5.3 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 direction of
airflow for technical reasons (space, specific compo-
nent air routing etc.), this is easily achieved.
◾ Unlock the bayonet connection and detach the fan
housing from the filter box.
This is done in the same way as described in
section5.2 "Rotating the voltage connection",
page8.
◾ Turn the fan housing by 180°.
