Attach the double-sided filter rails horizontally to the face of the inlet hood using two #10-24 x ½" bolts and
#10-24 nuts on each side. When attaching the filter rails, insert the bolt from the inside of the filter rail to
allow for maximum clearance for the filters. Attach the snap fastener with one TEK self-tapping screw
each. (First remove the washer as the washer will restrict the snap fastener, making it difficult to open.)
NOTE: Inlet hood with birdscreen does not require filters or snap fasteners.
