Preparing the Installation Location
1.
Power down
all attached devices before proceeding.
2.
Using the provided cutout template for the outline,
cut
a hole for the BCK SF 26CT
in the ceiling tile, as
described below.
NOTE:
For hard ceiling installations:
Skip
steps a through e
and just use the
template to cut a hole in the ceiling.
a.
Remove the ceiling tile, and draw diagonal lines
across it from opposite corners to locate its center.
Mark the intersection where the lines cross.
b.
Position the center hole of the cutout template
directly over the center of the tile, marked in
step 2a.
c.
Trace a circle on the ceiling tile around the cutout
template.
d.
Cut out the circle traced in the ceiling tile.
e.
Replace the ceiling tile in the ceiling.
3.
Attach two V-rails and one C-ring
above the hole cut
in step
2
, as described below.
NOTE:
For hard ceiling installations:
•
Fold one C-ring assembly in half and insert it
through the hole in the ceiling.
•
Unfold the C-ring and center it over the hole
with the flat side down.
•
V-rails are not needed.
a.
Assemble two V-rail half sections by fitting the tab
of one end into the slot of the other end. Open the
V-rail until it locks together (see figure 1). Repeat
this procedure for the other V-rail.
b.
For ease of access, Remove a ceiling tile adjacent
to the cut tile.
c.
Place both assembled V-rails on the cut ceiling tile
and position them equally on either side of the hole.
The ends of the V-rails go over the ceiling grid (see
figure 2, on next page).
