This function allows the operator to test and enter the actual flow
rate of the sprayhead(s) for each side of the brewer by dispensing
each separately for one minute. The volumes are then entered into
the brewer.
WARNING: The sprayhead(s) must be installed before proceeding!
Procedure to calibrate the sprayhead flow rate:
1. Place a container, accurately graduated with a minimum capacity
of 60 ounces, under the funnel.
2. Press and hold the right hidden switch until the display reads
"AXIOM - VERSION #.#". Press and release the right hidden switch
until the display reads "CALIBRATE FLOW ?"
3. Select "YES". The display should read "CONTAINER READY?" If
container is under the funnel, select "YES".
4. The display should read "CALIBRATE SPRAY". Press and release
the "BREW" switch to begin the sprayhead flow for calibration. The
(+)
display should read "CALIBRATE SPRAY...60 SEC TO FINISH. The
60-second timer on the display will count down to zero. When
the counter reaches zero, the display will change to "ENTER OZ
25.0"
5. Measure the amount of water in the container and use (-) and (+)
to adjust the display to the amount in the container. Then select
"DONE"
6. The display should now read "NEW SPRAY FLOW" along with the
correct flow rate of the sprayhead. After about 5 seconds, the
display will return to the "CALIBRATE FLOW" screen.
7. To exit the "CALIBRATE FLOW" function and advance to the next
screen, select NO. To exit programming and return to the MAIN
SCREEN, press "ENABLE BREW ON/OFF" switch.
