INITIAL SET-UP (TB3/TB3-LP/TB6 ONLY)

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

1.Remove the top lid from the brewer.

2.Rotate the control thermostat knob fully counterclockwise to the "OFF" position and replace the top lid.

3.Set the delay dial on the timer at three minutes and set the dilution dial at three to four minutes.

4.Remove the metal discharge tip from the funnel to speed up the set-up procedure. Insert the empty funnel into the funnel rails. On TB6 models, rotate the funnel handle left or right to align the funnel to the reservoir.

5.Place an empty dispenser on the brewer base. Be sure the funnel discharge is directly above the hole in the dispenser top lid.

6.Plug in the brewer and place the ON/OFF switch in the "ON" position ("SWEET" or "UNSWEET" position for models with a sweetener option) (LEFT or RIGHT on TB6). Momentarily press the start switch. Water will flow into the tank. When the fill valve shuts off, place ON/OFF switch to "OFF" position, then back ON. Press the start switch again. During the second period, the tank will fill up and the excess will flow from the funnel into the dispenser.

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

8.Disconnect the brewer from the power source and remove the top lid.

9.Rotate the control thermostat knob fully clockwise to the "ON" position and replace the top lid.

10.Plug in the brewer and wait for the water in the tank to heat to the set temperature (approx. 20 minutes). Some water will drip from the funnel during this time; this is due to expansion and should not occur thereafter.

11.Place the ON/OFF switch in the "ON" position and press the start switch. Empty the dispenser after water has stopped flowing from the funnel.

12.Allow the water in the tank to reheat to the proper temperature.

13.Place the ON/OFF switch in the "ON" position (LEFT or RIGHT on TB6) and press the start switch.

14.Place the ON/OFF switch in the "OFF" position immediately after water stops flowing from the funnel. Check the water volume in the dispenser. It should be seventy-six ounces.

15.If not, adjust the digital timer as required. See Adjusting Brew Volumes, and measure another brew cycle.

16.Repeat steps 12-15 until the proper water volume is achieved. Empty the dispenser.

17.Place the ON/OFF switch in the "ON" position (LEFT or RIGHT on TB6), momentarily press the start switch, and allow both the concentrate and dilution cycles to finish.

18.When all water stops flowing, check the water volume in the dispenser. It should be 396 ounces.

19.If not, unplug the brewer and remove the top lid. Adjust the dilution dial on the timer as required.

20.Replace the top lid, plug in the brewer, start, and measure another brew cycle.

21.Repeat steps 17-20 until the proper water volume is achieved.

22.Return the delay dial on the timer to eight minutes. Replace the top lid and plug in the brewer.

23.Reinstall the metal discharge tip into the funnel.

24.Load the funnel with a BUNN® paper filter and approximately four ounces of loose tea leaves.

25.Place the ON/OFF switch in the "ON" position, momentarily press the start switch, and allow both the concen- trate and dilution cycles to occur. Observe the funnel discharge and the dilution streams near the end of the brew cycle. The dilution stream should stop approx. 30 seconds after the funnel discharge has stopped.

26.If not, unplug the brewer and remove the top lid.

27.Adjust the delay dial on the timer as required. Replace the top lid and plug in the brewer.

28.Repeat steps 24-27 until the proper dilution timing is achieved.
