opening in housing.
NOTE: The cardboard protector shields the inside of the housing
from drywall spray and construction dust. Do not remove it until
after construction is completed.
2. Mark mounting location.
Position unit between joists and extend mounting brackets.
IMPORTANT: Position brackets so there will be an 1/8" gap
between bottom of housing and ceiling material. Mark the top of
keyhole slot on all four mounting brackets.
3. Pound in nails.
Remove unit temporarily, and pound
nails partially into joists at all four
marked locations.
4. Hang and secure housing.
Hang unit from nails. Check to make
sure that there will be a 1/8" gap
between bottom of housing and
ceiling material. Pound nails tight.
For wide joist centers: A #8 x 3/8
self-tapping screw can be used to
join extended brackets together and
