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.

PROGRAM FUNCTIONS - LEVEL 2

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.

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 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 PERCENT-

AGES, PULSE BREW TIMES, PREINFUSION TIMES,

and DRIP-OUT TIMES.

METHOD 3:

Not using a Smart Funnel and/or a G92T DBC Grinder:

This allows the operator to enter ONE set of brew- ing 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.

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 NAME can be set individually to provide optimum

brewing quality.

Procedure for Setting the Recipe: NOTE: Before beginning setup, place a server beneath

the sprayhead.

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.

ing, remove the funnel.

3. On the brewer, press and hold the ® pad until the display reads SET NEW RECIPE. Release the ® pad.

4. Press and release YES. The display should read

INSERT FUNNEL WITH NEW NAME, then QUIT SETUP? These two displays will repeatedly

cycle.

5. Insert the funnel into the rails 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 page 19 for description of BREW OZ. function).

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

the

pad is pressed. This means that no name was

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

Single

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.

SET PULSE BREW:

This function allows the operator to program the brewer to "pulse” the sprayhead ﬂow on and off 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 pad 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 by observing the ﬂow of water for on and off times. This is accomplished by utilizing the SET BY EXAMPLE 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.

Modifying pulse brew: Range: 1st on time - off to 4 minutes Off time - off to 4 minutes Last on time - off to 4 minutes

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.

3. Reﬁll Probe or Sensitivity Setting

Troubleshooting Procedure

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.

Water ﬂows into tank continuously

with power removed from brewer.

3. Triac

4. Electronic Control Board

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 on page 33. 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.

3. Electronic control board

1. Strainer/ﬂow control (.750 GPM)

2. Improper water pressure

3. Brew Valve

Troubleshooting Procedures

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.

(A) Direction of ﬂow arrow must be pointing towards the brewer.

(B) Remove the strainer/ﬂow control and check for obstructions. Clear or replace.

Check operating water pressure to the brewer. It must be between 20 and 90 psi (138 and 620 kPa).

Test the Brew Valve. Refer to Testing Individual Components on page 33. Turn the valve on for 30 seconds and collect the water dispensed from the sprayhead. Repeat the test several times to conﬁrm a consistent volume of dispensed water. If not consistent, check the valve, tubing and sprayhead for lime buildup.

4. Bypass Valve

5. Lime buildup

Page 44

If bypass is being used on the inconsistent brewing recipe, test the Bypass Valve. Refer to Testing Individual Components on page 33. Turn the valve on for 30 seconds and collect the water collected from the bypass opening. Repeat the test several times to conﬁrm a consistent volume of dispensed water. If not consistent, check the valve, tubing and bypass opening for lime buildup.

Inspect for lime buildup that could block the tank, tank ﬁttings, tubing, valves and sprayhead.
