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.

Water will flow into the tank and dispenser for three and one-half minutes. Empty the dispenser when this first cycle stops and press the START switch again. Empty the dispenser when the second cycle stops and press the START switch once more. 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.

8. Start, and measure another cycle.

9. Repeat steps 6-8 until the recommended total water volume is achieved.

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