The pressure gauges are graduated in [Pa]
and contain green, yellow and orange sec-
tors. The filter cassette is to be replaced
when its pressure gauge has reached the
orange sector. The yellow sector is a war-
ning that the filter cassette replacement is to
be planned. For a service contact, see the
heading “Technical Support”.
If the filter stage is used with the pressure
drop within the orange sector, the filter unit
gives a reduced air volume.
Note however, that the filter unit will not be
damaged when operated with a clogged
filter stage, but the required air flow will not
be attained. Handling during service is de
-
scribed under “Changing the filter”.

1)
In order to get to know your new installation, the filter cassettes should be checked once a month during the first six months the
filter unit is in use. The service interval is then adapted according to the installation in question. However, no longer than six months
between inspections. Note that when the yellow LED lights, the inspection interval must be increased as the pressure drop now in-
creases quicklier.
2)
In order to get to know your new installation, the bottom section and drainage should be checked once a month during the first six
months the filter unit is in use. The service interval is then adapted according to the installation in question.
