thoroughly dried before replacing it.

the fan access cover at the bottom front of the chassis.

3. Remove the filter from the access cover and clean it. If the filter
is washed, it should be thoroughly dried before replacing it.
3.7.2 Replacing the Chassis Filter

cover on the chassis.
2. Secure the fan access cover by tightening the captive
thumbscrew.
