Brew and Dispense Sequence
Thebrewtankisinitiallylleduponstartupandmonitoredbytheowcountsfromtheow
meter.Oncethetankhasmetitsowcountnumber,thebrewtankwillbeginheating.Atthis
point, the incoming recipe brew water will displace the recipe hot water. Water in the brew
tank will maintain a certain level when commanded by the brew switch.
Once you depress the brew start button, a series of recipe brew events can take place dur-
ing the brew process depending upon how the selected coffee parameter menus are set.
Pre-wetting of the coffee grounds (ambient water), pre-infusion (percentage of overall brew
volume),llpause(delayafterpre-infusionbeforeremainingbrewwaterisintroducedand
brew turbulence intervals associated with the brew time menu setting).
The turbulence is the newest technology used to enhance the roll of the coffee grounds in
the brew chamber during the coffee extraction. Once all the recipe parameters have timed
out, the brewer will begin pressing out the coffee in the brew chamber using an air pump.
The air vent valve will close, shutting off the vent to the brew chamber and the press out
air pump will turn on for the amount of time set in the recipe parameter setting. The coffee
exits out through the center of the stream guide/check valve by pressure created within the
brewchamberthatpushesthecheckvalveopen.Thecoffeeowsoverthestreamguide
and into the receiving coffee cup.
Rinse Sequence
After a brew is complete, remove the receiving container from the drip tray and place an empty container onto the
driptrayunderthebrewchamber.Youwillpresstherinsebuttononthecontrolpanelidentiedbythewatersymbol
at the top. The purpose of the rinse before removing the brew chamber assembly is to rinse the brew chamber wall
of any remaining coffee grounds and into the brew cup.
The brew chamber is ready to be disengaged from the brew cup by lifting up on the top handle and rotating the
brew top upwards. Remove the brew cup from the cup support base and empty the coffee grounds from the cup.
Thoroughly rinse the brew cup and screen in preparation for the next brew process.
