HOW TO CALIBRATE SPRAYHEAD FLOW RATE
This function allows the operator to test and enter the actual flow rate of water coming out of the sprayhead(s).
The procedure includes a 1-minute dispense of water to determine the actual flow rate. Ensure that the brewer
is heated to brewing temperature before performing a sprayhead calibration.
1. Place a container, accurately graduated with a minimum capacity of 60 ounces, under the funnel.
