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.

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 reﬁll-

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 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.

RECIPE PROGRAMING METHODS

There are three methods of programming the various brewing parameters of the DUAL SH 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 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 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 BREW VOLUMES, BYPASS PERCENT-

AGES, PULSE BREW TIMES, PREINFUSION TIMES

and DRIP-OUT TIMES for the three batch sizes.

SET NEW RECIPE Using a Smart Funnel and a G9-2T DBC or MHG Grinder: This function allows the operator to set BREW VOLUMES, BYPASS PERCENTAGES, PULSE BREW 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, 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 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 GRIND switch. When the grinder stops

grinding, remove the funnel.

3. On the brewer, press and hold the upper right

hidden switch (®) until the display reads UNITS. Release the switch, then press switch again until display reads SET NEW RECIPE.

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 BREW OZ (SETTING OR ADJUSTING for description)

SET NEW RECIPES (cont.) SET NEW RECIPE: If not using a Smart Funnel (with a computer chip) and/or a G9-2T DBC or MHG Grinder, the brewer will function as a standard Bunn Dual Brewer:

It is possible to operate the brewer without using a Smart Funnel and/or a G9-2T DBC or MHG Grinder. If a standard funnel, or if a non-DBC grinder is used the brewer will automatically select a NO NAME coffee when the BREW switch is pressed. This means that no name was read from the funnel's handle. There are two NO NAME coffee programs that can be set in the brewer. They are referred to as NO NAME LEFT and NO NAME RIGHT. The left and right sides of the brewer can be set up independently of each other. This includes BREW VOLUMES, BYPASS

PERCENTAGES, PULSE BREW TIMES, and DRIP-OUT TIMES. The brewer will perform in the same capacity

as a standard Bunn Dual 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 21. Note that when the display reads NO NAME LEFT, that is when MODIFY should be pressed in order to set the parameters for the NO NAME LEFT coffee. Otherwise, press NEXT to display NO NAME

RIGHT.

At this point, MODIFY should be pressed in order to set the parameters for the NO NAME RIGHT coffee.

SET PULSE BREW:

This function allows the operator to program the brewer to "pulse” the sprayhead ﬂow on and off continually during a brew cycle (start and stop the ﬂow of water out of the sprayhead). This feature allows the ability to “ﬁne-tune” the brewer for speciﬁc ﬂavor proﬁles. Pulse brewing can be set up for any and all batches.

P2293

a) 1st ON TIME - This time is the duration from when

the BREW switch is pressed to when the desired water level in the funnel is reached. (Soaking the grounds)

b) OFF-TIME - This time is the duration from when

the water in the funnel reaches the desired ON TIME level to when it drains out of the funnel to a desired lower level.

c) LAST ON-TIME- This time is the duration from when

the water in the funnel drains down to the lower level to when it ﬁlls the funnel to a desired higher level. (Soaking the grounds).

These three times can be set two different ways. The ﬁrst is accomplished by utilizing the EASY PULSE screen and following the subsequent steps under that function. The other allows the actual times to be entered for each of the settings. This is done by utilizing the ENTER TIMES screen and following the subsequent steps under that function. Either of these methods can be used to set the pulse brew for each batch.

COPY SETTINGS (NO NAME COFFEE SETTINGS

ONLY)

This function is used to transfer all the brew set-

tings from a NO NAME coffee ﬂavor programmed on one side of the brewer to the other side. A NO NAME coffee is a ﬂavor that is not in the grinder's memory or is what appears if a Smart Funnel® is

not used. For example, once the left side's 3 batch sizes are programmed (brew volumes, bypass percentages, pulse brew times, pre-infusion times, and drip-out times) for a particular NO NAME coffee, all the data can be transferred from the left side of the brewer to the right side in one step. The data can also be transferred from right to left, if the right side had been the initial set-up side. This results in less set-up time. If two different NO NAME setups are required, one on the left, the other on the right side, it is not recommended that this function be used.

Procedure to copy settings:

1. Press and hold the upper right hidden switch until

the display reads UNITS. Release the switch. Con-

tinue to press and release switch until the display

reads COPY SETTINGS.

A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encountered. If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service Department.

• Inspection, testing, and repair of electrical equipment should be performed only by qualied

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 per-

manent. 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 sole-

noids are energized for more than ten minutes without a supply of water.

• The use of two wrenches is recommended whenever plumbing ttings 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 iso-

lated.

• This brewer is heated at all times. Keep away from combustibles.

WARNING

• 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.

Problem

Automatic reﬁll will not operate or display shows FILL TIME TOO LONG (cont.)

Possible Cause

3. Reﬁll Probe or Sensitivity Setting

Troubleshooting Procedure

Check the sensitivity setting. Refer to Reﬁll function. 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.

Water ﬂows into tank continuously with power removed from brewer.

Possible Cause

3. Triac

4. Electronic Control Board

Troubleshooting Procedures

Remove power from the brewer. Connect a voltmeter across one of the tank heaters. Reapply power to the brewer and refer to Testing Individual Components. If the full supply voltage is measured when the tank heater is turned on, and zero voltage is measured with the triac off, then the triac is good. If half the supply voltage is measured, the triac is defective. If very low, or zero voltage is measured, there could be a defective triac or a defective 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.

Spitting or unusual steaming from sprayhead or air vents. (Water too hot)

1. Triac

2. Lime Buildup

CAUTION - Tank and tank components should be delimed regularly depending on local water conditions. Excessive mineral buildup on stainless steel surfaces can initiate corrosive reactions resulting in serious leaks.

Inspect the tank assembly for excessive lime deposits. Delime as required.
