FOR BEST RESULTS
In a new construction site, install the housing during rough-in
construction of the building. The blower assembly, light, and grille
should be installed when the finished ceiling is in place.
Installation in an existing, finished building requires an accessible
area (attic or crawl space) above the planned location. See
“INSTALLATION IN EXISTING CONSTRUCTION.”
