8. Install the electrical box (if required)
W All electrical installation should be
performed by qualified personnel in
accordance with local and national
building codes, fire and safety codes,
and local and national electrical codes.
If required, the following method is recommended for
integrating a 4S Raco electrical box (not supplied) on the
PCM base plate (e.g., a Raco 231, 2 1/8 inch deep, 4x4 inch
electrical box and a Raco 778, 1/2 inch raised, 4x4 inch
plaster ring or similar).
Install the Raco box on the PCM plate as follows:
a
. Attach the box to the plate, using the smallest notches
in opposite corners of the cut-out (see figure 8a). Do not
tighten the screws fully at this time.
b . On the opposite side of the PCM plate, slide the plaster
ring under the screws. The plaster ring anchors the box
in place with PCM plate sandwiched between.
c . Fully tighten the screws.
W For safety, complete all wiring of the
electrical boxes and accessories after the
plate is fully installed and secure.
d . Mark and cut a hole in the ceiling tile for the electrical
box opening.
9. Install the Screen

to install the screen mounting brackets and then hang the
screen.
T Use S-hooks to hang the screen from the brackets. Bend
the ends of the S-hooks so the screen does not fall when
it is rolled up.
