* CALIBRATE FLOW

This function allows the operator to test and enter the actual flow rate of the sprayhead(s) and the bypass/ dilution for each side of the brewer by dispensing each separately for one minute. The volumes are then entered into the brewer.

Procedure to calibrate the sprayhead flow rate:

1.Place a container, accurately graduated with a mini- mum capacity of 60 ounces, under the funnel.

2.Press and hold the right hidden switch until the display reads SET LANGUAGE. Press and release the right hidden switch until the display reads

CALIBRATE FLOW?

3.Select YES to advance to SPRAY HEAD CAL screen. (Selecting NO in the CALIBRATE FLOW screen will advance to BREW COUNTERS).

4.Select YES.

The display should read CONTAINER READY? If container is under the funnel, select YES.

When the counter reaches zero, the display will change to LEFT or RIGHT OZ, along with a number.

6.Measure the amount of water in the container and use (-)and (+) to match the display to the amount in the container. Then select DONE.

7.The display should now read NEW L or NEW R SPRY FLOW, along with the correct flow rate of the sprayhead. After about 5 seconds, the display will return to the CALIBRATE FLOW screen.

8.Repeat steps 1-7 to calibrate the other side.

9.To exit the CALIBRATE FLOW function and advance to the next screen, select NO. To exit programming and return to the MAIN SCREEN, press either EN- ABLE BREW ON/OFF switch.

1.Place a container, accurately graduated with a mini- mum capacity of 60 ounces, under the funnel.

2.Press and hold the right hidden switch until the display reads SET LANGUAGE. Press and release the right hidden switch until the display reads

CALIBRATE FLOW?

3.Select YES to advance to SPRAY HEAD CAL screen. Select NO to advance to BYPASS CAL.

4.Select YES.

The display should read CONTAINER READY? If container is under the funnel, select YES.

5.The display should read CALIBRATE BYPASS. Press any BREW button on the side to be calibrated to begin the flow for calibration. The display should read CALIBRATE BYPASS...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 LEFT or RIGHT OZ/M, along with a number.

6.Measure the amount of water in the container and using the (-)and (+), adjust the amount on the display to match the amount in the container. Then select DONE.

7.The display should now read NEW L or NEW R BYPS FLOW, along with the correct flow rate of the bypass. After about 5 seconds, the display will return to the CALIBRATE FLOW screen.

8.Repeat steps 1-7 to calibrate the other side.

9.To exit the CALIBRATE FLOW function and advance to the next function screen, select NO. To exit pro- gramming and return to the MAIN SCREEN, press ENABLE BREW ON/OFF switch.

Procedure to calibrate the dilution flow rate: (ITCB)
