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 support, funnel and funnel cover are in place.

1.  Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the “SET” posi-

tion on the circuit board.

 

To increase a batch size. Press and hold the START or BREW switch until you see three breaks in the water 

stream from the swing arm. Release the switch (Failure to release the switch within two seconds after the 

third break in the water stream 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 you see three breaks in the water stream from the swing arm. Release the switch. (Failure to 

release the switch within two seconds after the third break in the water stream 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 you see three breaks in the water stream 

from the swing arm, and then release the switch. (Failure to release the switch within two seconds after the 

third break in the water stream 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 remembers 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.

NOTE: HALF-BATCH AND FULL BATCH SETTINGS MUST EACH BE SET SEPARATELY.

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. 

1.  Brewing cycles may be started whenever water temperature is correct. This condition is indicated by the dial 

thermometer on front of the brewer. Whenever the pointer is in the green, brewer is ready for brewing.

2.  Insert Bunn

®

 filter in funnel and add desired amount of coffee.

3.  Level the bed of coffee and place funnel into the funnel support. Place funnel cover over the funnel and be 

sure the water swing spout is over the center of the funnel cover.

4.  Turn "ON/OFF" switch to the "ON" position.

5.  Push and release "START" switch to start the brew cycle.

6.  Water swing spout should not be moved as long as water is flowing into the funnel cover. When water stops 

flowing, it may then be moved for access to brewing funnel.
