H5
Vacuum chamber
overfilled
Maximum filling level
[03] in the vacuum
chamber exceeded.
Possible foaming in the
vacuum chamber.
Reduce the vacuum
pressure in the vacuum
chamber, e.g. from 300
mbar (absolute) to 400
mbar (absolute), and
increase the heating
temperature to reduce the
thickness of the oil film in
the vacuum chamber.
Note: If the vacuum
pressure cannot be
reduced any further,
replace the air filter.
H6
Entry blocked
No fluid is being sucked
into the FAM
Check shut-off device in
