CALIBRATE FLOW
This function allows the operator to enter the actual
fl ow 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 fl ow 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 upper right hidden switch until the
display reads UNITS. Release switch. Continue
to press and release switch until display reads

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 L or R SPRY
