CALIBRATE FLOW

This function allows the operator to enter the actual flow rate of the sprayhead and the bypass (for each side on DUAL brewers) by dispensing both separately for one minute. The volumes are then entered in ounces per minute (OZ/M).

Procedures to calibrate the sprayhead flow rate:

1.Place a container, accurately graduated in ounces, and with a minimum capacity of 60 ounces, beneath the funnel (on the side to be calibrated on DUAL brewers) on the brewer.

2.Press and hold upper right hidden switch until the display reads UNITS. Release switch. Continue to press and release switch until display reads

CALIBRATE FLOW ?.

3.Press and release YES to advance to the SPRAY HEAD CAL? function screen. (Pressing NO in the CALIBRATE FLOW screen will advance to the next function screen, BREW COUNTERS).

4.Press and release YES. The display should read CONTAINER READY? If the container is under the funnel, press YES. The display should read

CALIBRATE SPRAY .. PRESS BREW TO START.

5.Press and release the BREW switch (on the side to be calibrated for DUAL brewers). The display should read CALIBRATE SPRAY .. 60 SEC TO FIN- ISH. The 60 second timer on the display will count down to zero. When the counter reaches zero, the display will change to 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 SPRAY FLOW (SINGLE brewers)

NEW L or R SPRY FLOW (DUAL brewers), along with the correct flow rate of the sprayhead in ounces per minute. After about 5 seconds, the display will return to the CALIBRATE FLOW screen.

8.Repeat steps 1 - 8 when calibrating the other side on DUAL brewers.
