1. Cut ceiling tile
If installing PV SI 3C LP speakers, do the following:
a.
Remove the ceiling tiles where the speakers are to be
installed.
T For ease of working on the speaker when it is replaced
on the T-bar, remove an adjacent tile(s).
b. Locate the tile center, and using the supplied template,
trace and cut the hole for the speaker.
T Place an empty box under the tile for support and to
collect the waste.
Measure and mark the center point of the tile and align
the cross marks with those on the supplied template.
Use a fine hacksaw blade to cut the tile without
damaging the face.
2. Install the speaker in the ceiling tile
a. Lay two supplied speaker V-rails across the tile on either
side of the hole.
b. Remove the C-ring from the speakers and attach it to the
center of the V-rails with the supplied hardware.
T At the ends of each V-rail, bend the tabs upwards.
This makes it easier when replacing the tile back on the
T-bars. When installation is complete, bend the V-tabs
down onto the T-bars
