Installation, Operation, and Maintenance Instructions
This manual is the property of the owner, and is required for future maintenance. Please leave it with the
owner when the job is complete.
RECEIVING AND HANDLING
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).
SAFETY WARNING:
Improper installation, adjustment, alteration,
service or maintenance can cause property
damage, injury or death. Read the installation,
operating, and maintenance instructions
thoroughly before installing or servicing this
equipment.
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 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 or linkage. 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. (See Figure 1)
3) Do not install screws in damper frame that will interfere with damper blades and prevent them 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.
