INSTALL THE HOUSING
1. Choose the location for your fan in the ceiling. For best possible
performance, use the shortest possible duct run and a minimum
number of elbows.
2. Position mounting brackets against joist so that bottom
edge of housing will be flush with finished ceiling.
Additional positioning feature for 5/8”, 1”, & 1-1/4”
thick ceiling material:
Holes in corners of housing are labeled with various
ceiling material thicknesses. Position housing so bottom
edge of joist is visible through a matched set of holes.
The housing is now in the proper position for that ceiling
material thickness.
Additional positioning feature for 1/2” thick ceiling
material:
Bend two tabs, on side of housing, 90 0 outward. Lift
housing until tabs contact underside of joist.
Mark the keyhole slot on both mounting brackets.
3. Set housing aside and drive nails partially into joist at the top of
both keyhole marks.
4. Hang housing from nails and pound nails tight. To ensure a noise-
free mount, pound another nail through the top hole of each
mounting tab.
