PROGRAMMING THE BREWER (cont.)

SPRAY OZ/M (cont.)

SPRAY OZ/M: XXX (-) DONE (+)

P2721

Procedure to adjust the flow rate setting:

1.Press and hold the upper right hidden switch until the display reads UNITS. Release the switch, then press and release switch until the display reads SPRAY OZ/M. The number represents what the brewer thinks is the flow rate of the sprayhead valve in ounces per minute.

2.If the actual flow rate of the sprayhead valve is known, but is different than the number on the display, use the (-)and (+) to enter the correct flow rate in ounces per minute.

3.When finished, press and release DONE. This saves the new setting and advances to the next function screen, BYPASS OZ/M. Another alternative is to press the ON/OFF switch located on the switch panel to exit SPRAY OZ/M function and return to the MAIN SCREEN.

BYPASS OZ/M

This function allows the operator to view or to enter the actual flow rate coming out of the bypass nozzle. This is NOT used to change the actual flow rate, but to tell the internal controller how fast the water is flowing. The unit of measure is ounces per minute.

BYPAS OZ/M: XXX (-) DONE (+)

P2721

Procedure to adjust the flow rate setting:

1.Press and hold the upper right hidden switch until the display reads UNITS. Release the switch, then press and release switch until the display reads BYPAS 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 (+) to enter the correct flow rate in ounces per minute.

3.When finished, press and release DONE. This saves the new setting and advances to the next function screen, CALIBRATE FLOW. Another alternative is to press the ON/OFF switch located on the front switch panel to exit the BYPASS OZ/M function and return to the MAIN SCREEN.

CALIBRATE FLOW

This function allows the operator to enter the actual flow rate of the sprayhead and the bypass by dispens- ing 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 brewer.

2.Press and hold the upper right hidden switch until the display reads UNITS. Release the switch, then press and release switch until the 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 the YES pad. 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. 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 measured in 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, 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.To exit the CALIBRATE FLOW program, press NO to advance to the next function screen, or press the ON/OFF switch located on the front switch panel to exit the CALIBRATE FLOW function and return to the MAIN SCREEN.
