INTRODUCTION
This equipment will brew coffee into an awaiting Soft Heat (SH) Server. The
brewer may have an auxiliary hot water faucet. It is only for indoor use on a
sturdy and level counter or shelf. Please install in an area where there are
no water jet devices.
The Infusion Series, similar to the DBC Brew WISE, incorporates a wireless
interface system that allows the MHG or DBC Grinders 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 (half or full). 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.
The Infusion Series Coffee Brewer is able to brew coffee with recipe settings
and has the following features:
By-Pass, Pre-Infusion, Smart WAVE and Pulse Brew, Brew WISE, and LCD for
digital readout and programming along with the Smart Funnel and Server Detect
options for coffee. Other features are Energy Savings mode, BUNNlink
compatible, Smart Reader compatible, Freshness Timer and USB port for
operators to save and load recipes or new software onto brewer.

PLUMBING REQUIREMENTS
These brewers must be connected to a cold water system with operating pressure
between 20 and 90 psi (0.138 and 0.620 mPa) 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 (0.620 mPa) to
reduce it to 50 psi (0.345 mPa). The water inlet fitting is .75-11.5 NH (HOSE
THREAD). For convenience an elbow adaptor is provided to convert to a 1/4˝
flare fitting. Bunn-O-Matic does not recommend the use of a reverse-osmosis or
deionized water supply to this equipment. REQUIRED: 1.0 gpm (3.78 lpm) flow
rate from water supply line.
NOTE: Bunn-O-Matic recommends 3⁄8″ copper tubing for all installations from
the 1⁄2″ water supply line. A tight coil of tubing in the water line will
facilitate moving the brewer to clean the countertop. 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.
As directed in the International Plumbing Code of the International Code
Council and the Food Code Manual 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.

the funnel to the server. If bypass is used in a recipe, it will only turn on
after 30 seconds of sprayhood time. The operator will press SAVE to confirm
their entry, which will exit them back to the recipe parameter screen.
PRE-INFUSE – Pre-Infusion is defined as two parts; the first initial
wetting of the coffee grounds and the first initial “OFF” period before the
rest of the brew cycle begins. The operator will have the ability to brew with
just pre-infusion only, if they prefer to do so. The operator must enable the
feature by selecting the checkbox.
To set an “ON” time, the operator can select the text field. This will prompt
the numeric keypad to enter the desired time. To confirm a change, the
operator must press the SAVE button. The batch size icon in the upper right
hand corner of the screen will allow the operator to cycle between batch
sizes. If the operator switches to a different batch size, those parameters
must be updated in the fields. Disabling the feature will gray out the white
text fields. The operator will not be able to adjust this setting unless the
feature is enabled.
PULSE BREW – Pre-infusion and bypass settings will be taken into account
if set already. The operator will use the text fields to enter times. When
entering the sprayhood on time, the ounces or milliliters (depends on units
set on the machine) being dispersed for that amount of time will display. The
quantity of water dispersed will be larger the longer the time is on. If the
time is decreased, the volume should lower as well. The volume displayed will
be gathered from an average of both the left and right sprayhood calibration
settings. When setting the pause time, the operator is choosing how long to
turn the sprayhood off; this is not an accumulated time. This time is the
length that the sprayhood will turn off during the pulse routine then turn
back on. Both on and off times will have limits the operator is able to set
depending on the parameters of the recipe. When configuring the routine, the
total brew time will change to be shorter or longer depending on the routine
settings. Longer pause times extend total brew time in most cases. The Auto
calculate button will automatically set a routine based on the parameters for
the recipe. Save will confirm and save the settings for that recipes batch
size. The batch size icon will cycle through the other enabled sizes to allow
the operator to set the pulse brew for a different size batch from this
screen.
Auto Pulse Brew – An auto pulse brew is a set routine of 7 pulses that
has been calculated by parameters the operator has set. The operator must
specify the batch volume, percentage of bypass, pre-infusion time, and drip
time. The pulse off time is calculated off a 60 second additional Brew time
for the 6 off pulses between the 7 on pulses. Off time = 10 sec / pulse = 60
sec / 6 pulses
Manual Pulse Brew – If a operator would like to adjust the brewing time
which they have been given in Auto pulse, they can change or make adjustments
to the remaining on/off times. Doing this can extend or shorten the brew time
originally calculated for the Auto Pulse brew thus the operator is now going
to control what on and off times the brewer will use to make a pulse routine.
SMARTWAVE ® – This is a brewing feature that alters the trajectory of
water coming out of the sprayhood in order to enhance uniformity of
extraction. This is accomplished by activating the air pump during the
sprayhood on times only. When the sprayhood valve is on, the air pump will
activate and blow a pulse of air which will widen the pattern of water that
hits the bed of coffee. The operator will be able to set the Smart WAVE from
1-14. The plus/minus buttons will increment and decrement by 1. Each number
represents the air pump turning on twice during that brew cycle. 1 (2) – 14
(28). There will always be a blowout period of 5 seconds at the end of the
brew. This will evacuate water in the sprayhood to help avoid lime build up.
DRIP TIME – Drip time is the time allotted to allow for any excess coffee
to drip from the funnel after a brew has been completed. The operator will be
able to add up to 5 minutes worth of time. If no time is added the brew will
complete and funnel locks will raise.
FRESHNESS – This time is used to help control beverage quality. An alert
will pop-up full screen and state that the recipe has expired. Once
acknowledged, the operator can brew as normal.
REVIEW – Selecting this icon will give the operator another method of
setting a recipe. This method uses a table layout that shows the parameters
and the values that are set. Selecting the white area will take the operator
directly to the edit page for that parameter. The operator can change the
value, SAVE, and exit back to the recipe review screen.

Brew Settings
Accessed from MACHINE SETTINGS, there are several adjustable settings shown
within the Brew Settings option.
Brew Mode:
COLD Brew Mode enables operators to craft a batch of concentrate or ready-to-
drink cold brew quickly and consistently. When enabled, COLD Brew Mode uses a
range from high or ambient temperatures (100°F-120F°) and will populate the
recipe menu with default cold brew recipes. A tank purge will begin if
changing from HOT Brew to COLD Brew Mode.
HOT Brew Mode enables the operator to craft and dispense ready-to drink hot
brewed coffee quickly and consistently. When enabled, HOT Brew Mode uses a
range of high temperatures (140°F-207°F) and will populate the recipe menu
with default hot brewed coffee recipes.
Tank Set: The TANK SET is a temperature setting for water inside the
tank. The value entered and saved will be used as the default temperature for
brewing coffee. Minimum and maximum temperature ranges are dependent on Brew
Mode that is selected.
Lowest Recipe Temp: When COLD brew is selected along with enabled RECIPE
TEMPERATURE, the TANK SET will change to LOWEST RECIPE TEMP. Adjust the
setting to specify the lowest temperature that will be used for recipes.
Ready Temp: The READY TEMP is the lowest temperature required for the
water inside the tank before the machine can brew coffee. This option is only
available when BREW LOCKOUT is enabled.
Ready Within: When COLD brew is selected along with enabled RECIPE
TEMPERATURE and BREW LOCKOUT, the READY TEMP will change to READY WITHIN.
Adjust this setting to specify the number of degrees from the LOWEST RECIPE
TEMP that is required before the machine can brew coffee.
Brew Lockout: If BREW LOCKOUT is enabled, the machine will not allow
coffee to be brewed until the water inside the tank reaches a minimum
temperature specified within the READY TEMP. If BREW LOCKOUT is disabled, the
READY TEMPERATURE is greyed out and the button will become inactive.
Recipe Temperature: This feature allows the user to individually set
target brewing temperatures for each recipe. Recipe Temperature must be
enabled before the option appears in RECIPE EDIT. When enabled, the the
machine will only show recipes that pertain to the selected brew mode. For
instance, if Cold Brew is selected with Recipe Temperature enabled, the
machine will not display recipes for Hot Brew Mode in other menus or home
screen. When Recipe Temperature is disabled, both Hot and Cold Mode recipes
will be shown in other menus.
