ELECTRICAL REQUIREMENTS
WARNING - The dispenser must be disconnected from the power source until specified in Electrical Hook-Up.
The 120 volt version of this dispenser has an attached cordset. NOTE: If the power cord is damaged, it must be
replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard.
Refer to Data Plate on the Brewer, and local/national electrical codes to determine circuit requirements.
ELECTRICAL HOOK-UP
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must provide electrical service as specified.
2. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
3. Remove the right side access cover.
4. Feed the cord through the strain relief in the bottom right and connect it to the terminal block.
5. Connect the ground wire to the stud next to the terminal block and secure with #8-32 nut.
6. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding. Re-
place the right side access cover.
7. A qualified Service Technician should now enter the Service Program mode under SELECT MACHINE VOLT-
AGE screen and choose “YES” (RIGHT) only if supplied voltage is above 220V.
Note: This electrical service
consists of 2 current carrying
conductors (Neutral and L1)
and a separate conductor for
earth ground.
LOAD LOAD LOADLINE LINE LINE
NOTE: If plumbing is to be hooked up later be sure the brewer is disconnected from the power source. If plumb-
ing has been hooked up, the brewer is ready for Initial Set-Up.

PLUMBING HOOK-UP
1. Attach the flow control to flare fitting on bottom left side of brewer with copper tube assembly provided.
2. Flush the water line and securely attach it to the flare fitting on the water flow control.
3. Turn on the water supply.
4. Connect drain per instructions in the provided Drain Plumbing Kit.
5. The drip tray may also be connected to a drain. Run a 3/8” or 13/32” drill through the fitting in the back of
the drip tray to open up the drain hole. Connect drain line to the fitting and run the line to the drain.
PLUMBING REQUIREMENTS
This brewer must be connected to a cold water system with operating pressure between 20 and 90 psi (138
and 620 kPa) from a 1⁄2” or larger supply line. A shut-off valve should be installed in the line before the brewer.
Install a regulator in the line when pressure is greater than 90 psi (620 kPa) to reduce it to 50 psi (345 kPa).
The water inlet fitting is 1⁄4” flare.
NOTE – Bunn-O-Matic recommends 1⁄4” copper tubing for installations of less than 25 feet and 3⁄8” for more
than 25 feet from the 1⁄2” water supply line. A tight coil of copper tubing in the water line will facilitate moving
the brewer to clean the countertop. Bunn-O-Matic does not recommend the use of a saddle valve to install the
brewer. The size and shape of the hole made in the supply line by this type of device may restrict water flow.
Building Codes in some areas require the installation of a back flow prevention device on branch water lines
that directly feed food and beverage equipment. The presence of a back flow prevention device can result in an
increase in water pressure that prevents the proper operation of the machine’s water inlet solenoid. When a back
flow prevention device is present, Bunn-O-Matic recommends the installation of a water hammer arrester on
the incoming water line between the back flow prevention device and the machine. Water hammer arresters are
available through a local plumbing supply house or directly from Bunn-O-Matic by ordering Bunn-O-Matic Part
Number 29350.0000 or 28919.0000.
35352 121405
This equipment must be installed to comply with the Basic Plumbing Code of the Building
Officials and Code Administrators International, Inc. (BOCA) and the Food Service Sanita-
tion 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.

INITIAL SET-UP
1. Connect the brewer to the power source. The brewer will automatically begin to fill the tanks. After both tanks
are filled, the tank heaters will automatically turn on, one at a time. The dilution tank will heat first, then the
brew tank. The tanks are fully heated when the BREWER READY indicator light is illuminated.
2. About 5 seconds after the brewer is connected to the power source, the LEFT/RIGHT LOW indicator lights
will illuminate. If a funnel is in place, the DISPOSE GROUNDS indicator will also be illuminated. Removing
the funnel for at least two seconds will reset this indicator.
OPERATING CONTROLS
1. BREWER READY INDICATOR
Indicates the water in the brew tank has reached the acceptable target temperature for brewing coffee. The
machine will not allow brewing until the indicator is illuminated. This is known as “brew Lockout” and cannot
be disabled. (Heating times are longer for 120V machines)
2. SERVICE INDICATOR
Indicates the machine has malfunctioned and requires service or clean. View the display screen for the actual
fault code. To reset any fault, remove the funnel and press both LEFT and RIGHT start switches. If the fault
returns, refer to the service decal (typically located on inside panel of door).
3. DISPOSE GROUNDS INDICATOR
Indicates that a brew or clean cycle is completed. Pull the funnel out and dump the used filter/grounds (or
Cleaning Packet). The indicator resets when the funnel is removed.
4. AUTOBREW ON INDICATOR
Indicates that the brewer is in the autobrew mode and will automatically start another brew cycle when a
reservoir reaches a low level. When brew cycle is completed, DISPOSE GROUNDS indicator will illuminate.

AUTOBREW
The brewer can be staged to automatically start a brew cycle when a reservoir reaches a low level.
1. Repeat steps one through three above. When the appropriate button is pushed to start the brew cycle, the
green AUTOBREW ON indicator will light.
2. When the reservoir for which the brew cycle has been selected reaches the low level, the brew cycle will
automatically start, and the AUTOBREW ON indicator will reset.
3. To cancel the AUTOBREW mode before the brew cycle begins, remove the funnel from the brewer.
COFFEE BREWING
1. Insert a filter into the funnel. BUNN®part number 20138.0000 (Gourmet) or equivalent.
2. Pour the proper amount of fresh ground coffee into the filter and level the bed of grounds by gently shak-
ing.
3. Slide the funnel into the funnel rails, the arrow on the funnel handle towards the front of the brewer pointing
towards the left, for brewing into the rear reservoir, or with the arrow pointing to the right, for brewing into
the front reservoir.
4. Press the appropriate button, either LEFT or RIGHT to start the brew cycle.
5. When the brew cycle is complete, the DISPOSE GROUNDS indicator light will be illuminated. Dispose of used
grounds to reset the indicator. The (red) LEFT or RIGHT LOW indicator for the reservoir brewed into should
be extinguished.
NOTE: In order for the LEFT, RIGHT, and CLEAN switch to actuate on the Manual Control machines, the lower
“Hidden” switch to the right of the “RIGHT” switch must be pressed and held.

BASIC TROUBLESHOOTING
• Inspection, testing, and repair of electrical equipment should be performed only by qualified service person-
nel.
• All electronic components have 208/240 or 120 volt ac and low voltage dc potential on their terminals. Short-
ing 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 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 unit is heated at all times. Keep away from combustibles.
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
