ELECTRICAL REQUIREMENTS
WARNING - The brewer must be disconnected from the power source until specified in Initial Set-Up.
Refer to Data Plate on the Brewer, and local/national electrical codes to determine circuit requirements.
Requirements for brewers without an attached cord set are as follows:
L2 WHITE/VIOLET
120 V.A.C.
WHITE
208 OR 240 V A.C.
NEUTRAL
120 V.A.C.
L1 BLACK
P1841
120/208 & 120/240 volt ac models
Note: This electrical service consists
of 3 current carrying conductors
(Neutral, L1 and L2) and a separate
conductor for earth ground.
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 front panel beneath the sprayheads.
4. Feed the cord through the strain relief and connect it to the terminal block.
5. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding.
Replace the front panel.
6. 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 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 3⁄8" 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 counter top. 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.
AsdirectedintheInternationalPlumbingCodeoftheInternationalCodeCouncilandtheFoodCodeManual
of the Food and Drug Administration (FDA), this equipment must be installed with adequate backflow
prevention to comply with federal, state and local codes. For models installed outside the U.S.A., you
must comply with the applicable Plumbing /Sanitation Code for your area.
PLUMBING HOOK-UP
1. Flush the water supply line and securely attach it to the flare fitting or adapter located on rear of brewer.
2. Turn on the water supply.
INITIAL SETUP
CAUTION: The brewer must be disconnected from the power source throughout the initial setup, except when
specified in the instructions.
1. Insert an empty funnel into the funnel rails of one of the brew stations.
2. Place an empty server under the funnel.
3. Connect the brewer to the power source. Main ON/OFF Switch (located in bottom cover behind right front
leg on some brewers) must be in the ON position. Water will begin flowing into the tank and stop when the
tank is filled to its capacity. Display will show PLEASE WAIT...TANK FILLING until tank is filled with water.
4. Wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Display will
show READY TO BREW...WATER TEMP: XXX˚ when tank is at operating temperature.
NOTE: Brew water temperature is factory set at 200° F (93.3° C). Areas of high altitude will require lowering
this temperature to prevent boiling. Refer to chart in "SET TEMP" section when readjusting the brew
temperature.
5. Place a small vessel beneath the faucet and open the faucet handle. Release it when you hear the tank
refilling.
6. Water volumes have been preset at the factory. Refer to adjustments for the Set Brew Volumes section of
this manual should the volume need to be increased or decreased.
7. The brewer is now ready for use in accordance with the coffee brewing instructions.

OPERATING CONTROLS
(a) MAIN ON/OFF SWITCH
This switch, located under the brewer behind the right front leg, turns power on and off to all components
in the brewer.
(b) BATCH SELECTOR SWITCHES
Pressing the switch corresponding to the Small, Medium, or Large batch selects the amount of coffee to be
brewed. Pressing a different switch after a brew cycle has been initiated does not change the brew batch in
progress. Light indicates the selected batch to brew.
(c) ON/OFF SWITCH (ENABLE BREW)
Pressing the ON/OFF switch alternately turns the brewing side on and off. Pressing this switch during the brew
cycle will interrupt the brew cycle, stopping the flow of water. Pressing this switch during the programming
of the brewer will exit the setup and return to the main screen.
(d) BREW SWITCH
Momentarily pressing and releasing this switch begins a brew cycle.
(e) PROGRAM SWITCH
Pressing and holding the upper right hidden switch allows entry to the programming menus. Pressing and
releasing the switch steps through each function screen during programming.
(f) FUNCTION SCREEN
This is the display which shows the various functions of the brewer and allows the programming to be ac-
complished.
(g) FUNCTION SCREEN SWITCHES
These are the hidden switches which are used to program the brewer.
(h) FUNNEL SENSING COILS
These are used to "receive" information from the Smart Funnel handle (coffee name and batch size), and also
from RECIPE CARDS.
(j) SCROLL BACKWARDS
The upper left hidden switch can be used to scroll backwards through the function list.

COFFEE BREWING
1. Select the desired batch size on the grinder. It is not necessary to select a size on the brewer.
2. Insert a BUNN filter into the funnel.
3. Pour the proper amount of fresh ground coffee into the filter and level the grounds by gently shaking.
4. Slide the funnel into the funnel rails. If the grounds are not obtained through a grinder compatible with a
Smart Funnel, a batch size must be chosen on the brewer.
5. Place an empty server under the funnel.
6 The ENABLE BREW switch must be ON. Momentarily press and release the BREW switch. If the brewer has
the funnel lock option and if it is activated, once a brew cycle has been started the funnel is locked in place.
There may be certain situations in which the brew cycle will not begin when the BREW switch is pressed:
a) BREW TEMPERATURE TOO LOW - wait until heated or cancel BREW LOCKOUT option.
b) FUNNEL NOT IN PLACE (or using a standard brew funnel) - cancel FUNNEL DETECT option.
c) CHECK FUNNEL - remove funnel, empty previously brewed grounds and grind a new batch into the
funnel.
7. If none of the above messages are displayed, the display will read NOW BREWING and the time remaining
in the brew cycle. Arrows will point to the side which is brewing. If both sides are brewing simultaneously,
the arrows will alternate from left to right on the display.
8. Following the BREW will be a countdown of drip time DRIPPING which shows the time remaining until the
funnel lock will release. Discard the grounds and filter only after visible dripping stops.
CLEANING
1. The use of a damp cloth rinsed in any mild, nonabrasive, liquid detergent is recommended for cleaning all
surfaces on Bunn-O-Matic equipment.
2. Check and clean the sprayhead. Use the pointed end of sprayhead cleaning tool (#38227.0000) to remove
any mineral deposits from the sprayhead holes.
3. Insert the long end of sprayhead cleaning tool into the sprayhead fitting, and rotate several times to remove
any mineral deposits from the fitting.
4. Insert the short end of sprayhead cleaning tool into the bypass fitting, and rotate several times to remove
any mineral deposits from the fitting.
NOTE: In hard water areas, this may need to be done daily. It will help prevent liming problems in the brewer
and takes less than a minute.
