1. Open package containing Ceiling Radiation Damper
(CRD), plaster flange and sleeve. Ensure tabs on
sleeve are folded over damper frame.
2. Using the (4) Tinnerman U-Clips provided, secure
the CRD to the sleeve aligning the Tinnerman clips
with the 0.25" holes on the sleeve. Position each
Tinnerman U-Clip such that the retaining side is
located on the exterior of the damper frame.
3. Position the CRD-300WT on the SP-LP Fan
Assembly so that the wire chase on the CRD is
located to the left of the fan's junction box.
4. Install CRD-300WT onto the SP-LP Fan Assembly
using three (3) screws / lock nuts and one (1) duct
connector screw supplied. Locate screw heads on
the same side as the damper.
5. Next, hand form the mounting flange on the sleeve
up 90 degrees. Install (2) 1" x 1" x 16GA mounting
angles (figure 7, field supplied) by securing with
(4) self-tapping screws provided with SP-LP
fan assembly. Distance between wood trusses
determines length of mounting angles.

6. Install the fan/damper assembly, with attached
mounting angles, between the trusses as shown
in Figure 4 and attach mounting angles to the
trusses using 4 - 11/4 in. long steel screws per
mounting angle.
7. Refer to the fan IOM for wiring.
8. Cut a 10.5" square hole in the gypsum board for the
fan/CRD assembly. Install ceiling gypsum board.
9. Secure the plaster flange onto the fan/CRD
assembly by fastening the (4) self-tapping screws
provided into the Tinnerman clips installed in step 2.
10. Mount one side of the grille by inserting the grille
springs into the slot on the plaster flange located on
the wiring side of the fan.
11. Install the wire retaining bracket with the remaining
(1) self-tapping screw.
a. When using a grille without light or motion sensor
align the flat of the wire retaining bracket with the
wire chase.
b. If using a lighted grille and/or motion sensor,
plug in the Light and/or motion sensor into
receptacle(s) in the fan housing. Install the wire
retaining bracket around the wires aligned with
the wire chase.
CAUTION
Ensure all wires are clear of the damper operation.
12. Insert the other grille spring into the slot on the
plaster flange opposite the one previously installed.
