PROGRAMMING FUNCTIONS - LEVEL 2 (cont.)
CALIBRATE FLOW
This function allows the operator to enter the
actual flow rate of the sprayhead and the bypass for
each side of the brewer 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, be-
neath the funnel on the side of the brewer to be
calibrated.
2. Press and hold the ® pad until the display reads
SET NEW RECIPES. Release the ® pad. Press and
release the ® pad until the display reads CALI-
BRATE 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 the YES pad. The display should
read CONTAINER READY? If the container is un-
der the funnel, press YES. The display should read
CALIBRATE SPRAY .. PRESS BREW TO START.
5. Press and release the pad on the side to be
calibrated. 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 signify-
ing ounces per minute.
6. Measure the amount of water in the container and
using the (-) or (+) pads, adjust the amount on the
display to match the amount in the container. Then
press DONE.
7. The display should now read NEW L or R SPRY
FLOW, 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. To exit the CALIBRATE FLOW program, press NO
to advance to the next function screen, or press
and release the pad located on the front
switch panel to exit the CALIBRATE FLOW func-
tion and return to the MAIN SCREEN.
9. Repeat steps 1 - 8 when calibrating the other side.
