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.Place the heater switch at the rear of the brewer in the “OFF” (lower) position and connect the brewer to the power source.

4.Fill the tank with water as directed:

4A.Models CW-APS & CW-TS:

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 CWT-APS, CWTF-APS, CWT-TS, CWTF-TS, CWT-TSR & CWTF-TSR

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.

5.When the flow of water from the funnel stops, place the heater switch at the rear of the brewer in the “ON” (upper) 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 CW-APS & CW-TS:

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

6B.Models CWT-APS, CWTF-APS, CWT-TS, CWTF-TS, CWT-TSR & CWTF-TSR

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 “OFF” (lower) 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 CWA-PS & CW-TS:

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

8B.Models CWT-APS, CWTF-APS, CWT-TS, CWTF-TS, CWT-TSR & CWTF-TSR

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, remove the front panel, and adjust the brew timer as required. See Adjusting Brew Volumes. Replace the front 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 following pages.
