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.

BREW LOCKOUT: The inability to initiate a brew if the water temperature is less than the ready temperature

programmed into the brewer.

BYPASS: The process of diverting a portion of the brew water to the outside of the paper ﬁlter so that it does

not pass through the coffee grounds. This process is sometimes used to optimize the ﬂavor of the ﬁnished brew.

CHIP: A computer chip containing either recipes for speciﬁc coffee ﬂavors or advertising messages which are

read by the sensing coils on the brewer. One chip is embedded in each Smart Funnel handle to carry the coffee ﬂavor name and batch size ground from the grinder to the brewer.

DRIP TIME: The length of time from when the water spray over the grounds ends, to the time that no water drips

from the funnel tip.

FACTORY DEFAULTS: The factory preset brew settings that were installed into the brewer's memory. FIRST ON-TIME: During a pulse brew, this is the time set for the initial ﬂow of water over the grounds. FUNNEL DETECT: Sets the inability to initiate a brew cycle if the funnel is not properly inserted into the funnel

rails.

FUNNEL SENSING COIL: A sensor on the front hood of the brewer, which reads what name and batch size of

coffee was ground into the funnel and allows for the brewer to automatically set itself to what is read from the funnel handle.

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.

2. Press the
