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 ½” long screws and 10-32 nuts
provided with the damper assembly (general installation). The mounting flange of the fan
should be aligned with the mounting flange 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
