MOUNTING PAN INSTALLATION
Step 1: NEW CONSTRUCTION: Pre-attach the specified mounting
hardware to the fixture pan. See FIGURES 1.1 - 1.3.
REMODEL: With the expandable bar hangers removed, maneuver
the receiver bracket assembly up through the ceiling cutout.
Once in the ceiling, reinstall the bar hangers, then position the
receiver bracket assembly 2” from the ceiling opening. Expand
the universal bar hangers until they stop against the ceiling joists
(both sides), then use a hammer to tap the nailer tabs into the
joists. See FIGURE 1.4.

MOUNTING PAN INSTALLATION CONTINUED FROM PREVIOUS PAGE
Step 2: Install pan assembly as required for ceiling structure while
aligning the pan aperture with the ceiling cutout.
SCA INSTALLATION: Install the SCA mounting pan with the
driver box mounting rails located uphill from the ceiling cutout.
Use the height adjustment screws to adjust the depth of the
locating fingers so they are both flush with the ceiling plane.
Securely tighten the height adjustment screws. See FIGURE 2.1.
Orient yoke arm brackets parallel to the horizontal plane. See

Step 3: Route the flexible metal conduit containing all of the required
power input and control leads to the pan location. Leave
enough length for pulling at least one foot below the ceiling
plane through the ceiling cutout.
ELECTRICAL CONNECTIONS
Step 4: Connect driver box to conduit
A. Pull the flexible conduit down through the ceiling cutout
and connect the driver box via the small access cover, see

B. Make all necessary lead terminations within the box.
Attach power supply and ground wires using UL listed wire
connectors. Ballast disconnect accepts #12 - #16 AWG
stranded or solid wire. Re-attach the access cover. Please
consult factory for other driver configurations or emergency
driver wiring diagrams.
Note: The bottom panel of the driver box can be removed to
assist with making lead terminations if needed.

DRIVER BOX INSTALLATION
Step 5: Install driver box to mounting pan (see FIGURE 5.1 )
A. FOR NEW CONSTRUCTION ONLY: Maneuver the driver
box up through the ceiling cutout, rotate down 90 degrees,
then slide back between the mounting pan rails until it hits a
physical stop.
FOR REMODEL ONLY: Install junction box in ceiling plenum.
(see FIGURE 5.2) Maneuver the driver box up through the
ceiling cutout, place on the receiver bracket assembly.
B. Reach up through the ceiling cutout and thread in the (2)
thumb screws to secure the driver box to the pan.

C. Pull the LED power cable and steel leader down through
the ceiling cutout so they are accessible for the downlight
insert installation.
SCA TRIM INSTALLATION
(SKIP TO STEP 8 FOR STANDARD CEILING INSTALLATION)
Step 6: Orient and align sloped ceiling trim. Align the trim mounting
screws (2x) with the pre-installed cage nuts located in the yoke
arm brackets. See FIGURE 6.1
Note: The lower stop ring must run parallel with the yoke arm
brackets

Step 7: Install sloped ceiling trim
A. Lift the sloped ceiling trim up into the ceiling cutout so the
mounting screws can engage the cage nuts.
B. Tighten the screws until the trim flange has been drawn
securely against the ceiling surface.
C. Pull the LED power cable and steel leader from the driver
box down through the sloped ceiling so they are accessible
for the downlight insert installation. See FIGURE 7.1

DOWNLIGHT INSERT INSTALLATION
Step 8: Connect downlight insert to power (see FIGURE 8.1)
A. Connect the steel leader to the wire lanyard so the
downlight insert is supported. The fixture will need to
remain supported for remodel installations.
B. Terminate all LED power cables (from 2-5) to the
corresponding LED input cables on the downlight insert.
Note: During insert installation, always orient the LED input
cables toward the installed driver box.

Step 9: STANDARD CEILING: Install downlight insert to ceiling
SCA CEILING: Install downlight insert to sloped ceiling trim
A. STANDARD CEILING: Maneuver the downlight insert up
through the ceiling cutout until the stop tabs are flush
against the ceiling plane.
SCA CEILING: Maneuver the downlight insert up through the
sloped ceiling trim until the stop tabs are flush against the
lower stop ring.
B. While continuing to support the insert, use a 9/64” hex bit to
drive the (3) installation screws - this will cause the swing-
out arms to deploy, draw down, and clamp the insert in
place. (see FIGURES 9.1 & 9.2)
