Timer Setting:
NOTE: Check that the brewer is connected to water
supply, the tank is properly filled, and a funnel and
server are in place, prior to setting or modifying
volumes.
NOTE: All volume settings must be done with the
sprayhead installed.
1. Modifying brew volumes. To modify a brew vol-
ume, first check that the SET/LOCK switch is in the
"SET" position on the circuit board.
To increase a brew volume, place the ON/OFF
switch in the "ON" position, press and hold the
START 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 brew volume, place the ON/OFF
switch in the "ON" position, press and release the
START switch once for every two-second interval
to be removed from the total brew time period;
then immediately press and hold down the START
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 brew volumes. To set a brew volume, first
check that the SET/LOCK switch is in the "SET"
position on the circuit board. Place the ON/OFF
switch in the "ON" position, press and hold the
START 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". NOTE: Several ounces of water will
continue to syphon from the tank after turning the
switch "OFF". 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, volumes will de-
crease due to absorption by the coffee grounds.
3. Setting programming disable feature. If it be-
comes necessary to prevent anyone from chang-
ing brew time once programmed, you can set the
SET/LOCK switch to the "LOCK" position. This will
prevent any further programming.
