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.
