4. If DUCT ADAPTER is already attached to housing, disregard Item #4. If not proceed as follows! Attach DUCT
ADAPTER to housing by first hooking mounting flange over edge of air discharge opening. Pivot duct adapter
insuring (2) aligning tabs are inside opening and align (2) locking tabs with small rectangular holes. Press tabs
firmly into holes to lock. See Fig. 3. Remove tape securing damper.
NOTE: The attachment of the duct adapter to the housing may be reinforced, if desired, by
installing a #8AB screw through the oblong hole in the duct adapter and the small round
hole in the housing.
5. Insert (4) mounting brackets with angles pointing away from housing. In approximate location between joist where
housing will be located, drive (2) nails (4D or 6D) 1” from bottom of joist, 11” apart leaving 1/4” of nail projecting.
Position one set of mounting brackets over nails and drop into place. Extend the remaining mounting brackets to
the adjacent joist and repeat nailing procedure. Finish driving nails and adjust housing between ceiling joist.
See Fig. 10.
6. Run 120V A C, 60 Hz power cables from wall switch/switches to appropriate knockout in housing. Use a BX or
Romex connector. (Refer to wiring diagram designated for the model being installed.) Connect cables from wall

in outlet box. Install outlet box cover and secure with screw provided.
7. Run four inch duct from discharge outlet to roof jack or wall cap. See Figs. 6 & 7.
