* CALIBRATE FLOW
This function allows the operator to test and enter the
actual flow rate of the sprayhead(s) and the bypass/
dilution for each side of the brewer by dispensing each
separately for one minute. The volumes are then entered
into the brewer.
Procedure to calibrate the sprayhead flow rate:
1. Place a container, accurately graduated with a mini-
mum capacity of 60 ounces, under the funnel.
2. Press and hold the right hidden switch until the
display reads SET LANGUAGE. Press and release
the right hidden switch until the display reads
CALIBRATE FLOW?
3. Select YES to advance to SPRAY HEAD CAL screen.
(Selecting NO in the CALIBRATE FLOW screen will
advance to BREW COUNTERS).
4. Select YES.
The display should read CONTAINER READY? If

5. The display should read CALIBRATE SPRAY. Press
and release any BREW button on the side to be cali-

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 LEFT or RIGHT OZ,
along with a number.
6. Measure the amount of water in the container and
use (-) and (+) to match the display to the amount
in the container. Then select DONE.
7. The display should now read NEW L or NEW R
SPRY FLOW, along with the correct flow rate of
the sprayhead. After about 5 seconds, the display
will return to the CALIBRATE FLOW screen.

using the (-) and (+), adjust the amount on the
display to match the amount in the container. Then
