8. When the desired temperature is attained, place the funnel support, funnel, and funnel cover on top of the coffee
reservoir. Center the discharge of the water swing spout over the opening in the top of the funnel cover.
9. Place the lighted ON/OFF switch in the "ON" position and momentarily press and release the start switch.
Water should flow from the swing spout into the funnel assembly.
10. Drain and measure the water from the reservoir when the flow of water from this initial cycle stops. If it is
three gallons, proceed to step 12. If it is more or less than three gallons, proceed to step 11.
11. Adjust the brew timer as required. See Adjusting Brew Volumes. Repeat steps 9 & 10.
12. The brewer is now properly adjusted to brew coffee.
Bunn-O-Matic recommends a bead of silicon sealant be placed around the base on the countertop
after the initial operation instructions are completed. B.O.M. #M2509.1001 sealant is available.
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.
