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. Select the desired recipe on the grinder. It is not necessary to select a recipe on the brewer.

2. Insert a BUNN filter into the funnel.

3. Grind the proper amount of fresh coffee into the Smart Funnel using the Multi-BrewWISE DBC grinder with

Smart Funnel operation and level the grounds by gently shaking.

4. Slide the funnel into the funnel rails. The brewer will read the recipe ground through the chip in the funnel handle and will automatically select the correct recipe to brew. If the grounds are not obtained through a grinder compatible with a Smart Funnel, a recipe must be chosen on the brewer.

5. Place an empty server under the funnel.

6. Press the "ON/OFF/POWER" pad and release.

7. Press the "ON/OFF/LOWER" warmer pad and release.

8 Momentarily press and release the "BREW" pad. 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" is pressed: a) BREW TEMPERATURE TOO LOW - wait until heated or cancel BREW LOCKOUT option. (Page 13) b) FUNNEL NOT PRESENT (or using a standard brew funnel) - cancel FUNNEL LOCKOUT option. (Page 34) c) CHECK FUNNEL - remove funnel, empty previously brewed grounds and grind a new batch into the funnel.

d) SWITCH NOT ON - Press the "ON/OFF/LOWER" warmer pad to ON and release. (Page 36)

9. If none of the above messages are displayed, the display will read NOW BREWING.

10. Following the BREW will be a countdown of drip time DRIPPING which shows the time remaining for drip-out 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. The sprayhead holes must always remain open.

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.

PROGRAMMING THE BREWER (cont.)


There are three methods of programming the various brewing parameters of the Single Multi-

BrewWISE DBC with Smart Funnel brewer.

METHOD 1:

Using a Smart Funnel and a Single Multi-BrewWISE

DBC Grinder:

Certain coffee NAMES are stored in the Multi-

BrewWISE DBC 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'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,

DILUTION 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 Single Multi-

BrewWISE DBC 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 name of the coffee, BREW

VOLUMES, DILUTION PERCENTAGES, PULSE BREW

TIMES, PREINFUSION TIMES, and DRIP-OUT TIMES.

METHOD 3:

Not using a Smart Funnel and/or a Single Multi-

BrewWISE DBC Grinder:

This allows the operator to enter ONE set of brewing parameters in the event a Smart Funnel and/ or a Single Multi-BrewWISE DBC Grinder is not used with the Single Multi-BrewWISE DBC 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


TIMES, PREINFUSION TIMES and DRIP-OUT TIMES for all batch sizes.

SET NEW RECIPE - METHOD 1

Using a Smart Funnel and a Single Multi-BrewWISE

DBC Grinder:

This function allows the operator to set 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 MULTI-

BREWWISE DBC 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 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


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.

Using a RECIPE CARD to load coffee names and brew settings into the Single Multi-BrewWISE DBC with

Smart Funnel:

The Multi-BrewWISE DBC Grinder's memory contains certain coffee names. If the operator uses a coffee name that is not already stored in the grinder's memory, a RECIPE CARD can be obtained from the factory. The RECIPE CARD would include all the information needed to set up that particular coffee name.

The information from the RECIPE CARD is loaded into the grinder's memory, then into the brewer's memory by holding the recipe card up to the equipment's sensing coil. This information can include the coffee name, BREW VOLUMES, DILUTION PERCENTAGES,

PULSE BREW TIMES, PREINFUSION TIMES and DRIP-

OUT TIMES for that particular recipe NAME. These can all be loaded in seconds.

Contact Bunn-O-Matic Corporation for the availability of RECIPE CARDS.

If not using a Smart Funnel (with a sensor coil) and/ or a Single Multi-BrewWISE DBC Grinder, the brewer will function as a standard BUNN Single Multi-

BrewWISE DBC Brewer:

It is possible to operate the brewer without using a Smart Funnel and/or a 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

"BREW" 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, DILU-

TION PERCENTAGES, PULSE BREW TIMES,

PREINFUSION TIMES and DRIP-OUT TIMES. The brewer will perform in the same capacity as a standard

BUNN Single Multi-BrewWISE DBC 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.

•

•

•

Inspection, testing, and repair of electrical equipment should be performed only by qualified 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 permanent. 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 solenoids are energized for more than ten minutes without a supply of water.

The use of two wrenches is recommended whenever plumbing fittings 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 isolated.

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

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.

1. Refill valve


Check the sensitivity setting. Refer to the Refill function on page 31. 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.

Test the Refill valve. Refer to Testing

Individual Components on page 36.

When this condition occurs, the brewer will display OVERFLOW CUP
