Disassembly
Host Fixture
Shell
The disassembly involves removing and discarding the
door/louver of the host fixture and all of the internal
components. Dispose of according to state and local
code requirements. Please recycle all reusable parts.
1. Shut off power to existing fixture. Disconnect the black
and the white power supply wires to existing ballast.
2. Remove and discard the host fixture door/louver.
3. Remove and discard the host fixture interior parts.
Remove door/louver, ballast
cover, socket bars, lampholders,
ballast and wiring.
Remove the lamps. Remove the ballast cover.
Remove the socket-bars, sockets, ballast
and the wiring between the ballast and the
sockets.
Assembly
1. Install the End Rails
One End Rail is installed at each end of the
host fixture. The End Rail nests between
the T-bar ceiling grid and the host fixture
housing. Start with the rail positioned at an
angle relative to the fixture endplate and
insert one end into the corner (Fig. 1).
Now position the opposite end of the End
Rail between the T-bar and the fixture
housing and slide it toward the end of the
fixture. Seat the End Rail firmly against the
ceiling grid (Fig. 2). Repeat this procedure
for the other end of the fixture.
Figure 1
Start with Mounting Rail at a slight angle, nested between the ceiling grid T-bar and the fixture housing
2. Install the Side Rails
The Side Rails install in a similar manner as
the end rails. Start with the Side Rail at an
angle with one end nested between the
End Rail and the ceiling grid. Now press the
Side Rail against the ceiling grid until it is
fully seated.

Entry
3. Suspend the LED Retrofit Insert from the Mounting Rails
Position the LED Retrofit Insert in the host fixture opening so
the driver is on the same end as the branch wiring entry point.
With the Insert positioned vertically, insert the Hinge Pin on
one end of the LED Retrofit Insert into the pivot hole in the
Mounting Rail (Fig. 4).
Hinge Pin
Align the Hinge Pin on the opposite corner with the slot in
the Mounting Rail and slide the LED Retrofit Insert toward the
corner of the host fixture until both Hinge Pins are located in
the pivot holes.
4. Connect Bonding Tether
Using the factory supplied self-drilling screw, use a drill to
attach the free end of the bonding tether to the host fixture
housing. The tether placement should be like that shown in
Figure 5. Insure that screw is torqued to 14 inch pounds.

5. Make Electrical Connections
Using the factory supplied wire nuts, connect the black lead
from the electrical disconnect to the black branch wire and
connect the white lead from the electrical disconnect to the
white branch lead (see Appendix on next page for wiring diagrams).
6. Finalize installation of the LED Retrofit Insert.
Complete the installation by rotating the LED Retrofit Insert
so it is flush with the ceiling and secure it by rotating the
latches (Fig. 6).
