Greenheck RBD & RBDR Series (473325) - Manual

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 (38°C).

Remote Balancing Dampers
Pre-Installation Guidelines
The basic intent of a proper installation is to secure the
remote balancing damper in 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 actuators.
3) Do not install screws in damper frame that will interfere
with blade linkage or 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 and actuator must be kept clean 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
7) Damper should be sufficiently covered as to prevent
overspray if wall texturing or spray painting will be
performed within 5 feet of the damper. Excessive dirt
or foreign material deposits on damper can cause
excessive leakage and/or torque requirements to
exceed damper/actuator design.
Installation Instructions
Round, RBDR series, dampers are supplied from the factory
with the actuator installed see Figure 1.
Square/rectangular, RBD series, dampers are supplied with
an actuator kit that must be field installed as follows:
1) Install the RBD series damper into the ductwork with the
lanced end of the blade positioned to the side of the duct
where the actuator is to be located (see Figure 2).
2) Drill a minimum 9/16 in. (14mm) diameter hole that lines
up with the center pivot of the damper blade.
3) Insert the pointed end of the pin through the hole and into
the blade lances. Pound pin into the blade lances until the
end of the pin is ½ in. (13mm) outside of the duct surface
while the blade is centered in the damper frame.
