TU3Q-EZ ADJUSTMENTS & OPTIONAL SETTINGS

Adjusting Total Volume

BREW VOLUME SET-UP: Use the following steps when

setting up the brewer for the first time.
1. Place an empty funnel in the funnel rails and an empty

vessel of at least 4 gallons beneath the funnel.

2. Place the "ON/OFF" switch in the "ON", up-

per position.

3. Press and hold the brew start switch until

you hear the brew solenoid click on-and-
off three times (approximately 5 seconds).
Release the switch immediately. Failure to
release the switch within 2 seconds of the
third click causes the volume setting to be
aborted and the previous volume setting
will remain in memory

4. Allow the cycle to continue until the desired

amount of water is dispensed and then turn
"OFF" the brewer.

The brewer is now set to dispense this amount
of water for each subsequent brew cycle.

To 

increase

 the amount of water for each

cycle place an empty funnel in the funnel rails
and an empty vessel of at least 4 gallons be-
neath the funnel. Place the "ON/OFF" switch in
the "ON", upper position. Press and hold the
"START" switch until you hear the solenoid
click on-and-off three times (approximately 5
seconds), then release the "START" switch
immediately.  Failure to release the switch
within 2 seconds of the third click causes the
volume setting to be aborted and the previ-
ous volume setting will remain in memory.
Momentarily press and release the "START"
switch once for each 3.2 ounces (approximate)
of water to be added to the prior setting and
allow the cycle to finish.

To 

decrease

 the amount of water for each

cycle place an empty funnel in the funnel rails
and an empty decanter or graduated vessel
beneath the funnel. Place the "ON/OFF" switch
in the "ON", upper position. Momentarily press
and release the "START" switch once for each
3.2 ounces (approximate) of water to be re-
moved from the existing setting. Press and
hold the "START" switch until you hear the
solenoid click on-and-off three times (approxi-
mately 5 seconds), then release the "START"
switch immediately (failure to release the
switch within 2 seconds of the third click
causes the volume setting to be aborted and
the previous volume setting will remain in
memory) and allow the cycle to finish.
