Bunn IC3B warranty Adjusting Brew Volumes, Initial SET-UP

INITIAL SET-UP (cont.)

Water will flow into the tank and dispenser for five minutes and forty-five seconds. 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.

6.Disconnect the brewer from the power source, remove the rear trunk panel, and turn the handle on the needle valve approximately one-quarter turn counterclockwise to enable the flow of dilution water. This valve is fully

closed at the factory.

NOTE - The next step requires the use of a stopwatch to calculate the amount of dilution water flowing from the nozzle in one minute. You’ll need to capture and measure the timed dilution water in a separate vessel than the one used for the water flowing from the funnel.

7.Place a vessel under the brew funnel to catch the brew water. Use a hose or other means to divert the water from the dilution nozzle to a separate container.

8.Connect the brewer to the power source. Simultaneously press the start switch to begin another brew cycle and start the stop watch. Place the ON/OFF switch in the “OFF” position at exactly sixty-seconds (one- minute). When the flow of water stops, measure the volume of the captured dilution water. It should be approximately twenty-two ounces.

9.If not, disconnect the brewer from the power source, and adjust the handle on the needle valve clockwise to decrease the amount of water or counterclockwise to increase the amount of dilution water as required.

10.Repeat steps 8 & 9 until the recommended dilution water volume (twenty-two ounces) is achieved.

11.Disconnect the brewer from the power source and reinstall the rear trunk panel.

12.Unplug the brewer, remove the top lid, rotate the control thermostat knob fully clockwise to the "ON" position and replace the top lid.

13.Empty the dispenser.

14.Connect the brewer to the power source and wait for the ready light to glow indicating the water in the tank has heated to brewing temperature (approximately 20 minutes). Some water will drip from the funnel during this time; this is due to expansion and should not occur thereafter.

15.Begin another brew cycle and measure the total water volume from the dispenser. It should be approximately 3 gallons and 12 ounces. (396 ounces).

16.If not adjust the timer as required. See Adjusting Brew Volumes.

17.Start, and measure another cycle.

18.Repeat steps 16-17 until the recommended total water volume is achieved.

19.The brewer is now ready to brew a batch of freshly brewed room temperature coffee.

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
