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 either the four #12 screws provided with the damper
assembly (for general installation) or the four #10 machine screws and nuts (for project pack
installation). The mounting flange of the fan should be aligned with the mounting flange of
the damper assembly (refer to Figure 2).
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 screws.
3. If the damper is to be used with a fan not equipped with a lighted grille, attach the same
bracket mentioned in step 2 to the frame in the same manner. 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 manufacturer.
