Bunn TU3Q service manual Auto Sweetener SET-UP, Adjusting Brew Volumes

AUTO SWEETENER SET-UP (cont.)

product for at least 4 minutes without shutting off. Some pump systems shut off after a few minutes of continu- ous running.

4.Plug brewer into the power source.

5.Place an empty reservoir under the dilution nozzle of the brewer.

6.Close the adjustment valve on the rear of the brewer fully (clockwise), then open (counterclockwise) 1/2 turn.

7.Set the selector switch to the "Sweetened" side and press the "Start" switch momentarily. (The sweetener will come out immediately.)

8.Run sweetener for 1 minute, then set selector switch to the "Off" position. The flow will stop.

9.Measure the amount of sweetener dispensed and calculate if the volume needs to be increased or decreased (Dilution cycle is usually between 3 to 3 1/2 minutes).

10.If adjustment is needed, turning the adjustment valve clockwise decreases the amount of sweetener dis- pensed and turning the adjustment valve counterclockwise increases the amount of sweetener dispensed.

11.After the desired volume has been set, turn the water supply on.

12.Reinstall the top lid, lower and upper rear panels.

The brewer may now be returned to service.

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 ÒSETÓ 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 ÒSETÓ 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 (UNSWEET/OFF/SWEET) switch to ÒOFFÓ .

The brewer remembers this volume and will continue to brew batches of this size until the volume setting procedure is repeated.

NOTE: When brewing tea, batch volumes will decrease due to absorption by the tea leaves.

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 ÒLOCKÓ position. This will prevent any program- ming to be done until switch is once again placed in the ÒSETÓ position.
