CALIBRATE FLOW
This function allows the operator to enter the actual
flow rate of the sprayhead and the bypass (for each side
on DUAL brewers) by dispensing both separately for
one minute. The volumes are then entered in ounces
per minute (OZ/M).
Procedures to calibrate the sprayhead flow rate:
1. Place a container, accurately graduated in ounces,
and with a minimum capacity of 60 ounces, beneath
the funnel (on the side to be calibrated on DUAL
brewers) on the brewer.
2. Press and hold upper right hidden switch until the
display reads UNITS. Release switch. Continue
to press and release switch until display reads
CALIBRATE FLOW ?.
3. Press and release YES to advance to the SPRAY
HEAD CAL? function screen. (Pressing NO in the
CALIBRATE FLOW screen will advance to the next
function screen, BREW COUNTERS).
4. Press and release YES. The display should read
CONTAINER READY? If the container is under
the funnel, press YES. The display should read
CALIBRATE SPRAY .. PRESS BREW TO START.
5. Press and release the BREW switch (on the side
to be calibrated for DUAL brewers). The display
should read CALIBRATE SPRAY .. 60 SEC TO FIN-
ISH. The 60 second timer on the display will count
down to zero. When the counter reaches zero, the
display will change to ENTER OZ, along with a
number signifying ounces per minute.
6. Measure the amount of water in the container
and using the (-) or (+), adjust the amount on the
display to match the amount in the container. Then
press DONE.
7. The display should now read:
NEW SPRAY FLOW (SINGLE brewers)
NEW L or R SPRY FLOW (DUAL brewers), along
with the correct flow rate of the sprayhead in ounces
per minute. After about 5 seconds, the display will
return to the CALIBRATE FLOW screen.
8. Repeat steps 1 - 8 when calibrating the other side
on DUAL brewers.
9. To exit the CALIBRATE FLOW program, press NO
to advance to the next function screen, or press
and release the ON/OFF switch (either on DUAL
brewers) located on the front switch panel to exit
the CALIBRATE FLOW function and return to the
MAIN SCREEN.
