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" (12.7 mm) 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" (6.35 mm) ﬂare.

NOTE - Bunn-O-Matic recommends 1⁄4" (6.35 mm) copper tubing for installations of less than 25 feet (7.62 m) and

⁄8" (9.5 mm) for more than 25 feet (7.62 m) from the 1⁄2" (12.7) 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). For models installed outside the

U.S.A., you must comply with the applicable Plumbing/Sanitation Code for your area.

PLUMBING HOOK UP

1. Flush the water line and securely attach it to the inlet ﬁtting at the bottom rear of the brewer.

2. Turn on the water supply.

TANK DRAIN

1. Remove back access cover.

2. Close the white clamp on the drain hose.

Unfasten the hose clamp at the inlet valve. Remove the hose from the valve.

4. Place the end of the drain hose in a container that has a minimum capacity of 2.0 gallons (7.5 liters).

5. Release the white clamp to drain the water from the tank.

When tank is empty, leave the white clamp open, and install the hose back on the valve. Tighten the hose

clamp at the end of the hose around the valve ﬁtting.

CLEANING

CAUTION – CLEAN AND SANITIZE YOUR ICED TEA BREWER DAILY

1. Remove and thoroughly clean the entire brew funnel. The funnel tip and screen must be free from any tea

particles or residue. Reassemble the funnel.

2. Remove and thoroughly rinse the sprayhead. The holes must be open and clear of any mineral deposits. Wipe

the sprayhead panel clean with a damp cloth.

NOTE – Any buildup on the sprayhead may restrict water ﬂow, and impact yuor brewing. For consistently great tea and coffee, clean sprayhead weekly with sprayhead cleaning tool (#38227.0000). Upon visual inspection it may appear that light passes through all holes in the sprayhead, but a thin ﬁlm of residue can pass light and still impede water ﬂow. a. Remove sprayhead from brewer. b. Use the pointed end of sprayhead cleaning tool to remove any mineral deposits from the sprayhead

holes.

c. Insert the long end of sprayhead cleaning tool into the sprayhead ﬁtting, and rotate several times to

remove any mineral deposits from the ﬁtting.

3. 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.

CAUTION – DO NOT KEEP BREWED ICED TEA OVERNIGHT. THE SERVER MUST BE CLEANED DAILY.

See page 50 of instruction manual for calibration routine to verify sprayhead ﬂow rate matches programmed

ﬂow rate. Brewer may need to be re-calibrated due to lime build up. If brewer is cleaned and build up removed, brewer must be re-calibrated to achieve desired volumes.

Using a Smart Funnel and a G9-2T DBC or MHG Grinder: This function allows the operator to set BREW VOLUMES, 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 SENSING 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 VOLUME, PULSE BREW TIMES and DRIP OUT TIME for that particular coffee name. It also allows the operator to set other brewing parameters, such as BREW TEMPERATURE, BREW LOCKOUT, etc. Each coffee name can be set individually to provide optimum brewing quality.

SET NEW RECIPE Using a RECIPE CARD to load coffee names and brew settings

The G9-2T DBC or MHG 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 chip area up to the equipment’s SENSING COIL. This information can include the coffee name, BREW VOLUMES, PULSE BREW TIMES and DRIP OUT TIME for that particular coffee name. These can all be loaded in seconds.

2. Position the RECIPE CARD vertically, so that the top end of the CHIP is beneath the SENSING COIL (located on the middle of the underneath side of the front display panel).

3. After a short pause the display will read

CARD CONTAINS RECIPE FOR then will change to (COFFEE NAME) SHOW QUIT SAVE. All brewing parameters

for that coffee ﬂavor are now transferred from the CARD to the brewer.

Contact Bunn-O-Matic Corporation for the availability of RECIPE CARDS. NOTE: Instructions to program the brewer and grinder are printed on the RECIPE CARD, along with the coffee name that is being programmed.

Procedure to program the coffee name:

1. Remove the funnel (if present) from the funnel rails.
