INTRODUCTION
The brewer incorporates a wireless interface system that allows the DBC Grinder to load certain information
into the "programming chip" located inside the handle of the funnel. This information includes what fl avor of coffee
is being ground and what batch size will be brewed (small, medium, or large). Once the correct fl avor 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 fl avor 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 fl avor to be brewed.

INITIAL SETUP
CAUTION – The brewer must be disconnected from the power source throughout the initial setup, except when
specifi ed 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 fl owing into the tank and stop when the tank is
fi lled to its capacity. Display will show PLEASE WAIT...TANK FILLING until tank is fi lled 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 refi ll-
ing.
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. Insert a BUNN fi lter into the Smart Funnel.
2. If a grinder is not used to obtain the coffee grounds, pour the proper amount of fresh coffee grounds into
the funnel and level by gently shaking. Slide the funnel into the funnel rails and select batch size. Proceed to
step 5.
3. If a G9-2T DBC or MHG grinder is used with a compatible Smart Funnel, select the desired batch size on the
grinder. Grind the selected amount of fresh coffee into funnel and level grounds by gently shaking. It is not
necessary to select a size on the brewer.
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.
5. Place an empty server under the funnel.
6 The ON/OFF switch must be ON. Momentarily press and release the BREW switch. If the brewer has the fun-
nel 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 brew switch is pressed:
a) ON/OFF must be ON.
b) BREW TEMPERATURE TOO LOW - wait until heated or cancel BREW LOCKOUT option.
c) FUNNEL NOT IN PLACE (or using a standard brew funnel) - cancel FUNNEL DETECT.
d) CHECK FUNNEL - remove funnel, empty previously brewed grounds and grind a new batch into the fun-
nel.
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 DRIPPING time which shows the time remaining until the funnel
lock will release. Discard the grounds and fi lter 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. Do NOT clean this equipment with a water jet device.
2. Check and clean each sprayhead. The sprayhead holes must always remain open.
NOTE: Any buildup on the sprayhead and fi tting may restrict water fl ow, and impact your coffee brewing. For
consistently great coffee, clean sprayheads and fi ttings weekly with sprayhead cleaning tool (#38227.0000).
Upon visual inspection it may appear that light passes through all holes in the sprayhead plate, but a thin
fi lm of residue can pass light and still impede water fl ow.
3. Insert the long end of sprayhead cleaning tool into the sprayhead fi ttings, and rotate several times to remove
any mineral deposits from the fi tting.
4. Insert the short end of sprayhead cleaning tool into the bypass fi ttings, and rotate several times to remove
any mineral deposits from the fi tting.
5. Remove sprayheads from brewer. Disassemble by removing the seal.
6. Use the pointed end of sprayhead cleaning tool to remove any mineral deposits from the sprayhead holes.
7. Reassemble sprayheads and reattach. Sprayheads only needs to be hand tightened.
See page 35 of instruction manual for calibration routine to verify sprayhead fl ow rate matches programmed
fl ow rate. Machine may need to be re-calibrated due to lime build up. If machine is cleaned and build up
removed, machine must be re-calibrated to achieve desired volumes.

PROGRAMMING
Using the menu-driven display on the front of the brewer, the operator has the ability to alter or modify various
brewing parameters such as brew temperatures, brew volumes, bypass percentages, etc. This allows for the
precise brewing of various fl avors of coffee.
Programming of the brewer is achieved by entering a certain function. Then, by the use of hidden programming
switches, the operator can customize the brewing process to their specifi cations.
PROGRAMMING SWITCHES
To access the programming mode, and to scroll through the different function screens, hidden programming
switches are used. There are fi ve of these switches that will be used for the setup of the brewer.

PROGRAMMING THE BREWER (cont.)
PROGRAM FUNCTIONS - LEVEL 2
There are three methods of programming the
various brewing parameters of the Dual TF with Smart
Funnel Brewer.
METHOD 1:
Using a Smart Funnel and a G9-2T DBC or MHG
Grinder:
Certain coffee NAMES are stored in the G9-2T DBC
or MHG'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.
RECIPES
This diagram allows for the creating, modifying,
or viewing of recipes in the brewer.
METHOD 2:
Using a RECIPE CARD to enter all of the brew settings at one time:
If using a coffee name not in the grinder's memory,
the customer can obtain a RECIPE CARD from the
factory with all the information needed to set up that
particular coffee name. This includes the COFFEE
NAME, BREW VOLUMES, BYPASS PERCENTAGES,
PULSE BREW TIMES, PREINFUSION TIMES, and
DRIP-OUT TIMES.
METHOD 3:
Not using a Smart Funnel and/or a G9-2T DBC or
MHG 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 or MHG is not used with the Dual
TF Brewer. This is referred to as a NO NAME coffee
fl avor. 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 BREW VOLUMES, BYPASS PERCENT-
AGES, PULSE BREW TIMES, PREINFUSION TIMES
and DRIP-OUT TIMES for the three batch sizes.
