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.

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 replace the splash panel.

correct brix % as described in Pump Speed Adjustment.
Step 11: If customer has a BUNN water filtration system installed before the dispenser, replace the filter or filter car-
tridge.
