1. Install the radiation damper onto the inlet side of the fan so that the holes in the sleeve align

with mounting holes on the fan using the four #10-32 x ¼” long screws provided with the

damper assembly (general installation). The mounting holes of the fan should be aligned with

the mounting holes of the damper assembly (refer to Figure 1).

2. For a damper used with a fan equipped with a grill light, route the wire from the grille

through the notch on the damper frame. Use the supplied bracket to secure the wire to the

damper frame. Attach the bracket to the frame using one of the supplied #8-18 screw (see

Figure 3)

3. If the damper is to be used with a fan not equipped with a lighted grille, attach the same wire

bracket (rotated 180°) to the frame using the supplied #8-18 screw as seen in Figure 2.

Ensure that the bracket covers the notch in the frame.

4. Once the damper assembly is secured to the fan, turn it over so that the damper is at the

bottom. The fan can now be installed by two methods. The first is by utilizing vertical

hangar wires, minimum 12 SWG (2.7), attached to the damper sleeve (require one per side).

The second is to use the suspension bracket assembly provided by the fan manufacture (sold

separately).

The penetration in the ceiling should be located within the ceiling tiles or panels without necessitating cuts in the ceiling suspension main runners or cross tees. If a cut is needed, a maximum of one runner or cross tee may be cut to enable proper damper location and installation. Each cut end shall be supported by a min 12 SWG (2.7) vertical hanger wire.
