Press the “continuous” button to allow water to enter
into the coffee boiler and wait for the brewing phase to end.
Repeat twice. Now it is necessary to remove all of the air in the
coffee boiler to saturate the group. This is commonly referred
to as bleeding the group. To do this, remove the group cover
by rotating the cover counter clockwise (AV models) or remove
the pressure gauge, remove the paddle knob, remove the cover,
replace the pressure gauge and rotate the lever to the left (MP
models).

Unscrew the bleed screw
(approximately 1/2 turn) to release all
air from the coffee boiler (using the
8
included 5mm hex key wrench). When water
leaks from under the screw head, tighten the
screw. Note: It might be necessary to activate
the brewing process to force water into the
boiler. To do this, press the continuous
key until water leaks from under the screw
head. Then tighten screw. Replace group
cover removed in previous step. The steam
boiler will begin to ll automatically and
the reservoir will need to be relled. Once
boiler is full, heating phase will begin and
the expansion valve will need to be adjusted
immediately (see next step).
