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 20 mins for the water in the tank to heat to the proper temperature on 120V/208V ma-

chines. (Wait approximately 45 mins on 120V machines). 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 (indicator lit). 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 BREW switch

is pressed:

a) ENABLE BREW must be ON. b) BREW TEMPERATURE TOO LOW - wait until heated or cancel BREW LOCKOUT option. c) FUNNEL NOT IN PLACE (or using a standard brew funnel) - cancel FUNNEL DETECT. d) CHECK FUNNEL - remove funnel, empty previously brewed grounds and grind a new batch into the fun-

nel.

7. If none of the above messages are displayed, the display will read NOW BREWING and the time remaining

in the brew cycle.

8. Following the BREW will be a countdown 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. Do NOT clean this equipment with a water jet device.

2. Check and clean each sprayhead. The sprayhead holes must always remain open.

NOTE: Any buildup on the sprayhead and ﬁtting may restrict water ﬂow, and impact your coffee brewing. For

consistently great coffee, clean sprayhead and ﬁttings weekly with sprayhead cleaning tool (#38227.0000). Upon visual inspection it may appear that light passes through all holes in the sprayhead plate, but a thin ﬁlm of residue can pass light and still impede water ﬂow.

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.

5. Remove sprayhead from brewer. Disassemble by removing the seal.

6. Use the pointed end of sprayhead cleaning tool to remove any mineral deposits from the sprayhead holes.

7. Reassemble sprayhead and reattach. Sprayhead only needs to be hand tightened.

See page 34 of instruction manual for calibration routine to verify sprayhead ﬂow rate matches programmed

ﬂow rate. Machine may need to be re-calibrated due to lime build up. If machine is cleaned and build up

removed, machine must be re-calibrated to achieve desired volumes.

PROGRAM FUNCTIONS - LEVEL 2

There are three methods of programming the various brewing parameters of the Single TF 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. 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 ﬂavor. 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 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 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 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 grinder'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 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 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 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 hid-

den switch until the display reads UNITS. Release the switch, then press and release the switch again until the display reads SET NEW RECIPIE.

4. Press and release YES. The display should read

INSERT FUNNEL WITH NEW NAME, then QUIT SETUP? These three 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 BREW OZ. SETTING OR ADJUSTING for description).

SET NEW RECIPE: If not using a Smart Funnel (with a sensor coil) and/or a G9-2T DBC or MHG Grinder, the brewer will function as a standard Bunn Single TF DBC 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 name when the BREW switch is pressed. This means that no name was read from the funnel's handle. There is one NO NAME coffee program that can be set in the brewer. It is referred to as NO NAME. 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, 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 ThermoFresh Server beneath the brew funnel.

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.

Possible Cause

3. Reﬁll Probe or Sensitivity Setting

Troubleshooting Procedure

Check the sensitivity setting. Refer to the 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.

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. 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 vent. (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.

Possible Cause

3. Electronic control board

1. Strainer

2. Improper water pressure

3. Brew Valve

Troubleshooting Procedures

Perform the previous 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 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. 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

If bypass is being used on the inconsistent brewing recipe, test the Bypass Valve. Refer to Testing Individual Components. 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.
