ADJUSTMENT & OPTIONAL SETTINGS (cont)
Temperature Compensated Refractometer Method
1. Adjust the water flow as described in Water Flow Testing and Adjustment.
2. Place an empty container under the appropriate dispense nozzle.
3. Press and hold the “Product Dispense Switch” Figs 9 & 10, until water and concentrate begin flowing freely from the dispense
nozzle.
4. Discard the product caught previously and place the empty container back under the dispense nozzle.
5. Press and hold the “Product Dispense Switch” until the cup is filled.
6. Stir the contents of the cup, and use the refractometer (according to the manufacturer’s instructions) to check the brix %.
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.
Optional Cold Water Flow Adjustment
Some dispensers are equipped with an optional cold water dispense valve. It is recommended to adjust the flow rate upon initial
set up of the dispenser. The adjustment for the cold water can be located inside the dispenser behind the right service panel.
The cold water dispense valve is mounted to the frame just above the ice bath. Attached to this valve is a needle type adjustment
valve. Turn the adjustment clockwise to decrease the water flow, and counter-clockwise to increase the water flow.
Dispenser Lockout
Dispense functions of the dispenser can be turned-off to prevent unauthorized use of the dispenser, while keeping
the refrigeration system running.
1. Locate the Dispense Lockout switch at the bottom front of the dispenser behind the drip tray.
2. Place the switch in the OFF position to prevent dispensing.
3. Place the switch in the ON position to allow dispensing.
NOTE: This switch will also operate the door lights on models equipped with this feature.

TROUBLESHOOTING
A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encountered.
If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service Department.
•
•
Inspection, testing, and repair of electrical equipment should be performed only by qualified service personnel.
All electronic components have 120-240 volt ac and low voltage dc potential on their terminals. Shorting of terminals
or the application of external voltages may result in board failure.
•
•
•
•
Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent. If an intermittent
condition is encountered, the cause will likely be a switch contact or a loose connection at a terminal or crimp.
Solenoid removal requires interrupting the water supply to the valve. Damage may result if solenoids are energized for
more than ten minutes without a supply of water.
The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will help to avoid
twists and kinks in the tubing.
Make certain that all plumbing connections are sealed and electrical connections tight and isolated.
WARNING – • Exercise extreme caution when servicing electrical equipment.
• Unplug the dispenser when servicing, except when electrical tests are specified.
• Follow recommended service procedures.
• Replace all protective shields or safety notices.
