving

you a higher total dispense, decreasing the pump speed will have the opposite affect.

Step 5: Conduct the total dispense test to determine if more of an adjustment is needed. If no further

adjustments are required, turn OFF the program switch and re-install the lower splash panel.

Step 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.
