Basic position/filling
The brew cylinder is somewhat
underneath the middle of the complete
lifting area. The lower piston is at the
lower end of the brewing cylinder. This
makes the maximum cylinder volume
available for filling with ground coffee.
The ground coffee is filled by the grinder
over the inlet and into the funnel.
Brewing
The brewing cylinder and piston are at
the upper end of the lifting range when
the funnel is swung away. The outlet
piston closes the brewing cylinder on
top and the ground coffee is pressed on
it. The brewing water is pressed from
underneath in the brewing cylinder and
the coffee runs up through the outlet
piston and the angle piece to the spout.
Both positions, “open brewing cylinder”
and “post-pressing” are differentiated
only slightly from this position. When
“Open brewing cylinder” is selected, the
brewing cylinder is move downward by
afew millimeters after pressing and
pre-steeping the ground coffee. With
post-pressing, after the brewing process
the brewing cylinder is moved slightly
upward and held in this position for
ashort period of time in order to press
out the remaining water in the coffee
grounds through the supply pipe and
through the release valve.
