4. Cut the ceiling tile
a. Mark the location of the PCM 240 on the T-bar, before
removing it. 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-bar runners to the
center of the Pipe Adapter Plate.
c. Using these dimensions, mark and cut a hole for the
PMP in the ceiling tile.
T Place the tile on a box, mark hole 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. Finish Projector Ceiling Mount
installation
a. Loosen the set screws and unscrew the UPB 25 from the
mounting pole. Do not remove the projector bracket
from the projector.
b. Loosen the PCM 240 ‘s set screw and remove the
mounting pole, then remove the PCM 240.
c. Replace the cut ceiling tile, checking the orientation to
align the hole with the PCM 240.
d. Replace the PCM 240 over the ceiling tile and screw
the mounting pole (with the access hole uppermost) up
through the hole into the mounting plate. Tighten the set
screws.
