Fig. 8.3: change the filter inserts
To clean or change the filter inserts, carry out the following steps (see fig.
8.4):
1
Loosen the four screws and remove the housing lid.
2
Remove the filter inserts and check how soiled they are. The inserts
can be cleaned if there is a small amount of soiling and must be re-
placed if soiling is heavy.
3
Carefully clean the inside of the housing from any dust. Replace the
cleaned or replaced filter inserts in the correct sequence, which is
shown on the instruction label of the housing floor.
4
Replace and screw down the housing lid.
In environments with a high level of fine-grade dust, three optional fine
dust filters can be used in addition.
Opening the housing lid of the air filter LF-AD-x causes an air flow fault
in TITANUS
