2. SLEEVE LENGTH AND WALL/FLOOR THICKNESS

Insert the damper assembly into the prepared opening, to appropriate depth (see Page 3, Fig. 1).

Recommended maximum and minimum insertion depth can be exceeded if:

1) the operation of the damper actuator is not impeded and

2) the C of the damper blade remains within the

L

plane of the wall/floor

important safety dANGER! : To avoid causing death or serious bodily harm to building occupants, do not insert screws into the damper frame unless used for duct connection within 2 in. of the frame end.

The sleeve may extend a maximum of 16 in. beyond the wall or floor on the actuator side of the damper and a maximum of 6 in. on the opposite side.

3.DUCT TO SLEEVE CONNECTIONS

Dampers are supplied with sleeves and actuators from the factory and can be installed without the need for additional field installed sleeves.

Gauge of factory furnished sleeve determines the type of duct to sleeve connections required (see table below). Any duct connection other than the breakaway connections are considered rigid.

4.SECURING THE DAMPER/SLEEVE ASSEMBLY TO WALL AND FLOOR OPENINGS

Damper assemblies must be installed in wall/floor openings using a single retaining plate on either side of the wall/floor or by using a retaining plate on both sides of the wall/floor. The use of a second retaining plate is allowed, but is not necessary. A single retaining plate is provided with the dampers. A second retaining plate can be ordered as an option. The outside dimension of the supplied retainer plate is nominal dia. + 4.50”.

•The retaining plate(s) will open up for easy installation when the clamping screw is loosened. If necessary, remove the clamping screw and nut (see Fig. 2).

(IMPORTANT: The clamping mechanism should face away from the wall/floor). Retainer plate(s) are designed to mount flush to the wall/floor and hold the damper in the wall/floor opening.

•Place the damper and attached retainer plate into the wall/floor opening.

•If a second retaining plate is being used, secure it on the opposite side of the wall/floor

DO NOT POSITION RETAINER PLATE(S) IN FRAME GROOVE

•Verify position, blade orientation, and actuator clearance then tighten the retainer plate clamping screws. The retainer plate(s) must overlap the wall/floor opening a minimum

of 1 inch. Secure the retainer plate(s) to the wall using appropriate fasteners (minimum #8 sheet metal screws) at the four corners of each retainer plate when two retainer plates are used and also within 3⁄4 in. of the center of each plate when one retainer plate is used.
