Installing the Air Filter
The BAC is shipped with an air filter. The air filter prevents dust from entering the
chassis. If this air filter is not already installed in the chassis, use the installation
procedure below. Once it is installed, you should inspect and replace the air filter
at least once a year. A harsh environment will require more frequent filter changes.
To purchase a replacement air filter, contact your sales representative.
Procedure
To install the air filter:
1. Unfasten the screws on the vent cover and remove it.
2. The air filter mounts at an angle within the chassis. Slide the air filter upwards
into the air filter guides located on the inside of each side wall. Slide the filter
upwards until it seats against the foam strip located on the backplane.
NOTE:
When oriented properly, the vertical arrows on the front and rear edges of
the filter point up.
3. Replace the vent cover plate, ensuring that the plate’s foam strip presses
against the front of the filter.
4. Replace the screws.
