4. Attach all wires to the replacement timer board
prior to installation to the component mounting
bracket. Refer to FIG. 22 when reconnecting the
wires.
5. Install new circuit board with spacers (as required)
to the component mounting bracket.
6. Adjust the timer as described below.
Timer Setting (Digital):
NOTE: Prior to setting or modifying volumes, check
that the brewer is connected to water supply, the
tank is properly filled, and a funnel and server are in
place.
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
and press it again one or more times. (Failure to re-
lease the switch within two seconds after the third click
causes the volume setting to be aborted and previous
volume setting will remain in memory) 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 im-
mediately 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). Al-
low 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. Models Single CW only, place the
selector switch in the half 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
approximately 50 ounces is reached, turn the ON/OFF
switch to “OFF”.
NOTE: Several ounces of water will continue to sy-
phon 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, volume will decrease
due to absorption by the coffee grounds.
3. Setting programming disable feature. If it be-
comes necessary to prevent anyone from changing
brew time once programmed, you can set the SET/
LOCK switch to the “LOCK” position. This will prevent
any further programming until switch is once again
put into the “SET” position.
