Procedure to adjust the flow rate setting:
1. Press and hold the ® pad until the display reads
SET NEW RECIPES. Release the ®. Press and
release the ® pad until the display reads BYPASS
OZ/M. The number represents what the brewer
thinks is the flow rate of the bypass valve in ounces
per minute.
2. If the actual flow rate of the bypass valve is known,
but is different than the number on the display, use
the (-) and (+) pads to enter the correct flow rate
in ounces per minute.
3. When finished, press and release the DONE pad.
This saves the new setting and advances to the
next function screen, CALIBRATE FLOW. Another
alternative is to press and release either of the
pads located on the front switch panel to exit the
BYPASS OZ/M function and return to the MAIN
SCREEN.

tell the internal controller how fast the water is flowing.
The unit of measure is ounces per minute.

REFILL - Range: 20 to 230
This function allows the operator to adjust the
sensitivity of the refill circuit. This is mainly a trouble-
shooting feature. Water in different geographical loca-
tions can have different conductivities. By adjusting
the sensitivity of the refill circuit, this will allow the
brewer to operate under various water conditions.
