Section 7: Inspection and maintenance
Ensure that the plenum and duct have no loose or missing hard-
ware. If any self-tapping screws are stripped out install a 1/4 in.-20
nut with locking hardware on the backside of the screw and torque
per
. Periodically inspect the air filter on the duct, if present,
and replace if soiled or clogged.
Section 8: Renewal parts
When ordering renewal or spare parts, include as much information
as possible. In many cases, the style number of the new part can
be obtained from identification on the old part. Always include a
description of the part. Specify the rating, structure number, and
shop order number, located on the nameplate of each section.
