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 .
4 . Damper must be installed into duct or opening
square and free of twist or other misalignment .
Damper must not be squeezed or stretched into
duct or opening . Out of square, racked, twisted
or misaligned installations can cause excessive
leakage and/or torque requirements to exceed
damper/actuator design .
5 . Damper, actuator, and transmitter must be kept
clean, dry and protected from dirt, dust and other
foreign materials prior to and after installation .
Examples of such foreign materials include but are
not limited to:
a) Mortar dust
b) Drywall dust
c) Firesafing materials
d) Wall texture
e) Paint overspray
Spreader Bar
Attachments
Multi section dampers
6 . Damper should be sufficiently covered as to prevent
overspray if wall texturing or spray painting will
be performed within 5 feet (1 .5m) of the damper .
Excessive dirt or foreign material deposits on the
damper can cause excessive leakage and/or torque
requirements and inaccurate airflow measurement to
exceed damper/actuator design .
7 . ACCESS: Suitable access (actuators maintenance,
etc .) must be provided for damper inspection
and servicing . Where it is not possible to achieve
sufficient size access, it will be necessary to install a
removable section of duct .
Electrical Guidelines
All wiring shall be done in accordance with the National
Electrical Code ANSI/NFPA-70 latest edition, any local
codes that may apply, and wiring diagrams developed
in compliance with the job or project design and
specifications .
Important!
Electrical in put may be needed for this equipment . This
work should be performed by a qualified electrician .
Verify power before wiring actuator . Greenheck is not
responsible for any damage to, or failure of the unit
caused by incorrect field wiring . To avoid causing death
or serious bodily harm to building occupants, follow all
instructions carefully . Dampers must close completely to
preserve the integrity of the fire smoke separation .
Connect electrical connection to power strip as shown
in drawings on pages 4 and 5 .
