a claim with the final carrier. Check to be sure that
all parts of the shipment, including accessories, are
accounted for.
Dampers must be kept dry and clean. Indoor storage
and protection from dirt, dust and the weather is
highly recommended. Do not store at temperatures in

Pre-Installation Guidelines
The basic intent of a proper installation is to secure the
backdraft damper into the opening in such a manner
as to prevent distortion and disruption of damper
operation. The following items will aid in completing the
damper installation in a timely and effective manner.
1) Check the schedules for proper damper locations
within the building. Visually inspect the damper for
damage.
2) Lift or handle damper using sleeve or frame. Do
not lift damper using blades, linkage, actuators,
or jackshafting. When handling multiple sections
assemblies, use sufficient support to evenly lift at
each section mullion (see drawing). Do not drag, step
on, apply excessive bending, twisting, or racking.
3) Do not install screws in damper frame that will
