Product Usage Instructions

TURN OFF THE POWER! Before starting the installation process, turn off the power to avoid the risk of electric shock.
Remove lens and hardware kit from fixture.
Press in the middle of the lens on one end to lower the lens below the locating feature in the endcap. Slide the lens into the endcap to create a gap between the lens and endcap on the opposite end of the fixture. Use the exposed gap to gently reach under the lens and pull it away from the fixture to remove it. Set the lens aside in a location where it will not fall or become damaged. Remove the bag with the hardware kit from inside of the fixture.
Prepare for fixture mounting. The fixture must be centered over and mounted to the electrical junction box. If additional support is required, mounting locations at ends of fixture are provided. Have someone assist in holding the fixture against the ceiling. With fixture junction box mounting holes lined up with junction box, mark the end mounting locations on the ceiling. Use appropriate hardware for the ceiling type that fixture is being mounted to. Typical installation onto a drywall ceiling will use drywall anchors rated to hold at least 20 lbs.
For 2-3/4 electrical box only: Use a screwdriver to knock out covers in housing for additional mounting slots. Pliers may be necessary to bend knockout several times to remove.
Partially thread screws (provided with junction box or 2x 8-32×1 screws provided in hardware kit) into the junction box. Leave the head of the screw approximately 1/4 away from the box (do not tighten).

INSTALLATION

Step One:
TURN OFF THE POWER!

Step Two:
Remove lens and hardware kit from fixture –
Press in middle of lens (A) on one end to lower lens below locating feature in endcap.
Slide lens into endcap (B) to create gap between lens and endcap on opposite end of fixture (C)
Use exposed gap to gently reach under lens and pull away from fixture to remove (D).
Set lens aside in a location where it will not fall or become damaged.
Remove bag with hardware kit from inside of fixture.

Step Three:
Prepare for fixture mounting –
The fixture must be centered over, and mounted to, the electrical junction box.
If additional support is required, mounting locations at ends of fixture are provided.
Have someone assist in holding the fixture against the ceiling.
With fixture junction box mounting holes lined up with junction box, mark the end mounting locations on the ceiling.
Use appropriate hardware for the ceiling type that fixture is being mounted to.
Typical installation onto a drywall ceiling will use drywall anchors rated to hold at least 20 lbs.

For 2-3/4” electrical box only:
Use screwdriver to knock out covers in housing for additional mounting slots.
Pliers may be necessary to bend knockout several times to remove. For all installs – partially thread screws (provided with junction box or 2x 8-32×1” screws provided in hardware kit) into junction box. Leave head of screw approximately 1/4″ away from box (do not tighten).

Step Four:
Make electrical connections in junction box –
DO NOT MAKE CONNECTIONS IN FIXTURE

Connect the hot and neutral (black and white) wires from the junction box to the corresponding wire colors from the fixture, using the provided wire nuts.

Also, connect the ground wire (green) from the fixture to the circuit ground using a wire nut.

Step Five:
Attach fixture to junction box –
Position wires and connections up into junction box.
Lift fixture up and align larger opening of keyhole with heads of partially threaded screws from Step Three. Rotate fixture clockwise and tighten screws to secure housing to junction box.
Use appropriate fasteners at ends of fixture if required.

Step Six:
Reassemble lens to housing –
Start with lens parallel to fixture as shown below. With the end of lens 3-4 inches away from the endcap. Support middle of lens up against fixture with one hand.
– Begin at the end of fixture with lens-endcap gap, place lens groove around flange of housing (A).
Apply pressure to keep this edge pressed against flange.

Next, flex first 1-2 feet of the other long edge of lens under flange and inside the housing (B). Lens can withstand significant bending without breaking.
Then, pull gently on lens (C) to clip lens groove around flange of housing (D). If lens pops out, please repeat this step from the beginning.
Finally; slide lens towards, and under, endcap (E).
This should seat the lens groove around the housing flange down the length of the lens.
Adjust any un-seated sections of lens groove to housing along the length of the fixture on both sides of lens. Center lens under endcaps so that no gaps exist.
