INITIAL SET-UP

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

1.Insert an empty funnel into the funnel rails.

2.Place an empty decanter under the funnel.

3.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.

4.When the flow of water from the funnel stops, connect the brewer to the power source and turn on the power switch (back of brewer) 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. Empty the decanter.

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

6.After water has stopped flowing from the funnel, allow the water in the tank to completely reheat.

7.Empty the decanter. The brewer is now ready for use in accordance with the coffee brewing instructions.
