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 Figure 1). Do not drag, step on, apply excessive

bending, twisting, or racking.

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 prevent free operation.

5) Damper 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) Drywall/mortar dust

b) Firesafing materials

c) Wall texture

d) Paint overspray

6) Damper should be sufficiently covered as to prevent overspray if wall texturing or spray painting will be performed

within 5 feet (1.50m) of the damper.
