INITIAL SET-UP

CAUTION – The brewer must be unplugged throughout the initial set-up, except when specified in the instruc- tions.

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.Insert the funnel (empty) into the funnel rails.

4.Place an empty tea dispenser on the brewer base. Be prepared to empty the dispenser a few times.

5.Plug in the brewer, place the TEA/OFF/COFFEE switch in the “COFFEE” position, and momentarily press the start switch. When the flow of water into the tank stops, press the START switch to initiate a second cycle. Wait until the flow of water stops and start a third cycle. During the third cycle, the tank will fill to its capacity and the excess will flow from the funnel into the dispenser. Empty the dispenser when this third cycle stops.

6.Place the TEA/OFF/COFFEE switch in the “TEA” position and begin another brew cycle.

7.Measure the total water volume from the dispenser. It should be approximately (396 ounces.)

8.If not, adjust the Iced Tea Brew Timer (right timer) as required. (See Adjusting Brew Volume)

9.Start, and measure another cycle.

10.Repeat steps 7-9 until the recommended total water volume (396 ounces) is achieved.

11.The concentrate valve is pre-adjusted to deliver the correct ratio of brew water to dilution water.

12.Unplug the brewer, remove the top lid, rotate the control thermostat knob fully clockwise to the “ON” position and replace the top lid.

13.Empty the dispenser.

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

15.Place the TEA/OFF/COFFEE switch in the “COFFEE” position and begin another brew cycle. Empty the reser- voir after water has stopped flowing from the funnel.

16.Allow the water in the tank to heat to the proper temperature and begin another brew cycle.

17.Measure the total water volume from the dispenser. It should be approximately 64 ounces.

18.If not, adjust the Coffee Brew Timer (left timer) as required. (See Adjusting Brew Volume)

19.Start, and measure another cycle.

20.Repeat steps 17-19 until the recommended total water volume (64 ounces) is achieved.

21The brewer is now ready to brew approximately one-half gallon of hot coffee or 3-gallons of freshly brewed room temperature tea.
