IN-CEILING INSTALLATION
Type: IC-2
Mounting Hardware
The table at right lists the correct
enclosure mounts to use for installation
into ceiling cavities with joist widths
ranging from greater than 17 ½-inches
to 25 ½-inches on center. Before
proceeding, identify and familiarize
yourself with the appropriate mounts
for your specific installation.
Install Joist Mounting Brackets
Mark the bottom edge of each
ceiling joist at the desired position
of the center of the driver/grille
within the floor plan.
Note: From
this mark, there must be at least
17-inches of unobstructed space
to the nearest obstacle and at least
41-inches of unobstructed space
in the opposite direction.
Next,
place a second mark 25-inches away
from each of the first marks.
Position the Joist Mounting
Brackets (Parts E & F) at the inscribed
marks and fully install three #8 x
1.25-inch wafer head screws into
each.
Note: Ensure that all ends of
the mounting brackets are oriented
as shown with the long side of each
bracket flush with the inside face of
each joist.
