Operating instructions

PROGRAMMING PROCEDURES (continued)
Pre-infusion is used to pre-wet
the bed of grounds or tea leaves
prior to the actual brew. This may
be used to improve the brew
quality in certain situatons.
Pulsing the delivery of brew water
extends the time the water is in
contact with the coffee grounds or
tea leaves. This can be adjusted
to optimize extraction rates.
Pulsing the delivery of brew water
all ows more tim e for the water to
drip out of the brew chamber.
This can be set to prevent brew
chamber overflow when very fine
grind coffee is used.
Bypass System delivers a portion
of the total volume of water
directly to the container. This is
used in situations where delivery
of all water through the coffee
grounds or tea leaves would
result in too strong a product.
PULSE BREW PRE-INFUSION CAPABILITY
BYPASS SYSTEM
Applications:
1. Pre-infuse (or Pre-soak) the Bed of Coffee or Tea.
The brew valve can be opened for a -short period of time to
allow the bed of coffee or tea to be pre-infused. After a delay
while the pre-soaking is taking place, the brew valve can be
opened to start and complete the brew.
2. Extend Contact Time With the Coffee.
The brew valve can be programmed to "pulse" by opening
and closing for programmed periods during the brew. This
capability will allow for longer contact with the coffee or tea if
higher extraction rates are required.
3. Prevent Brew Chamber Overflow.
The pulse feature allows the delivery time of the water to be
extended. Overflow problems can also be experienced if
particularly fine grind coffee is used. The SS2 can be
programmed to extend the delivery of the water over a longer
period of time, thus preventing any overflow problems.
Access the Pulse System:
1. Select the Brew Volume that will be using the "pulse" brew
system. (i.e. Brew Volume 1, 2, 3 etc.)
2. With the selected volume on the screen (e.g.: BrewVoI1:),
change volume if necessary (must not be "0") and press the
4th key (while in total valve time display) to go to the Pulse
Programming options (as opposed to pressing the 3rd key
which would bypass Pulse Programming).
3. The first three menu items below will appear in this order.
a. InitVlv Time: Initial Valve Time (seconds) to open before
pulse cycle(s) begin.
b. Pulse Delay: Number of seconds valve is closed
beginning pulse cycle(s).
c. Pulse Valve On: Number of second's valve is open
during pulse cycle(s).
d. Total Valve: Total number of seconds valve is to be open
(pulse + initial). This determines your total volume out of
brew chamber, which must be set if total volume changes
from factory settings.
e. Drip Out Time: Time after valve is closed before all water
drips through brew chamber as brewed product and the
brew is complete.
