4.1 REMOVAL OF SHOWER,
PAVILION AND SEAL
To remove the shower and pavilion it is suf-
ficient to loosen the central screw under the
group.
To change the seal use an awl or a slim flat-
head screwdriver and at first remove one
edge of the seal and then remove it entirely.
If the group is worn out just insert shims
under the seal so as to reduce the stroke of
the filter holder.
4.2 FILTER HOLDER
PRESENCE SENSOR
The filter holder presence sensor (A) informs
the control unit about the presence, or not,
of the filter holder in the infusion group.
In this way it permits the auto-purge fea-
ture.
It is visible in the back of the group head
and comes out in the inner of the group
head.
NOTE
When the filter holder sensor is func-
tioning, an orange light means the
presence of the filter holder, while no
light means its absence.
