NOTE: Do not pull apart filter at the glued spots. Glue is designed to ease installation.

1. Turn off blower and remove cover from air cleaner cabinets.
   Slide filter frame assembly out from cabinet and place on floor with
   black pleat spacers up.


2. Carefully remove the black pleat spacers. Unbutton the latches on
   the side of the frame and swing open the two end panels. Unfasten two
   hinged flaps on the top of the frame that hold filter in place. Remove
   old filter media and discard. NOTE: Do not handle insulation along sides
   of frame.


3. Place new filter in frame, cardboard flaps up. Insert the
   cardboard filter flaps into the notched channels on each side of the
   frame. Make sure the filter is centered in the frame, and pinch closed
   the hinged flaps.


4. Insert the black pleat spacers, one pleat per slot, and slide
   over to the proper position. Snap into notches in side channels. Be
   careful not to tear filter near glue beads. NOTE: Glue beads are for
   easier installation. These time-saver filters were created to
   automatically separate the pleats to the proper width without the use of
   strings or holes in the filter.


5. Close end panels on frame and snap latches closed at each
   corner. Reinstall the filter media frame in the cabinet with the airflow
   arrow in the same direction as the arrow on the cabinet. Attach outer
   cover and turn blower on.
