PROGRAMMING THE BREWER (cont.)

SET TEMP (cont,)

SET TEMP: XXX° (-) DONE (+)

P2721

Procedure to set brew temperature:

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

SET TEMP.

2.To adjust the brew temperature, press (-)to de- crease or (+) to increase the brew temperature.

3.When finished, press and release DONE to save the new setting, exit the SET TEMP function and advance to the next function screen, SET READY. Another alternative is to press the ON/OFF switch located on the front switch panel to exit the SET TEMP function and return to the MAIN SCREEN.

SET READY - Range: 185˚F (85˚C) to 203˚F (95˚C) This function allows the operator to set the mini- mum temperature allowable to start a brew cycle. The range can be from 185˚F (85˚C) to within 2˚F (-1.7°C) of the SET TEMP. The water must be at the SET READY temperature or higher for the display to indicate READY TO BREW. If brew lockout is enabled, the brewing pro-

cess will not start below this READY temperature.

NOTE: The upper limit is the water temperature control setting minus 2˚F (-1.7°C).

SET READY: XXX° (-) DONE (+)

P2721

Procedure to set ready temperature:

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

SET READY.

2.To adjust the ready temperature, press the (-)switch to decrease, or (+) to increase the ready temperature.

3.When finished, press and release DONE to save the new setting, exit the SET READY function and ad- vance to the next function screen, REFILL. Another alternative is to press the ON/OFF switch located on the front switch panel to exit the SET READY function and return to the MAIN SCREEN.

REFILL - Range: 20 to 230

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

XXXREFILL -> XXX (-) DONE (+)

P2721

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 upper right hidden switch until the display reads UNITS. Release the switch, then press and release switch until the display reads REFILL and shows a number on both sides of the word.

2.To adjust the threshold setting, press (-)to de- crease, 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, press and release DONE. This saves the new setting and advances to the next function screen, SPRAY OZ/M. Another alternative is to press the ON/OFF switch located on the front switch panel to exit REFILL and return to the MAIN

SCREEN.

SPRAY OZ/M

This function allows the operator to view or to enter the actual flow rate coming out of the sprayhead. 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. (Oz/M)
