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 1⁄2" or larger supply line. A shut-off valve 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 is 1⁄4" flare or female quick connect. NOTE – Bunn-O-Matic recommends 1⁄4" copper tubing for installations of less than 25 feet and 3⁄8" for more than 25 feet from the 1⁄2" 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-Matic does 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. Attach the flare fitting from the short piece of tubing on the strainer/flow control (supplied) to the water inlet

fitting on the back of the brewer.

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

3. Turn on the water supply.

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.) PROGRAMMING FUNCTIONS - LEVEL 2

There are three methods of programming the various brewing parameters of the Single MultiBrewWISE 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 MultiBrewWISE 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 MultiBrewWISE 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

VOLUMES, DILUTION PERCENTAGES, PULSE BREW TIMES, PREINFUSION TIMES and DRIP-OUT TIMES

for all batch sizes.
