PROGRAMMING THE BREWER (cont.)

SET PULSE BREW:

This function allows the operator to program the brewer to "pulse” the sprayhead flow on and off con- tinually during a brew cycle (start and stop the flow of water out of the sprayhead). This feature allows the ability to “fine-tune” the brewer for specific flavor profiles. Pulse brewing can be set up for any and all batches.

a)1st ON TIME - This time is the duration from when the BREW switch is pressed to when the desired water level in the funnel is reached. (Soaking the grounds)

b)OFF-TIME - This time is the duration from when the water in the funnel reaches the desired ON TIME level to when it drains out of the funnel to a desired lower level.

c)LAST ON-TIME- This time is the duration from when the water in the funnel drains down to the lower level to when it fills the funnel to a desired higher level. (Soaking the grounds).

These three times can be set two different ways. The first is accomplished by utilizing the EASY PULSE screen and following the subsequent steps under that function.
