PROGRAMMING THE BREWER (cont.)

PROGRAMMING FUNCTIONS - LEVEL 2 (cont.)

*REFILL Range: 0 to 155

This function allows the operator to adjust the sensitiv- ity of the refill circuit. This is mainly a troubleshooting feature. Water in different geographical locations can have different conductivities. By adjusting the sensitivity of the refill circuit, this will allow the brewer to operate under various water conditions.

Procedure to set the sensitivity threshold of the refill circuit:

NOTE: Make sure the water in the tank is touching the refill probe.

1.Press and hold the right hidden switch until the display reads SET LANGUAGE. Press and release the right hidden switch until the display reads REFILL and shows a number on both sides of the word.

2.To adjust the threshold setting, press (-)to decrease or (+) to increase the setting.

NOTE: Always make sure that the number on the right is larger than the number on the left when water is in contact with the refill probe in the tank.

3.When finished, select DONE. This saves the new setting and advances to the next function screen (L) SPRAY OZ/M. To exit programming and return to the MAIN SCREEN, press ENABLE BREW ON/ OFF switch.

* SPRAY OZ/M

This function allows the operator to view or enter the actual flow rate coming out of each sprayhead. This is NOT used to control the actual flow rate, but to tell the internal processor how fast the water is flowing.

Procedure to set the sprayhead flow rate:

1.Press and hold the right hidden switch until the display reads SET LANGUAGE. Press and release the right hidden switch until the display reads SPRY OZ/M. The number represents what the brewer thinks is the flow rate out of that sprayhead.

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.

3.Select DONE.

4.Repeat procedure for right side of Twins.

5.When finished, press and release DONE to advance to the next screen. To exit programming and return to the MAIN SCREEN, press ENABLE BREW ON/

OFF switch.

NOTE: If the flow rate is unknown, proceed to the CALIBRATE FLOW screen.

* BYPASS OZ/M (ICB & ICB Twins only)

This function allows the operator to view or enter the actual flow rate coming out of each bypass fitting. This is NOT used to control the actual flow rate, but to tell the internal processor how fast the water is flowing.

Procedure to adjust the bypass flow rate setting:

1.Press and hold the right hidden switch until the display reads SET LANGUAGE. Press and release the right hidden switch until the display reads BYPASS OZ/M. The number represents what the brewer thinks is the flow rate out of that bypass.

2.If the actual flow rate of the bypass is known but is different than the number on the display, use the (-)and (+) to enter the correct flow rate.

3.Select DONE.

4.Repeat procedure for right side of Twins.

5.When finished, press and release DONE to advance to the next screen. To exit programming and return to the MAIN SCREEN, press ENABLE BREW ON/ OFF switch.

NOTE: If the flow rate is unknown, proceed to the CALIBRATE FLOW screen.

* DILUTE OZ/M (ITB/ITCB only)

This function allows the operator to view or to enter the actual flow rate coming out of the dilution nozzle. This is NOT used to control the actual flow rate, but to tell the internal processor how fast the water is flowing.

Procedure to adjust the dilution flow rate setting:

1.Press and hold the right hidden switch until the display reads SET LANGUAGE. Press and release the right hidden switch until the display reads DILUTE OZ/M. The number represents what the brewer thinks is the flow rate out of the dilution nozzle.
