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 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.

GLOSSARY
AD CARD: An assembly consisting of a computer chip (TAG) and an instruction label. Used for loading advertis-
ing 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.
CYCLE TIME: The total length of time to complete a brew cycle. Does not include Drip Time.
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 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.
INITIAL ON-TIME: During a pulse brew, this is the time set for the initial flow of water over the grounds.
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.
NO-NAME COFFEE: The term for the recipe used by the brewer when there is no coffee name stored in the funnel.
The brewer can contain separate No-Name recipes for the left and right brewing positions.
OFF-TIME: During a pulse brew or preinfusion, this is the time set for the length of time that the water is not
spraying over the grounds.
PREINFUSION: The process of beginning a brewing cycle with an initial spray of water onto the grounds followed
by a pause in the spray. After the programmed pause, the spray continues without interruption until the
end of the brewing cycle.
PULSE BREW: The process which allows the brew water to start, then stop, repeatedly, over the grounds in order
to derive the best flavor from the coffee. Pulse brew is also used in some instances to prevent a funnel
overflow.
RECIPE: Set of brewing parameters stored in the brewer. The parameters are unique for each coffee name and
include brew ounces, pulse brew, percent bypass, preinfusion and drip time.
RECIPE CARD: An assembly consisting of a computer chip (TAG) and an instruction label. Used for loading a
recipe into the brewer and the companion BrewWISE Grinder.

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 flavors 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 specifications.
PROGRAMMING SWITCHES
To access the programming mode, and to scroll through the different function screens, hidden programming
switches are used. There are five of these switches that will be used for the setup of the brewer.

IMPORTANT PROGRAMMING NOTES
- READ CAREFULLY -
To exit the programming mode at any time, press and release the ON/OFF switch (either on DUAL brewers)
located on the front switch panel. The display will return to the MAIN SCREEN.
If none of the five programming switches are pressed within one minute during the setup of the brewer,
the programming of the function screen that is being set will be exited and the display will return to the MAIN
SCREEN.
Always remember to place a container and funnel under the sprayhead(s) when operating the brewer during
the set-up of PULSE BREW - SET BY EXAMPLE, CALIBRATE FLOW and testing the brew and bypass valves in
SERVICE TOOLS/TEST OUTPUTS.
MAIN SCREEN
READY TO BREW
WATER TEMP: 200°
This screen will be shown when the brewer is ready
for use. The screen displays the water temperature
in the tank. When the water in the tank reaches the
correct set temperature, the display will change from
HEATING to READY TO BREW.
PROGRAMMING LOCKOUT SWITCH (mounted on
main control board)
This switch can be set to prevent access to the
programming levels of the brewer. Once all the correct brew settings are programmed, the operator can
set the switch to the "DISABLE" position to prohibit
anyone from changing the settings.

PROGRAMMING THE BREWER (cont.)
RECIPE PROGRAMING METHODS
There are three methods of programming the various brewing parameters of the SINGLE/GPR DBC or
DUAL/GPR DBC 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 funnel
rails (left side for DUAL brewers). 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 on DUAL brewers),
in the event a Smart Funnel and/or a G9-2T DBC or
MHG is not used with the SINGLE/DUAL/GPR 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
BREW VOLUMES, BYPASS PERCENTAGES, PULSE
BREW TIMES, PREINFUSION TIMES and DRIP-OUT
TIMES for the three batch sizes.
