Receiving and Handling
Check for obvious and hidden package damage after receiving. Check to be sure that all
parts of the shipment, including accessories, are in the package. Dampers must be kept
clean and dry. Indoor storage and protection from dirt is highly recommended.
Storage of Dampers Prior to Installation
:
The intent of a proper storage of heavy duty industrial control damper is to prevent
physical damage, material corrosion and deterioration of organic material.
A. After visually inspecting the damper for damage, store indoors, protect from sunlight,
moisture and flooding. Protect dampers from debris and dirt accumulation. Keep all
conduit entry plugs and actuator access covers in place.
B. Dampers may be stored and stacked horizontally if wood or equivalent spacers are
placed between flanges. Do NOT store with axles vertical. Place dampers on pallets
or supports to allow air circulation.
C. Consult manufacturer if storage time exceeds two years.
General
The following guidelines provide basic assembly installation instructions for models
TICD-51/52, TICD-51/52BF, TICD-51/52BFX thermally insulated dampers.
(
Failure to follow instructions will void warranty).
Fig. 1
A. Dampers are supplied standard without mounting holes (Fig. 1). Drill or punch as
required.
B. If mounting holes are supplied, use appropriate gasketing between mating flanges.
Closed cell sponge rubber, solid rubber, maximum 60 durometer, or fiberglass drop warp
tape is recommended.
C. Dampers are to be installed square, straight and to flat surface to prevent binding
during operation. Damper must not be stretched or squeezed into duct or opening.
Racked, out of square, twisted or misaligned installation can cause excessive torque and
torque requirements that exceed damper design.
D. Mating flange must be flat and in the same plane.
E. If the new damper is replacing an existing damper, clean mating surfaces prior to
installing new damper.
F. Damper blades will open past the frame depth.
G. Damper may be installed with flow from either direction.
H. Damper blade must be horizontal.
I. Isolate damper from high vibratory loadings.
J. Install all mounting bolts before tightening. Tighten in even and staggered pattern to
evenly compress flange gasketing.
K. Ensure that the bolts or screws used for installation do not interfere with linkage.
L. When blade is in the open position, verify that damper does not strike mating duct-
work or internal ductwork reinforcing. Clearance of

shall be from the inside of the
damper to the inside of duct.
M. Most common types of installation - standard flange out of opening (Fig. 2), standard
flange inside opening (Fig. 3) and extended flange (Fig. 4).
Duct
Don’ts
A. Do not use axles, linkage, or actuator as lifting point.
B. Do not lift damper with chain/strap with blade open and with chain/strap through frame as this could damage blade and stop seal.
C. Do not tighten mounting bolts around the damper by starting at one point as uneven flange compression can result.
D. Do not use prybar to match frame holes to matching ductwork as frame can be warped or pulled out-of-round by excessive force.

Installation Guidelines
Pottorff Dampers are designed to be trouble and hassle free under normal operation. The intent of a proper installation is to secure the control 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.
