A. On/Off Brew Station Warmer Switch
Placing the switch in the upper position supplies power
to the brew station warmer and enables brewing. Plac-
ing the switch in the lower position cuts power to the
brew station warmer and stops brewing. Stopping a
brew cycle after it has been started will not stop the
flow of water into the funnel until the tank syphons
down to its proper level.
NOTE - The On/Off brew station warmer switch must
be in the upper position to initiate and complete a brew
cycle.
B. On/Off Brew Station Warmer Indicator Lamp
Glows whenever the On/Off brew station warmer
switch is in the upper position showing that the
warmer is on and that the automatic brew cycle can
be started.
C. Start Switch
Starts a brew cycle when the On/Off brew station
warmer switch is in the upper position.
D. Upper Warmer Switch
Placing the switch in the upper position supplies power
to the upper warmer. Placing the switch in the lower
position cuts power to the upper warmer.
E. Upper Warmer Indicator Lamp
Glows whenever the upper warmer switch is in the

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.
