CALIBRATE FLOW

This function allows the operator to enter the

each side of the brewer by dispensing both separately
for one minute. The volumes are then entered in
ounces per minute (OZ/M).

and with a minimum capacity of 60 ounces, be-
neath the funnel on the side of the brewer to be
calibrated.

ing ounces per minute.

display to match the amount in the container. Then
