PROGRAMMING THE BREWER (cont.)

SET PREINFUSION:

This function sets the brewer to turn the sprayhead flow on for a preset time (1st ON TIME) followed by a preset spray pause (OFF TIMES) and then turn the spray on continuously until the brew volume is completed.

This is a special case of pulse brew. It is not pos- sible to set a batch size to have both pulse brew and preinfusion. One or the other (or neither) must be chosen. However, it is possible to set one batch size to pulse brew and the other two to preinfusion or vice versa.
