Installation, Operation, and Maintenance Instructions
Pre-Installation Guidelines
The basic intent of a proper installation is to secure
the AMD-xx-TD series 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 your schedule for proper damper locations
within the building. Visually inspect the damper
for damage.
2. When you lift or handle the damper use the sleeve
or frame. Do not lift damper using blades, linkage,
actuators, probes, or jackshafting. When you
handle multiple section 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
interfere with unexposed blade linkage and prevent
damper blades from opening and/or closing.
