Installing the PCM 240

Before starting, check that all the parts received match the supplied parts list (see “PCM 240 kit contents” table, page 10).

Preparing the ceiling

WThe PCM 240 must not be supported by the suspended ceiling itself. It must be secured to and suspended from the structural ceiling above.

WCheck the structural ceiling to ensure that it can handle a load four times the weight of the final setup.

NRefer to local building standards and codes to verify that the installation will meet all the regulatory requirements.

Identify the location for projector placement. Remove the ceiling tiles adjacent to the tile where the projector will be mounted. This will allow easy and safe access while installing the projector mount.

Inspect the structural ceiling where the projector mount will be installed to ensure there are no cracks or weaknesses that could jeopardize the completed installation. Select the correct installation hardware from those supplied. Hardware for each of three methods of hanging and securing the PCM 240 is supplied:

•Turnbuckles and tie wire tied to concrete anchors for concrete structures

•Turnbuckles and tie wire tied to eye screws for joists

•Turnbuckles and tie wire wrapped around wooden trusses.

Alternatively, threaded rods (not supplied) may be used to secure the mount to the ceiling structure. Safety cable is provided to hold the mount up in the event that any tie wire or rods become loose or detached as a result of an earthquake or accident.

Installing the projector ceiling mount

1.Screw the four T-bar securing screws loosely into the ends of the mounting plate (see figure 2).

2.Place the mounting plate over the selected ceiling tile and lower onto the T-bar. Adjust to the position desired and lightly tighten the T-bar securing screws to the frame.

3.Adjust the sliding pipe adapter plate to the precise position for the mounting pole, and tighten down the locking nuts.

4.Using the hole in the pipe adapter plate as a guide, mark the ceiling tile where the mounting pole will pass through it. If electrical boxes are also to be installed, mark the ceiling tile where the cut-outs will be.

5.Loosen the T-bar securing screws and remove the mounting plate.

6.Remove the tile, and carefully cut out the marked area(s).

7.Replace the ceiling tile.

NBe sure to place the ceiling tile back in the same T-bar square, with the same orientation as it had originally. Failure to do so will result in misalignment of the projector.

8.Attach any 3" deep, ¼ rack devices or electrical boxes required onto the mounting plate. Depending on the situation, this may be easier to do after the plate is fully installed.

CUsing flex conduit is recommended when installing any power wiring.
