1.3.1 Changing the Air Filter (Racksystem)
The rack systems are equipped with an air filter which must be changed
when dirty. Note the following steps while replacing the air filter:
The protective cover has to be locked completely (snapped in place on the
right side).
The fan cover can be lifted off (there is no need to remove the cover of the
system unit); it is simply snapped in place.
The air filter is not attached to anything and can easily be removed.
