PLUMBING REQUIREMENTS

This dispenser must be connected to a COLD WATER system with operating pressure between 20 and 100 psi (138
and 690 kPa). This water source must be capable of producing a minimum flow rate of 3 fluid ounces (88.7 milliliters) per
second. A shut off valve should be installed in the line before the dispenser. Install a regulator in the line when pressure is
greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). Also if the install location experiences pressure fluctuations
greater than 20 psi (138kPa). The main water inlet is a 3/8” (9.52 mm) male flare.
Additionally, the dispenser’s rinse connection may be connected to a HOT WATER system.
Caution: MAXIMUM RINSE WATER TEMPERATURE: 170 degrees F (76.6 degrees C)
Use BUNN-O-MATIC tubing, part number 34325.10_ _ (see Illustrated Parts Catalog for complete part number) for hot
water connection.
The rinse water operating pressure must be between 20 and 100 psi (138 and 690 kPa). A shut off valve should be
installed in the line before the dispenser. Install a regulator in the line when pressure is greater than 100 psi (690 kPa) to
reduce it to 50 psi (345 kPa). The rinse water inlet is a 3/8” (9.52 mm) barb connection.
NOTE- At least 18 inches (457 mm) of an FDA approved flexible beverage tubing, such as reinforced braided polyethylene,
before the dispenser will facilitate movement to clean the countertop. It can be purchased direct from BUNN-O-MATIC (part
number 34325.10_ _ [see Illustrated Parts Catalog for complete part number.]) BUNN-O-MATIC does not recommend the
use of saddle valves to install the dispenser. The size and shape of the hole(s) made in the supply line(s) by saddle valves
may restrict water flow.
NOTE- On early models dispensers without water inlet valve, a water strainer (Bunn-O-Matic part number 23720.1000)
should be installed in line, prior to the flexible water line. This strainer is supplied loose with the dispenser.
NOTE - Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed and
maintained in accordance with federal, state and local codes.

This equipment must be installed to comply with the International Plumbing Code of the International
Code Council and the Food Code Manual of the Food and Drug Administration (FDA). For models installed
outside the U.S.A., you must comply with the applicable Plumbing/Sanitation Code for your area.

PLUMBING HOOKUP
CAUTION: The dispenser must be disconnected
from the power source throughout the plumbing
hookup.
For early models without the water inlet valve,
plumbing connections are located behind the
dispenser’s splash panel. Hoses are connected to
the water valve(s) and travel under the water bath
tank and out the rear of the dispenser. A .38" female
flare connector is attached to the hose and connects
to the supplied water strainer. The water strainer
is shipped loose, taped to the bottom panel.
For late models with the water inlet valve, a
hose assembly from the water bath shut-off valve
travels over the top of the water bath tank to the
product coil and the water inlet valve. A .75" hose
to .38" male flare fitting attaches to the water inlet
valve.
To access the water valves in the front of the
dispenser, remove the drip tray assembly; remove
the two screws securing the splash panel to the
dispenser and remove the splash panel.

INITIAL FILL
CAUTION: The dispenser must be disconnected from the power source throughout the initial fill except when
specified in the instructions.
1. Remove drip tray assembly and splash panel from the dispenser. Set the drip tray back into place.
2. Ensure that the Main Water Valve (Early models) and the Water Bath Valve Fig 3, are turned off (handles positioned at 3 o’clock and 9 o’clock, respectively,) and that the Refrigeration Switch Fig 2, is in the OFF (rear)
position.
3. Turn on the water supply.
4. Connect the dispenser to the power source.
5. For late models with the water inlet valve, simultaneously press the two hidden switches (C, Figs 4 & 5) to
enter the program mode. This activates the water inlet valve at the rear of the dispenser and allows water to
flow to the water bath valve at the front of the dispenser.
6. While observing the water bath sight gauge (the clear tube located just to the left of the plumbing connections,) begin filling the water bath by rotating the handle of the Water Bath Valve counterclockwise to the 6
o’clock position. The dispenser will beep for three seconds when the bath is approaching full. Reduce the
flow rate at this time.
7. When the water level in the sight gauge comes within 1 inch (25.4 mm) of the clear plastic tee, reduce the
water flow by rotating the handle of the Water Bath Valve clockwise to the 8 o’clock position.
8. When the water in the water bath sight gauge begins to trickle down into the drip tray, turn the Water Bath
Valve off by rotating the handle clockwise to the 9 o’clock position.
9. After approximately 3 minutes (this allows the recirculating pump and cabinet cooling components an opportunity to fill with water,) top off the water bath tank by rotating the handle of the Water Bath Valve counterclockwise to the 8 o’clock position.
10. Again, when the water in the water bath sight gauge begins to trickle down into the drip tray, turn the Water
Bath Valve off by rotating the handle clockwise to the 9 o’clock position.
11. Place the Refrigeration Switch ON (forward.)
12. It will take approximately 4 hours at 70 degrees F (21 degrees C) ambient to create the ice bank required for
full dispenser performance. During this time, some further trickling from the water bath is expected due to
expansion caused by ice bank formation. While the refrigeration system is creating the ice bank, the dispenser
may be readied for use as described in Loading, Priming and Adjustment.
13. The dispenser will safely store concentrate once the “COOLING” indicator completely extinguishes (not lit
steadily or flashing.)
14. For early models, after the refrigeration compressor switches off, turn Main Water Valve on by rotating the
handle counterclockwise to the 12 o’clock position.
15. Replace the splash panel and drip tray assembly.
LOADING
Frozen Concentrates
1. Thaw the frozen concentrate in a refrigerated 35-40 degrees F (1.6-4.4 degrees C) environment for 36 to 48
hours before use.
2. Thoroughly mix the thawed concentrate by vigorously shaking the product container.
3. Open the dispenser door.
4. Prior to placing the product container in the dispenser, make sure that the o-ring on the container adapter is
lubricated. This will ease removal of the container when it becomes necessary.
5. Place the product container in the desired position and press it firmly into the bottle adapter opening.
6. Open the vent hole in the product container.
Note: Concentrate in the container must be completely thawed and be within the temperature range of 35-40
degrees F (1.6-4.4 degrees C.) Product outside of this temperature range, especially below, will produce an
“out of brix” drink.

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.
This brewer is heated at all times. Keep away from combustibles.

WARNING –
