Bunn TNTF-3 service manual INITIAL SET-UP cont, Adjusting Brew Volumes

INITIAL SET-UP (cont.)

13.Empty the dispenser.

14.Plug in the brewer and wait for the water in the tank to heat 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.Place the ICED/OFF/HOT switch in the “HOT” position and begin another brew cycle. Empty the reservoir after water has stopped flowing from the funnel.

16.Allow the water in the tank to heat to the proper temperature and begin another brew cycle.

17.Measure the total water volume from the dispenser. It should be approximately 64 ounces.

18.If not, adjust the Hot Tea timer as required. See Adjusting Brew Volumes.

19.Start and measure another cycle.

20.Repeat steps 17-19 until the recommended total water volume (64 ounces) is achieved.

21The brewer is now ready to brew approximately one-half gallon of hot tea or 3-gallons of freshly brewed room temperature tea.

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.

2.Setting batch sizes. To set a batch volume, first check that the SET/LOCK switch is in the “SET” position on the circuit board. Press and hold the START or BREW switch until three distinct clicks are heard, and then 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). View the level of the liquid being

dispensed. When the desired level is reached, turn the ON/OFF switch to “OFF” (lower). The brewer remem- bers this volume and will continue to brew batches of this size until the volume setting procedure is repeated.

NOTE: When brewing coffee, batch volumes will decrease due to absorption by the coffee grounds.

3.Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew times once programmed, you can set the SET/LOCK switch to the “LOCK” position. This will prevent any program- ming to be done until switch is once again placed in the “SET” position.
