NEW HOME INSTALLATION
1. Carefully remove unit from carton. Place grille in a safe location until needed. Remove ship-
ping tape from air discharge backdraft damper.
2. Position housing against joist. Housing is stamped to show a line at 3/4” for standard
sheetrock and plaster and 3/8” for drywall. (See Figs. 2 & 3). Drive pre-assembled screws on
mounting brackets to secure housing. There are two tabs opposite each mounting bracket to
provide additional support. If the unit is mounted for 3/8” clearance, the small tab remains in
place. If mounted for 3/4” clearance, the smaller tab is bent out of the way to expose the larger
box.
3. Run 120VAC, 60Hz power leads from wall switch or Model 1011 timer to appropriate knockout
in housing. Use a BX of Romex connector on outlet box.
4. Remove outlet box cover by pulling downward while simultaneously pushing in side of cover
at indicated point to release locking tab. Connect wire from wall switch to motor wire using
approved wire connectors - white to white, black to black. Remove grounding clip and insert
ground wire. (See Fig. 6) Push or tap clip into notch in housing. Cut off excess ground wire.
Replace outlet box cover insuring locking tab is engaged.
