Instruction Manual

Aculux residential fixtures
equipped with the patented
Pro-VI™ hanger bar system are
designed to fit in common joist
spacings up to 24” on center,
and are compatible with various
construction materials such as
dimensional lumber, engineered
lumber, and steel studs.
The Pro-VI™ hanger bar feet also include additional
fastener holes for mounting in special applications where
the pre-installed nail location is not compatible.
1. Position fixture between joists, and slide towards the first
joist. (Note: Square and round housings include integral
v-notch markings on plaster frame return to assist in
locating fixtures.) (Fig. 3)
2. Align the flanges on hanger bar feet with the bottom of the
joist, ensuring that the flanges are flat and parallel with
the bottom of joist.
3. Drive nails securely into the first joist.
4. Slide the fixture along the telescoping bars towards the
second joist, ensuring the bars remain perpendicular to
the joists.
5. Repeat steps 2 and 3 to secure.
6. Slide fixture to the desired position on the hanger bars,
and tighten the screws on the bar guides to lock in place.
WARNING: For your safety, read and understand instructions completely before starting installation. Before wiring to power supply, turn off electricity at fuse or circuit breaker box.
NOTE: Aculux recessed fixtures are designed to meet the latest NEC requirements and are listed in full compliance with the relevant UL standards. Before attempting installation of any recessed lighting fixture, check your local electrical building code. This code sets
the wiring and installation requirements for your locality and should be understood before starting your work. Use of Non Aculux trims voids warranty.
INSTALLATION INSTRUCTIONS FOR ACULUX LED 3 1/4˝ RECESSED HOUSING
WITH BLACK BODY DIMMING AND TUNABLE WHITE LED TECHNOLOGY
TYPE TC for Non-Insulated Ceilings
TYPE IC for Insulated Ceilings
Installation into Joist Construction
Aculux “TC” fixtures (type non-IC) are designed for installations
where the housing and J-Box will not come into contact with
insulation*. Insulation must be spaced at least 3” away from the
housing and J-Box. Blinking or powering off of the light during
use indicates an overheating condition which may be caused by
insulating material being too close to or covering fixture.
Caution: Failure to correct an overheating condition may result
in fire and serious injury.
*In Canada, when insulation is present, Type IC fixtures must
be used.

Aculux IC and Non-IC recessed housings meet energy code air
leakage requirements per ASTM E283. This stops infiltration
and exfiltration of air, which contributes to reduced heating
and cooling costs.
Aculux type IC fixtures are designed for direct contact with
insulating materials approved for the application. They may also
be used in non-insulated ceilings.
Shortening Pro-VI™ Bars
Installation into Suspended T-bar Grid Ceilings
Aculux fixtures contain either the patented Pro-VI™ hanger bar
systems or standard butterfly-style mounting brackets, which
both provide secure mounting in suspended T-bar ceilings.
The Pro-VI™ hanger bar system mounts to T-Bars spaced
on 24” centers and the butterfly-style mounting brackets can
accommodate 1/2” EMT, 3/4” & 1-1/2” C-channel, and linear bars.
To mount the Aculux Pro-VI™ hanger bar system to
T-Bar ceilings:
1. Determine the desired position for the fixture and cut
a hole in the ceiling tile according to the recommended
cut-out dimensions.
2. Fully expand the bars of the Pro-VI™ hanger bar system
until the stop is reached.
3. Position the fixture in the ceiling tile opening and clip the
four hanger bar feet over the T-bar.
4. Lock each hanger bar foot to the T-bar using the two
integral locks or a sheet metal screw (supplied by others).
If tie-wire is desired for additional support, each bar hanger
foot has holes suitable attachment of wire. (Fig. 5A)
5. Tighten the set screws on the hanger bar guides to lock
the bar position.
6. If desired, bend the break-away flange on the hanger bar
foot to snap off. This can prevent interference with adjacent
ceiling tiles. (Fig. 5B)
To mount Aculux fixture using butterfly-style mounting brackets:
1. Determine the desired position for the fixture and cut a
hole in the ceiling tile according to the recommended
cut-out dimensions.
2. Pass the EMT, C-channel, or linear bars through the
openings in the butterfly style bracket.
3. Position fixture in the ceiling tile opening. Adjust butterfly
brackets to the desired height using the wing nuts located
on the bracket. When desired height is reached, tighten
wing nuts to lock.
4. Secure mounting bars to corresponding structure.

Electrical Connection Instructions
Fig. 6
All Aculux fixtures contain an integral junction box that allows
both connection of power to the fixture and passing additional
conductors through the junction box. Type IC fixtures are UL
listed for (4) through branch circuit conductors rated at 90°C,
and type Non-IC (TC) are UL listed for (8) through branch circuit
conductors rated at 90°C.
All Aculux housings also come pre-wired with UL Listed push-in
style wire connectors for connection of the branch circuit supply
and ground conductors to the fixture. These push-in wire
connectors allow up to two 12AWG or 14AWG solid copper wires
to be connected to each fixture lead and ground.
1. Provide electrical service according to your local electrical
code to the Aculux junction box located on the plaster frame.
Supply wire insulation must be rated for at least 90°C.
2. Remove the junction box cover and attach the electrical
service as follows: (Fig. 6)
a. Metal conduit: Remove appropriate round
knock-out(s) and connect conduit to junction box
with proper fittings (supplied by others).
b. 12/2 or 14/2 non-metallic sheathed cable (type NM-B):
Remove appropriate knock-out(s) from top of junction
box and insert cable, pushing it past the cable grip
(Additional connectors are not required).
c. 12/3 or 14/3 non-metallic sheathed cable (type NM-B):
Remove appropriate round knockout(s) and connect cable
to junction box with proper fittings (supplied by others).
3. Strip 3/8” insulation from the branch-circuit supply and
ground wires, and insert into the corresponding push-in wire
connector as shown in the corresponding wiring diagram.
4. Place all wiring and connections in junction box and
replace cover.

Knock-outs for Non-Metallic Cable
Knock-outs for Metal Conduit
Aculux recessed housings with Black Body Dimming and
Tunable White technology are controllable with standard
0-10VDC current sinking protocol or DMX512 protocol.
Note: For DMX512 Control it is recommended that these
connections are made by a low voltage wiring specialist.
Reference Aculux DMX Installation Guide P6160.
0-10V Control (-ZT, -ZT, -ZT) – This requires switched input
power with separate low voltage control wires. Fixtures can
be controlled with (1) or (2) sets of control wires in one of the
following ways:
1. Black Body Dimming – Uses violet & pink(or gray)
control wires (yellow & blue capped off).
Fixture shifts color temperature from 3000K to <1800K as
fixture is dimmed to 1% output, mimicking a traditional
halogen source.
In some applications, mounting
the Aculux fixture in joist spans
smaller than 16” on center is
desired. The Pro-VI™ hanger
bar system allows tool-less field
shortening to fit within a 9-1/4”
wide opening for type non-IC
fixtures (TC) and a 10-3/4” wide
opening on type IC fixtures.
To field shorten:
1. Remove telescoping bars from the fixture by extending to
the maximum length and pulling apart (past the stop)
2. Locate the notch in the bar furthest from the foot.
3. Grip bar on both sides of this notch, and bend the bar in the
direction opposite the notch. As this notch spreads open,
the bar will break along the score line. (Fig. 4)
4. Repeat step 3 on the other bar.
5. Reinstall bars into the guides on the fixture.
