ELECTRICAL HOOK-UP
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must provide electrical service as specifi ed.
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. Replace the right side access cover.
7. A qualifi ed Service Technician should now enter the Service Program mode under SELECT MACHINE VOLTAGE screen and choose “YES” (RIGHT) only if supplied voltage is above 220V.
NOTE: If plumbing is to be hooked up later be sure the brewer is disconnected from the power source. If plumbing has been hooked up, the brewer is ready for Initial Set-Up.

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
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 fi tting is
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
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 fl ow.
Building Codes in some areas require the installation of a back fl ow prevention device on branch water lines
that directly feed food and beverage equipment. The presence of a back fl ow 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
fl ow prevention device is present, Bunn-O-Matic recommends the installation of a water hammer arrester on
the incoming water line between the back fl ow 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.

This equipment must be installed to comply with the Basic Plumbing Code of the Building
Offi cials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation 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 HOOK-UP
1. Attach the fl ow control to fl are fi tting on bottom left side of brewer with copper tube assembly provided.
2. Flush the water line and securely attach it to the fl are fi tting on the water fl ow 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 fi tting in the back of
the drip tray to open up the drain hole. Connect drain line to the fi tting and run the line to the drain.

INITIAL SET-UP
1. Connect the brewer to the power source. The brewer will automatically begin to fi ll the tanks. After both tanks
are fi lled, the tank heaters will automatically turn on, one at a time. The dilution tank will heat fi rst, 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 fi lter/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.

COFFEE BREWING
1. Insert a fi lter into the funnel. BUNN® part number 20138.0000 (Gourmet) or equivalent.
2. Pour the proper amount of fresh ground coffee into the fi lter and level the bed of grounds by gently shaking.
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.
AUTOBREW
The brewer can be staged to automatically start a brew cycle when a reservoir reaches a low level.
