OPERATION
Introducon to S Series Operaon
S Series machines are designed to operate as fully volumetric machines. This means that any me a group is
acvated, it will run the selected program unl the set volume has been dispensed. S Series machines do
not have a manual operaon mode.
S Series machines come with a single pump/motor. They are designed to operate with two stages of pres-
sure proling for brewing espresso. The shot begins with preinfusion. Low pressure water saturates the
puck, swelling it to reduce channeling. Aer the programmed preinfuse me has elapsed, the full pump
pressure (typically 9 bar) stage begins. This stage will connue unl the programmed volume of water has
been dispensed. The pump and brew group then shut o to end extracon, returning the machine to idle
pressure.
S Series machines come equipped with a handheld controller and LCD display to allow for adjustments of
the machine tank temperatures and brew parameters. Each brew group has two available programs which
can be easily accessed and adjusted through the controller.
Preparing to Brew Espresso
1. Select the desired spout and basket conguraon. Single, double and boomless portalters are availa-
ble through Synesso™. The single spout portalter is used with a single (7g) basket to brew a single shot.
The double spouted and boomless portalters can be used with double (14g) or triple (18g or 21g) bas-
kets to brew double or triple shots. The double spouted portalter can separate a double shot into 2 sin-
gle shots of espresso.
2. Fill the portalter basket with coee grounds to just above level and wipe o the excess.
Note: For best results, use fresh coee. Ground coee should be brewed as soon as possible aer grinding.
3. Press straight down evenly on top of the grounds with the tamper. (A tamper is supplied with the ma-
chine).
4. If desired, purge the group to heat the diuser before proceeding to the brewing process. S Series ma-
chines have purge buons, which will dispense a med pulse of full pressure water to aid in cleaning or
warming the group between shots. Set the duraon of the purge in the handheld controller.
