Upon receiving dampers, check for both obvious and hidden damage. If damage is found, record all
necessary information on the bill of lading and file 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 excess of 100°F (37ºC).
Due to continuing research, Greenheck reserves the right to change specifications without notice.
Pre-Installation Guidelines
The basic intent of a proper installation is to secure the AMS & AMD 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 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, pick-ups,
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.
