Changing the direction of airflow
The direction of airflow blows into the enclosure from
the outside as standard.
Should it become necessary to change the direc-
tion of airflow for technical reasons (space, specific
component air routing etc.), this is easily achieved.
Simply release the fan housing and rotate it through
180°. To release, please follow the same procedure
as described under section 5.2 "Rotating the voltage
connection", page 7.
Please also observe the instructions outlined under
section 4.2.1 "General", page 5.

Installing and changing the filter
The fan-and-filter unit and outlet filter are supplied as
standard with a standard fleece filter mat for the pre-fil-
tering of dry coarse dust and lint in the ambient air.
To increase the protection category and for presence of
dust with a grain size <10 μm, we recommend the use
of pleated filters (see section 13 "Accessories").
The filter should be checked at regular intervals in
accordance with the level of dust exposure (recom-
mended: at the latest after 2,000 operating hours) and
replaced as necessary.

Note:
Use only original Rittal filters which bear the
Rittal logo in order to safeguard the desig-
nated protection category, air throughout
and operating approvals.
The fleece filter mat supplied for the fan-
and-filter unit must be removed and dis-
posed of when a pleated filter is used.
Risk of injury!
Only change the filter mat while the fan
rotor is stationary.
Never insert your fingers into the fan
rotor.
To insert or replace the filter, proceed as follows (direc-
tion of airflow: drawing from outside and blowing into
the enclosure).

Replacing the fleece filter
◾ First press the catch of the louvred grill (Rittal logo)
up slightly with one finger (see fig. 6).
◾ Once it is released, the louvred grille can be dropped
open by approx. 70° or 90°.
◾ Remove the dirty fleece filter mat and place the new
fleece filter mat in the filter housing.
◾ When installing, ensure that the roughened side with
the Rittal logo points inside.
◾ Now push the louvred grille back onto the enclosure
until it snaps audibly into position.

Note:
If it becomes necessary to change the direc-
tion of the airflow (see section 5.3 "Chang-
ing the direction of airflow", page 8), the
installation is reversed accordingly.
