4. Lay the track ducts on the rail ties alongside where they will be installed.
5.
Refer to the drawing 92774. Place the track duct support brackets in position on
the ties so that one is near the heel end and one near each joint. Use the lag bolts
to fasten the brackets in place. Lay the track duct on the bracket bases. Place the
hold-down straps over the track ducts. Attach the hold-down strap to the track
duct support brackets by inserting the spring clip into the strap.
6.
Push in the square knockouts in the track ducts where airflow is desired. The
knockout should be pushed in and bent completely so that no portion of the
knockout obstructs the airflow in the duct. Knockout tabs that are not bent back
completely will obstruct the airflow as it moves through the track duct resulting in
reduced air pressure and airflow further along the track duct.
