PULSE BREW SETUP PROCEDURE (CDBC TWIN & CDBCF TWIN)

The pulse brew parameters (initial fill time, off times, and remaining on times) are entered using the following set- by-example process.

1.First set the brew volume using the standard procedure in Brew Volume Setup.

2.Position an empty container under the sprayhead. Allow the tank to finish refilling. Make sure that the READY lamp is on, or that the BREW LOCKOUT function is turned off.

3.Press and hold the OFF/ON button. The brew valve will turn on after 10 seconds. Release the button. This begins the initial on-timesetting. When the spray has continued for the desired time, momentarily press the OFF/ON button.

4.The spray is now stopped and the off time setting has begun. Press the OFF/ON button momentarily to end the off time.

5.The spray is now on again and the remaining on time setting has begun. Press the OFF/ON button momentarily at the end of the desired remaining on time.

6.The setup is now complete and the parameters are stored in memory. The spray will continue the off and on cycles until the brew volume of step 1 is complete. Pressing the OFF/ON button again will terminate the brewing cycle, with the parameters stored in memory.

7.If only a preinfusion is desired, i.e. an initial on time followed by one off period, use the same procedure, but stop after step 4 and allow the brew to finish the volume set in step 1. This will store the initial on time and off time in memory.

Procedure for Disabling Pulse Brew or Preinfusion:

1.Position an empty container under the sprayhead. Allow the tank to finish refilling. Make sure that the READY lamp is on, or that the BREW LOCKOUT function is turned off.

2.Press and hold the OFF/ON button. The brew valve will turn on after 10 seconds. Release the button.

3.Allow the spray to continue and press no buttons until spray stops. The pulse and preinfusion functions are now disabled.

NOTE: When the brewer has been set up for pulse or preinfusion, the adjustment of brew volume is done the same as always and has no effect on the pulse brew parameters. The pulsing is temporarily disabled while adjusting the brew volume and automatically returns during normal brewing.
