INTRODUCTION

The 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 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.

PLUMBING REQUIREMENTS

This brewer must be connected to a cold water system with operating pressure between 20 and 90 psi (138 and 620 kPa) from a 12" or larger supply line. Ashut-offvalve should be installed in the line before the brewer. Install a regulator in the line when pressure is greater than 90 psi (620 kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is38" flare or female quick connect.

NOTE – Bunn-O-Maticrecommends38" copper tubing for all installations from the12" water supply line. A tight coil of copper tubing in the water line will facilitate moving the brewer to clean the counter top.Bunn-O-Maticdoes not recommend the use of a saddle valve to install the brewer. The size and shape of the hole made in the supply line by this type of device may restrict water flow.

This equipment must be installed to comply with the Basic Plumbing Code of the Building Officials and Code Administrators International, Inc. (BOCA)

and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).

PLUMBING HOOK-UP

1.Flush the water line and securely attach it to the flare fitting located on bottom of brewer.

2.Turn on the water supply.

OPERATING CONTROLS

(a) BATCH SELECTOR SWITCHES

Pressing the switch corresponding to the Small, Medium, or Large batch selects the amount of coffee to be brewed. Pressing a different switch after a brew cycle has been initiated does not change the brew batch in progress. Light indicates the selected batch to brew.

(b) ON/OFF SWITCH

Pressing the ON/OFF switch alternately turns the brewing side on and off. Pressing this switch during the brew cycle will interrupt the brew cycle, stopping the flow of water. Pressing this switch during the programming of the brewer will exit the setup and return to the main screen.

(c) BREW SWITCH

Momentarily pressing and releasing this switch begins a brew cycle.

(d) ® SWITCH

Pressing and holding the ® switch allows entry to the programming menus. Pressing and releasing the switch steps through each function screen during programming.

(e) FUNCTION SCREEN

This is the display which shows the various functions of the brewer and allows the programming to be accomplished.

(f) FUNCTION SCREEN SWITCHES

These are the hidden switches which are used to program the brewer.

(g) FUNNEL SENSING COILS

These are used to "receive" information from the Smart Funnel handle (coffee name and batch size), and also from RECIPE CARDS.

(h) SCROLL BACKWARDS

The upper left corner of the B in BUNN can be used to scroll backwards through the function list.

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 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 G9-2TDBC 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.

6The ON/OFF 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 brew switch is pressed:

a)ON/OFF must be ON.

b)BREW TEMPERATURE TOO LOW - wait until heated or cancel BREW LOCKOUToption.

c)FUNNEL NOT IN PLACE (or using a standard brew funnel) - cancelFUNNEL 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. 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-Maticequipment. DoNOT 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 sprayheads 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 fittings, and rotate several times to remove any mineral deposits from the fitting.

4.Insert the short end of sprayhead cleaning tool into the bypass fittings, and rotate several times to remove any mineral deposits from the fitting.

5.Remove sprayheads 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 sprayheads and reattach. Sprayheads only needs to be hand tightened.

See page 35 of instruction manual for calibration routine to verify sprayhead flow rate matches programmed flow rate. Machine may need to be re-calibrateddue to lime build up. If machine is cleaned and build up removed, machine must bere-calibratedto achieve desired volumes.
