This function allows the operator to view or to enter the actual flow rate coming out of
the dilution nozzle. This is not used to control the actual flow rate, but to tell the internal
processor how fast the water is flowing.
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.
This function allows the operator to track the total number of brew cycles completed, as
well as the number of batches brewed using each of the brew buttons. There are (up to)
three resettable counters, and one life counter that is not resettable.
This function allows the operator to enter the machine’s asset number. This can be use-
ful for tracking the usage or service of an individual machine within a group.
This function allows the operator to enter in the telephone number to call if service is
needed. The service number will be displayed anytime there is a fault message dis-
played.

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 (on the side to be calibrated for Dual Brewers).
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.
