4. Cut the ceiling tile
a. Mark the location of the PCM 340 on the T-frame. This
aids putting it back in the correct location when the tile is
replaced.
T Mark the screen direction on back of the tile (e.g. with
an arrow or “to front”) to help orientation of tile when
replacing it after cutting.
b. Measure the distances X and Y (see figure) from the inner
vertical section of the front and left T-frame runners to
the center of the Pipe Adapter Plate.
c. Using the X and Y dimensions, mark and cut a hole for
the slotted pipe in the ceiling tile.
T Place the tile on a box and mark the hole’s center on
the underside of the tile. Use a hole saw bit to start to
cut the hole by hand (turning bit counter clockwise) to
avoid damaging the tile. When the drill bit is through
the tile, turn the tile over and finish cutting from the
top side.
5. Preliminary safety hardware installation
a . Mark and drill holes at 10 degrees out from vertical for
each turnbuckle. Drill a fifth hole directly centered above
the PCM 340 for the safety cable.
b. Install an appropriate anchors or lag eye bolt for the
structural ceiling into each drilled hole.
