ELECTRICAL REQUIREMENTS

CAUTION - The brewer must be disconnected from the power source until specified in

120V model brewers require 2-wire, grounded service rated 120 volts ac, 15 amp, single phase, 60 Hz.

Proceed as follows:

Electrical Hook-Up

CAUTION – Improper electrical installation will damage electronic components.

1. An electrician must provide electrical service as specified.

2. Using a voltmeter, check the voltage at the electrical source.

3. Connect the brewer to the power source.

4. If plumbing is to be hooked up later be sure the brewer is disconnected from the power source. If plumbing

has been hooked up, the brewer is ready for

Initial Set-Up

Initial Set-Up.

PLUMBING REQUIREMENTS

These brewers must be connected to a cold water system with operating pressure between 20 (138) and 90 psi (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.

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 countertop. 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).

2. Attach the flare fitting from the short piece of tubing on the strainer/flow control (supplied) to the water inlet fitting at the rear of the brewer.

3. Flush the water line and securely attach it to the flare fitting on the strainer/flow control.

4. Turn on the water supply.

INITIAL SET-UP

CAUTION - The brewer must be disconnected from the power source throughout the initial set-up, except when

specified in the instructions.

1. Insert an empty funnel into the funnel rails.

2. Place an empty container of at least 4 gal. capacity under the funnel.

3. Connect the brewer to the power source.

4. Place the "ON/OFF" switch in the "ON" position and momentarily press the "START" switch.

5. Water will flow into the tank and dispenser for approximately three and one-half minutes. Empty the dispenser when the first cycle stops and press the "START" switch again. Empty the dispenser when the second cycle stops and press the "START" switch once more. During the third cycle, the tank will fill to its capacity and the excess will flow from the brew funnel into the dispenser. Empty the dispenser when this third cycle stops.

6. Wait approximately twenty minutes for the water in the tank to heat to the proper temperature.

7. Place the "ON/OFF" switch in the "ON" position then momentarily press and release the "START" switch.

8. Allow the cycle to finish and measure the amount of water in the container. It should be 396 ounces ± 2. Refer

OPERATING CONTROLS

A. ON/OFF Switch

ON - Placing the switch in the left position allows the start switch to activate a timed brew cycle for three gallons

of tea.

OFF - Placing the switch in the right position stops the brew cycle. Stopping a brew cycle after it has been started will not stop the flow of water into the funnel until the tank syphons down to its proper level. The switch should

always be placed in this position after a brew cycle and whenever the brewer is unattended.

B. Start Switch Starts a brew cycle when the ON/OFF switch is in the "ON" position.

C. Ready Indicator This indicator glows when preselected brew water temperature has been achieved. It is also used for diagnostic testing of brewer.

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. Place the ON/OFF switch in the "OFF" position. 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.

3. Insert the deliming spring into the sprayhead fitting until no more than two inches is visible and move it in and out 5 or 6 times. Reattach the sprayhead.

4. Wash the entire outside surface of the brewer with a clean damp cloth.

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

TEA BREWING

1. Begin each brew cycle with a clean empty brew funnel and server. (Be sure the server lid doesn’t interfere with the flow of dilution water.)

2. Insert a BUNN® filter into the funnel.

3. Pour the packet of loose fresh tea leaves into the filter. Approximately four ounces is recommended.

4. Level the bed of tea leaves by gently shaking.

5. Slide the funnel into the funnel rails until it stops.

6. Place the ON/OFF switch in the "ON" position.

7. Momentarily press the start switch.

CAUTION - The funnel contains hot liquids. Remove funnel slowly.

8. Carefully remove the brew funnel and discard the used filter when tea no longer drips from the funnel tip.

9. Place the ON/OFF switch in the "OFF" position to prevent a false start.

10. Fresh tea is available at the faucet.

TU3Q-EZ ADJUSTMENTS & OPTIONAL SETTINGS

P1864

P1901

Adjusting Total Volume

BREW VOLUME SET-UP: Use the following steps when

setting up the brewer for the first time.

1. Place an empty funnel in the funnel rails and an empty vessel of at least 4 gallons beneath the funnel.

Page 7

2. Place the "ON/OFF" switch in the "ON", upper position.

3. Press and hold the brew start switch until you hear the brew solenoid click on-andoff three times (approximately 5 seconds). Release the switch immediately. Failure to release the switch within 2 seconds of the third click causes the volume setting to be aborted and the previous volume setting will remain in memory

4. Allow the cycle to continue until the desired amount of water is dispensed and then turn "OFF" the brewer.

The brewer is now set to dispense this amount of water for each subsequent brew cycle.

To increase the amount of water for each

cycle place an empty funnel in the funnel rails and an empty vessel of at least 4 gallons beneath the funnel. Place the "ON/OFF" switch in the "ON", upper position. Press and hold the "START" switch until you hear the solenoid click on-and-off three times (approximately 5 seconds), then release the "START" switch immediately. Failure to release the switch within 2 seconds of the third click causes the volume setting to be aborted and the previous volume setting will remain in memory. Momentarily press and release the "START" switch once for each 3.2 ounces (approximate) of water to be added to the prior setting and allow the cycle to finish.

To decrease the amount of water for each

cycle place an empty funnel in the funnel rails and an empty decanter or graduated vessel beneath the funnel. Place the "ON/OFF" switch in the "ON", upper position. Momentarily press and release the "START" switch once for each

3.2 ounces (approximate) of water to be re-

moved from the existing setting. Press and hold the "START" switch until you hear the solenoid click on-and-off three times (approximately 5 seconds), then release the "START" switch immediately (failure to release the switch within 2 seconds of the third click causes the volume setting to be aborted and the previous volume setting will remain in memory) and allow the cycle to finish.
