PROGRAMMING FUNCTIONS (cont.)
SET PULSE BREW
This function allows the operator to program
the brewer to "pulse" the sprayhead fl ow on and off
during a brew cycle (start and stop the fl ow of water
out of the sprayhead). This feature allows the ability
to "fi ne-tune" the brewer for specifi c fl avor profi les.
Pulse brewing can be set up for any and all batches.

a) 1st ON TIME - This time is the duration from
when the pad 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 fi lls the funnel to a desired higher
level. (Soaking the grounds).
These three times can be set two different ways.
The fi rst is by observing the fl ow of water for on and
off times. This is accomplished by utilizing the SET BY
EXAMPLE screen and following the subsequent steps
under that function.
The other allows the actual times to be entered
for each of the settings. This is done by utilizing the
ENTER TIMES screen and following the subsequent
steps under that function.
Either of these methods can be used to set the
pulse brew for each batch.
