INTRODUCTION
This 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 the name
of the coffee ground and what batch size will be brewed (small, medium, or large). Once the correct 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 coffee name 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 name to be brewed.

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 the brew station.
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. Insert a BUNN filter 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 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 funnel.
d) SERVER NOT IN PLACE - place Soft Heat Server, or cancel SERVER DETECT option.
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 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.

PROGRAMMING THE BREWER (cont.)
PROGRAM FUNCTIONS - LEVEL 2
METHOD 2:
Using a RECIPE CARD to enter all of the brew settings at one time:
If using a coffee flavor not in the G92T 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 name
of the coffee, BREW VOLUMES, BYPASS PERCENTAGES, PULSE BREW TIMES, PREINFUSION TIMES,
and DRIP-OUT TIMES.
There are three methods of programming the
various brewing parameters of the SINGLE SH with
Smart Funnel® Brewer.
METHOD 1:
Using a Smart Funnel and a G92T DBC Grinder:
Certain coffee NAMES are stored in the G92T
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 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 3:
Not using a Smart Funnel and/or a G92T DBC
Grinder:
This allows the operator to enter ONE set of brewing parameters in the event a Smart Funnel and/or a
G92T DBC is not used with the SINGLE SH Brewer.
This is referred to as a NO NAME coffee flavor. If the
brewer does not read the information in the funnel
handle, it automatically selects the NO NAME brewing
parameters set up prior to brewing. This includes the
BREW VOLUMES, BYPASS PERCENTAGES, PULSE
BREW TIMES, PREINFUSION TIMES and DRIP-OUT
TIMES for the three batch sizes.

PROGRAMMING FUNCTIONS - LEVEL 2 (cont.)
SET NEW RECIPE
Using a Smart Funnel and a G92T 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 G92T
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 TEMPERATURE, READY
TEMPERATURE, BREW LOCKOUTS, etc. Each coffee

set up that particular coffee name. The information
from the RECIPE CARD is loaded into the grinder's
memory, then into the brewer's memory by holding
the recipe card up to the equipment's sensing coil.
This information can include the coffee name, BREW
VOLUMES, BYPASS PERCENTAGES, PULSE BREW
TIMES, PREINFUSION TIMES and DRIP-OUT TIMES
for that particular coffee NAME. These can all be loaded
in seconds.
Contact Bunn-O-Matic Corporation for the availability of RECIPE CARDS.

SET NEW RECIPE:
If not using a Smart Funnel (with a sensor coil) and/
or a G92T DBC Grinder, the brewer will function as
a standard BUNN Single Brewer:
It is possible to operate the brewer without using a
Smart Funnel and/or a G92T DBC Grinder. If a standard
funnel, or if a non-DBC grinder is used the brewer will
automatically select a NO NAME coffee flavor when
pad is pressed. This means that no name was
the
read from the funnel's handle.
There is a NO NAME coffee program that can be
set in the brewer. This includes BREW VOLUMES,
BYPASS PERCENTAGES, PULSE BREW TIMES, PREINFUSION TIMES and DRIP-OUT TIMES. The brewer
will perform in the same capacity as a standard BUNN
SingleTM Brewer.
The instructions for programming the NO NAME
settings are on the following pages. The same steps
are followed for setting the recipe as those that are
used to MODIFY A RECIPE, beginning on page 19.
Note that when the display reads NO NAME, that
is when MODIFY should be pressed in order to set the
parameters for the NO NAME coffee.
NOTE: Before beginning setup, insert a funnel into
the funnel rails, and place a Soft Heat Server beneath
the brew funnel.

•
•
•
Inspection, testing, and repair of electrical equipment should be performed only by qualified
service personnel.
All electronic components have 120 - 240 volt ac and low voltage dc potential on their terminals.
Shorting 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 for more than ten minutes without a supply of water.
The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened.
This will help avoid twists and kinks in the tubing.
Make certain that all plumbing connections are sealed and electrical connections tight and isolated.
This brewer is heated at all times. Keep away from combustibles.
Exercise extreme caution when servicing electrical equipment.
Disconnect the brewer from the power source when servicing, except when electrical tests are specified.
Follow recommended service procedures.
Replace all protective shields or safety notices.

3. Refill Probe or Sensitivity Setting
Check the sensitivity setting. Refer
to the Refill function on page 28.
If the left three digit number is less
than the right number, the machine
“thinks” it is full and the refill valve
should be off. If the left number is
larger than the right, then the refill
valve will automatically be turned
on to fill the tank. The right number
is the threshold setting and can be
adjusted to compensate for extreme
water conditions: very pure, low
conductance water requires a higher
setting, while high mineral content,
high conductance water requires
a lower setting. Note that the left
number changes from a high value
when water is NOT touching the refill
probe to a low value when water IS
touching the probe. For best operation, the right number should be set
to a value midway between these low
and high numbers. Before changing
the setting, confirm that the refill
probe is free of scale buildup and the
connection to it is secure.
4. Refill Valve
Test the Refill valve. Refer to Testing
Individual Components on page 33.
5. Overflow Protection Switch

the triac is defective. If very low, or
zero voltage is measured, there could
be a defective triac or a defective
control board.
4. Electronic Control Board
Perform the above procedure for
testing triacs. If the voltage measured is very low or zero, then
substitute a control board known to
be in good working order.
