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 dispenser under the funnel.

3.Remove the front or rear panel and turn the thermostat knob to the “OFF” position and connect the brewer to the power source.

4.Fill the tank with water as directed:

4A. Models S & SA:

Pour three pitchers of tap water into the screened area on top of the brewer. Allow approximately two minutes between pitchers for water to flow into the tank. While the third pitcher of water is entering the tank, the tank will fill to capacity and the excess will flow from the sprayhead, out of the funnel, and into the dispenser.

4B. Models ST, STA:

Connect the brewer to the power source, place the "ON/OFF" switch in the "ON" upper position, and momentarily press and release the start switch. Water will begin flowing into the tank. When water stops flowing into the tank, initiate a second and a third brew cycle. During the third brew cycle the tank will fill to its capacity and the excess will flow from the sprayhead, out of the funnel, and into the dispenser.

4C. Models STF & STFA

Brewers will fill automatically when lower ON/OFF switch is placed in the "ON" position and tank will fill to capacity.

5.When the flow of water from the funnel stops, turn the thermostat knob to the “ON” position and wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Some water will drip from the funnel during this time; this is due to expansion and should not occur thereafter.

6.Empty the dispenser and initiate another brew cycle as directed:

6A. Models S & SA:

Pour one pitcher of tap water into the screened area on top of the brewer.

6B. Models ST, STF, STA & STFA:

Place the "ON/OFF" switch in the "ON" upper position, and momentarily press and release the start switch.

7.Place the "ON/OFF" switch in the lower “OFF” position after water has stopped flowing from the funnel, and let the water in the tank reheat to the proper temperature.

8.Empty the dispenser and proceed as directed:

8A. Models S & SA:

The brewer is now ready for use in accordance with the coffee brewing instructions on the next page.

8B. Models ST, STF, STA & STFA:

Place the "ON/OFF" switch in the "ON" upper position, and momentarily press and release the start switch. Check the water volume in the dispenser after water has stopped flowing from the funnel. It should be 64 ounces.

9.If not, disconnect the brewer from the power source. On early models remove the access panel. Adjust the timer as required (see service section). Replace the panel, connect the brewer to the power source, and allow the water to reheat, start, and measure another brew cycle.

10.Repeat step 9 until 64 oz water volume is achieved.

11.The brewer is now ready for use in accordance with the coffee brewing instructions on the next page.
