INTRODUCTION
The brewer incorporates a wireless interface system that allows the DBC Grinder to load certain information
into the "programming tag" located inside the handle of the funnel. This information includes what flavor of coffee
is being ground and what batch size will be brewed (small, medium, or large). Once the correct flavor name and
amount of coffee is ground, the funnel is loaded into the brewer. The information from the funnel handle is then
transferred into the brewer. The brewer then takes this information and dispenses the amount of water preset in
the brewer for that particular flavor of coffee and batch size. The brewer can also be programmed to adjust different
functions of the brewing process, such as brew temperature, brew volumes, bypass percentages, pulse brew, etc.
This allows the operator to program a certain "recipe" for each coffee flavor to be brewed.

.
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 or female quick connect.
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.
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 Sanitation Manual of the Food and Drug Administration (FDA).
PLUMBING HOOK-UP

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. 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.
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.
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. Grind the selected amount of fresh coffee into the Smart Funnel® using the G9-2T DBC with Smart Funnel
operation and level the grounds by gently shaking.
4. Slide the funnel into the funnel rails. The brewer will read the size ground through the chip in the funnel handle
and will automatically select the correct size to brew. 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 Momentarily press and release the pad. 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 is pressed:
a) BREW TEMPERATURE TOO LOW - wait until heated or cancel BREW LOCKOUT option. (Page 10)
b) FUNNEL NOT IN PLACE (or using a standard brew funnel) - cancel FUNNEL DETECT option. (Page 31)
c) CHECK FUNNEL - remove funnel, empty previously brewed grounds and grind a new batch into the funnel.
d) SERVER NOT IN PLACE - place Soft Heat® Server, or cancel SERVER DETECT option. (Page 32)
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. The sprayhead holes must always remain open.
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.

GLOSSARY
AD CARD: An assembly consisting of a computer chip and an instruction label. Used for loading advertising
messages into the brewer.
BREW LOCKOUT: The inability to initiate a brew if the water temperature is less than the ready temperature
programmed into the brewer.
BYPASS: The process of diverting a portion of the brew water to the outside of the paper filter so that it does not
pass through the coffee grounds. This process is sometimes used to optimize the flavor of the finished
brew.
CHIP: A computer chip containing either recipes for specific coffee flavors or advertising messages which are
read by the sensing coils on the brewer. One chip is embedded in each Smart Funnel® handle to carry the
coffee flavor name and batch size ground from the grinder to the brewer.
DRIP TIME: The length of time from when the water spray over the grounds ends, to the time that no water drips
from the funnel tip.
FACTORY DEFAULTS: The factory preset brew settings that were installed into the brewer's memory.
FIRST ON-TIME: During a pulse brew or preinfusion, this is the time set for the initial flow of water over the
grounds.
FUNNEL DETECT: Sets the inability to initiate a brew cycle if the funnel is not properly inserted into the funnel
rails.
FUNNEL SENSING COIL: A sensor on the front hood of the brewer, which reads what name and batch size of
coffee was ground into the funnel and allows for the brewer to automatically set itself to what is read from
the funnel handle.
LAST ON-TIME: During a pulse brew, this is the time set for the second on-time, and each alternating on-time for
the remainder of the brew cycle.
MAIN SCREEN: The term used to describe the screen that is displayed when the brewer is not in use. This screen
is also displayed after exiting the programming mode.

PROGRAMMING THE BREWER (cont.)
PROGRAM FUNCTIONS - LEVEL 2
There are three methods of programming the
various brewing parameters of the Dual
®
Smart Funnel
Brewer.
®
SH with
METHOD 1:
Using a Smart Funnel
®
and a G9-2T DBC Grinder:
Certain coffee NAMES are stored in the G9-2T
DBC's memory. When a particular name of coffee is
ground into the Smart Funnel®, that name and the
batch size selected are transferred from the grinder to
the programming chip located in the funnel's handle.
The funnel is then inserted into the brewer's left side
funnel rails. The sensor coil on the brewer reads the
information contained in the handle. This then allows
the operator to set the BREW VOLUMES, BYPASS
PERCENTAGES, PULSE BREW TIMES, PREINFUSION
TIMES and DRIP-OUT TIMES for that particular coffee
NAME. Each coffee NAME can be set individually to
provide optimum brewing quality.
METHOD 2:
Using a RECIPE CARD to enter all of the brew
settings at one time:
If using a coffee name not in the G9-2T DBC's
memory, the customer can obtain a RECIPE CARD
from the factory with all the information needed to set
up that particular coffee flavor. This includes the
COFFEE NAME, BREW VOLUMES, BYPASS PER-
CENTAGES, PULSE BREW TIMES, PREINFUSION
TIMES, and DRIP-OUT TIMES.
METHOD 3:
Not using a Smart Funnel® and/or a G9-2T DBC
Grinder:
This allows the operator to enter ONE set of
brewing parameters for each side, in the event a Smart
Funnel® and/or a G9-2T DBC is not used with the Dual
SH Brewer. This is referred to as a NO NAME coffee
flavor. If the brewer does not read the information in
the funnel's handle, it automatically selects the NO
NAME brewing parameters set up prior to brewing.
This includes the BREW VOLUMES, BYPASS PER-
CENTAGES, PULSE BREW TIMES, PREINFUSION
TIMES and DRIP-OUT TIMES for the three batch sizes.
®
Page 11
29877 121302
PROGRAMMING FUNCTIONS - LEVEL 2 (cont.)
SET NEW RECIPE
Using a Smart Funnel® and a G9-2T DBC Grinder:
This function allows the operator to set BREW
VOLUMES, BYPASS PERCENTAGES, PULSE BREW
TIMES, PREINFUSION TIMES and DRIP-OUT TIMES
for each coffee name preset in the grinder's memory.
Certain coffee NAMES are stored in the G9-2T
DBC's memory. When a particular name of coffee is
®
ground into the Smart Funnel
, that name and the
batch size selected are transferred from the grinder to
the programming chip located in the funnel handle.
The funnel is then inserted into the brewer's left side
funnel rails. The sensor coil on the brewer reads the
information contained in the handle. The name of the
coffee flavor will then appear on the display. This then
allows the operator to set the BREW VOLUMES,
BYPASS PERCENTAGES, PULSE BREW TIMES, PREINFUSION TIMES and DRIP-OUT TIMES for that
particular coffee NAME. It also allows the operator to
set other brewing parameters, such as BREW TEM-
PERATURE, READY TEMPERATURE, BREW LOCKOUTS, etc. Each coffee NAME can be set individually
to provide optimum brewing quality.
Procedure for Setting the Recipe:
NOTE: Before beginning setup, place a server beneath
the left brew funnel.
1. Insert the funnel into the grinder and select a batch
size to grind. It is not necessary to have coffee
beans in the hopper(s) in order to program the
brewer. The coffee name is pre-selected and stored
in the grinder's memory for the side being ground.
2. Press the
pad. When the grinder stops grind-
ing, remove the funnel.
3. On the brewer, press and hold the ® pad until the
display reads SET NEW RECIPE. Release the ®
pad.
4. Press and release YES. The display should read
INSERT FUNNEL WITH NEW NAME, then USE
LEFT SIDE ONLY, and finally, QUIT SETUP? These
three displays will repeatedly cycle.
5. Insert the funnel into the rails on the left side of
the brewer. The display should read the NAME of
the coffee that was ground into the funnel, along
with a NO and YES. If the NAME on the display is
correct, press YES.
6. If, for some reason, the name of the coffee from
the grinder did not load properly into the funnel, or
if a grind has not yet been done, the display will
read MUST GRIND INTO FUNNEL FIRST. It will be
necessary to grind another batch following steps
1 and 2.
7. If the grind is acknowledged by the brewer, the
display will read BEGIN SETUP OF (COFFEE NAME).
Then the screen will display BREW OZ. and a batch
light will be blinking. (Refer to page 18 for description of BREW OZ. function).
