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 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 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 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 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 until switch is once again placed in the “SET” position.
COFFEE BREWING
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.(This switch must be in the "ON" position to start and complete a
brewing cycle.)
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.
7. Remove funnel cover. Funnel should not be removed from urn until drip out of coffee has been completed.
8. To empty funnel, invert it over a waste container to dispose of filter and grounds. An additional flange is
provided on the funnel to help make this step easier.
NOTE: Hot water may be drawn from the hot water faucet during a brew cycle. However, if a large amount of hot
water is drawn off (over 1 gallon) operator should wait to do so between brewing cycles.
