3. Remove all wires from the timer.

4. Attach all wires to the replacement timer board

prior to installation to the component mounting

bracket. Refer to FIG. 5 when reconnecting the

wires.

5. Install new circuit board with spacers (as re-

quired) to the component mounting bracket.

6. Adjust the timer as described below.

Timer Setting:

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 pre-

vious 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 pre-

vious volume setting will remain in memory). Allow

the brew cycle to finish in order to verify that the de-

sired 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 set-

ting 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 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 pre-

vent any further programming until switch is once

again put into the “SET” position.
