Calibrating the Sprayhead Flow Rate

Step 1: Place a measuring container with a minimum capacity of 60 ounces
beneath the funnel of the brewer. Water can also be dispensed into the server and
then into the measuring container.
Step 2: Press and hold the right hidden switch to enter level 2 programming.
Continue to press the right hidden switch until the display reads "Calibrate Flow?".
Step 3: Press YES to advance to the "Spray Head Cal?" function screen.
Step 4: Press YES. The display will read "Container Ready?" If the container is
under the funnel, press YES. The display will read "Calibrate Spray...Press Brew to
Start".
Step 5: Press and release the BREW switch. The display will 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 OZ, along with the
existing ounces per minute.
Step 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.
Step 7: The display should now read "New Spray Flow" along with the correct flow
rate of the sprayhead in ounces per minute. After 5 seconds, the display will return
to the "Calibrate Flow?" screen.
