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.

4.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. 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 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 next page.

ADJUSTING BREW VOLUMES

CAUTION - Disconnect the power source from the brewer prior to the removal of any panel for the replacement or adjustment of any component.

NOTE: Prior to setting or modifying batch sizes, check that the brewer is connected to water supply, the tank is properly filled, and a funnel and server are in place.

1.Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the “SET” position on the circuit board.

To increase a batch size. Press and hold the START or BREW switch until three clicks are heard. Release the switch (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory) and press it again one or more times. Each time the switch is pressed, two seconds are added to the brew time period. Allow the brew cycle to finish in order to verify that the desired volume has been achieved.

To decrease a batch size. Press and release the START or BREW switch once for every two-second interval to be removed from the total brew time period; then immediately press and hold down the START or BREW switch until three clicks are heard. Release the switch. (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). Allow the brew cycle to finish in order to verify that the desired volume has been achieved.
