material and workmanship existing at the time of manufacture and appearing within one year from the date of installation.
In addition:

1.) Bunn warrants electronic circuit and/or control boards to be commercially free from defects in material and work-

This warranty does not apply to any equipment, component or part that was not manufactured by Bunn or that, in
Bunn’s judgement, has been affected by misuse, neglect, alteration, improper installation or operation, improper mainte­nance or repair, damage or casualty.

THE FOREGOING WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ANY OTHER WARRANTY, WRITTEN OR ORAL,
EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF EITHER MERCHANTABILITY

period and no charge for labor by a Bunn Authorized Service Representative during the warranty period. If Bunn determines
that repair is not feasible, Bunn shall, at its sole option, replace the equipment or refund the purchase price for the equip­ment.

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

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).

4. Turn on the water supply.

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.
