Installation Procedure

shelf and slowly slide the FTM until the it is flush with the chassis.
2. Tighten the four chassis retention screws to secure the FTM. The recommended
torque settings is 3.5 inch-pounds.

6.7 Replacing the Fan Filter
Your replacement fan filter consists of a filter media for the fan bezel, and a smaller media for
the inlet region adjacent to the SAMs.
Air filters should be checked occasionally to make sure they are not obstructed or damaged.
Visually inspect filters for tears or rips. Do not reinstall a torn filter as it will be ineffective in
trapping particulates and will interrupt air flow distribution. To maintain safety certification,
use only Emerson approved fan filters. You can order replacement fan filters (part number
RAF640) by contacting your Emerson sales representative. For detailed information on filter
maintenance and cleaning, see
Air Filter Maintenance on page 84 .
Replacement Procedure
To replace the fan filter, follow these steps. Please have your replacement fan filter available
before starting this procedure.
Main Filter Replacement Procedure
1. Remove the front bezel by squeezing the retention clasps incorporated into the top
corners of the bezel and rotating the top of the bezel away from the chassis.
2. Place the bezel face down so that the filter media and metal frame are facing up,
and rotate the filter frame away from the housing.
3. Insert the replacement fan filter on the bezel by aligning the oval cutouts in the
filter material with the light-pipe ovals.
