OVERVIEW
Read through the entire Installation Instructions prior to beginning the installation.
A. GRID INSTALLATION
The MultiForm luminaire is designed to install into standard suspended grid
ceilings with a 1" or 1½" high grid. The weight of the luminaire is supported by
the grid and supplemented with direct connection to the building structure. The
steps for installation are as follows:
1.Inspect the ceiling grid to make sure it is supported from the building structure as recommended by the ceiling grid manufacturer’s instructions. 2.Angle the fixture up through the opening in the grid. Once through the
opening, lower the luminaire so that its flanges are supported on the ceiling grid.
3.The luminaire is to be connected directly to the building structure, independent of the ceiling grid. Locate the hanger support tab at each corner of the luminaire housing and bend the tab. Use a hanger wire at all four corners to tie the luminaire to the building structure. Use 12 gauge minimum hanger wire rated for such application. In addition, follow local building codes regarding required additional support of luminaires.
4.Proceed to section “C. Making Electrical Connections”. B. FLANGE INSTALLATION
The MultiForm luminaire can
be installed into a drywall (i.e.
gypsum board, sheetrock)
ceiling with the addition of the
flange kit option. The steps for
installation are as follows:
1.A flange installation requires a clean and accurate opening of 24¼" x 24¼" to be cut into the ceiling surface Typical Corner Detail
where the luminaire is to be installed. Openings need to
be cut square and accurate. It is recommended that the opening should be cut into whole pieces of ceiling material to minimize seams Figure 3
and joints intersecting the cut opening. This limits stress on taped joints and ensures a better fit of the fixture flange against the ceiling surface.
2.Assemble the flange kit by sliding the (snap-lock) corner angles into side and end rails as shown in Figure 2.
3.Place assembled frame into ceiling opening and wire support (at four corners as shown in Figure 2) from main floor/ceiling structure.
4.Angle the fixture up through the opening in the frame. Once through the opening, lower the luminaire so that the fixture flanges are supported on the flanges of the flange kit.
5.Proceed to section “C. Making Electrical Connections.

Note: The circuit should be shut-off at the breaker before
beginning this step.
1.Open the door by fully loosening the two thumbscrews. Allow the door to swing open.
Figure 3
2.Remove the reflector plate by removing the four (4) screws. The fixture wiring should be exposed at this point.
3.Locate the knockouts on the back of the housing. Remove one of the knockouts.
4.Secure the flexible metal conduit (FMC) with the incoming power at the location of the removed knockout with the appropriate conduit connector. Locate the leads for the exam load. (These leads are tagged for easy identification.) There may be an additional set of leads for the nightlight option.
5.Make the electrical connections by connecting the building hot to the black lead, the building neutral to the white lead and the building ground to the ground lead.

D. INSTALLING LAMPS
1.Exam Compartment
a.Hand loosen the two (2) thumb screws for the exam compartment door. Allow door to hang open from the fixture.
b.Angle the lamp so that it fits into the fixture housing. Begin inserting the lamp’s socket into the lampholder from the side of the lampholder so that the 4 pins on
the lamp align with the pin holes on the lampholder. Begin to move the tip of the lamp horizontally until
the lamp’s socket aligns with the lampholder. Gently push the lamp into the lampholder until it fully engages. Once in place, push the tip of the lamp over
the lamp support clip.
c.Repeat this same step for the other lamps in this compartment.
d.Close the exam compartment door and hand tighten the two (2) thumbscrews.
