DROP CEILING INSTALLATION
NOTE: Drop ceiling installations are similar to new construction
installations, except the hanger bars are attached to the T-bars of a drop
ceiling grid, instead of ceiling joists, as described below.
T-BAR INSTALLATION (Fig. 12)
1. Install a ceiling tile onto the T-bar grid at the installation location. Using the
provided template and a keyhole saw make a hole at the desired location in
the ceiling tile.
2. Place the plaster frame/hanger bar assembly onto the ceiling tile into the
newly created hole, making sure the bottom of the plaster frame feeds
through the hole. Adjust the width of both hanger bars to the distance
between the two T-bars, aligning each mounting clip with the top of its
corresponding T-bar. Press down on all mounting clips until they snap onto
the T-bar.
NOTE: Holes are provided on the mounting clips that can be
used to secure the hanger bars to the T-bar. Parts (I.e. screws, hex nuts)
can be purchased separately for this purpose.

3. Proceed to Step 3 of the "CEILING JOIST INSTALLATION" section.
ELECTRICAL CONNECTIONS (Fig. 13 & 14)
1. Open the junction box's door by pulling on its metal tab.
2. Break off one of the round knockouts from the junction box using a
screwdriver.
Secure an appropriately sized BX or NM (Romex) cable
connector to the knockout opening. Feed the BX or NM (Romex) cable
through the connector, providing 3" (7,6 cm) of slack inside the junction
box. Tighten the connector to secure the cable in place.
3. Remove at least 3" (7,6 cm) of the cable's outer sheath and remove the
plastic or paper over-wrap. Strip approximately 3/8" (1,0 cm) of insulation
from the ends of all supply wires. Using wire nuts, make the following wire
connections:
WHITE SUPPLY WIRE (NEUTRAL)
BLACK SUPPLY WIRE (HOT)
GREEN/BARE SUPPLY WIRE (GRND)
Be sure that there are no loose strands or loose wires.
4. Wrap all wire connections with electrical tape for a more secure
connection.
NOTE: If you have electrical questions, consult your
local electrical code for approved grounding methods.
5. Carefully stuff all wires and wire connections into the junction box. Close
the junction box's door.

NOTE: In additional to the main supply cable entering the junction box, one
more cable may be fed into the junction box to provide electrical power to
another light fixture intended to be on the same circuit. No more than two
cables can be fed into the junction box. It is very important that the knockout
used for the second cable be adjacent to the knockout used for the first
cable. Avoid using a knockout that is on the opposite side of the first
knockout.
Using an opposite knockout may make insertion through the
ceiling hole more difficult.
LIGHT BULB AND TRIM INSTALLATION (Fig. 15, 16, 17 & 18)
1. Follow one of the figures below to install the trim and light bulb.
2. To install the trim, squeeze both torsion springs together and insert into
the can's receiver brackets and release. Carefully push the trim into can.
3. Installation is complete. Restore electrical power.
