SPRAY OZ/M (cont.)

Procedure to adjust the flow rate setting:

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

2.If the actual flow rate of the sprayhead 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 R SPRY OZ/M. When finished setting the right side, press and release DONE to advance to next function screen, L BYPS OZ/M. Another alternative is to press and release either ON/OFF switch located on the front switch panel to exit R SPRY 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.

Procedure to adjust the flow rate setting:

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

3.When finished, press and release the DONE. This saves the new setting and advances to R BYPS OZ/M. When finished setting right side, press and

release DONE to advance to next function screen, CALIBRATE FLOW. Another alternative is to press and release either ON/OFF switch located on the front switch panel to exit the BYPASS OZ/M func- tion 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 for each side of the brewer 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, be- neath the funnel on the side of the brewer to be calibrated.

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. The display should read CALIBRATE SPRAY .. 60 SEC TO FINISH. 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 L or R SPRY 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
