INSTALLATION INSTRUCTIONS

JUNO IC1LED NEW CONSTRUCTION
RECESSED HOUSINGS

WARNING: For your safety, read and understand instructions completely before starting installation.

Before wiring to power supply, turn off electricity at the fuse or circuit breaker box.
NOTE: Juno recessed fixtures are designed to meet the latest NEC requirements and are listed in full compliance with the
relevant UL standard(s). Before attempting installation of any recessed lighting fixture, check your local electrical building
code. This code sets the wiring standards and installation requirements for your locality and should be understood before
starting work. Use of non-Juno trims voids Juno warranty.

TYPE IC FOR
INSULATED CEILINGS

Figure 1

Juno Type IC fixtures are designed for direct
contact with insulating materials which are
approved for this application (Fig. 1). Fixtures
may also be used in non-insulated ceilings.

Juno Air-Loc LED housings are supplied
with pre-installed gaskets for energy savings
and to comply with energy code air leakage
requirements per ASTM E283.

INSTALLATION INTO
JOIST CONSTRUCTION

Step 2. Slide fixture along bar hangers into

desired location. Use locking screws or slot to
secure (Fig. 4).

Relocating Fixture – Nail can be removed
with hammer claw to allow easy repositioning
of fixture without damaging bar hanger or nail
(Fig. 5).

Step 3. Follow steps 1-4 under Electrical
Connection.

Step 4. When installing in drywall, cut a hole
measuring 4-1/2” diameter. After installing
drywall, adjust inner housing height
(if necessary) to match the bottom surface
of ceiling by pulling down on inner housing,
which is retained by springs. The housing is
adjustable for ceilings up to 1-1/2” thick.

INSTALLATION INTO
SUSPENDED CEILING

Figure 6

Step 1. Locate center of proposed opening

on ceiling tile and cut a hole measuring
4-1/2” diameter.

Step 2. Place ceiling tile in T-bar grid.

Step 3. Place fixture into position and snap

bar hanger foot with integral T-bar notch onto
T-bars (Fig. 6). Additional holes are provided for
securing with wire or screws if desired (Fig. 7).

Step 4. Follow Steps 1-4 under Electrical
Connection.

Figure 2

Step 1. Extend bar hangers to fit between

joists. Bar hanger foot is contoured to easily
align with bottom of joist (Fig. 2). Position fixture
by hammering Real-Nails® into joists (Fig. 3).

(Note: Bar hanger may be shortened to fit 12”
framing or smaller by breaking at score lines).

Step 1. Provide electrical service according to

national and/or local electrical code to the wiring
box located on the fixture plaster frame. Supply wire
insulation must be rated for at least 90°C.

Step 2. Remove wiring box cover. Remove the
appropriate knock-out(s) to accommodate the type
of electrical supply being used (Fig. 8):

Metal Conduit. Remove appropriate round knock­out(s) and connect conduit to wiring box with proper
connectors (not supplied).

12/2 or 14/2 Non-Metallic Sheathed Cable
(Type NM-B). Remove appropriate D-shaped cable

knock-out(s). Insert the NM-B cable through the
cable trap and make a 90˚L-shaped bend in cable
as shown (Fig. 9).

12/3 or 14/3 Cable (Type NM-B). Remove the
appropriate round knockouts and connect cable
with proper electrical connectors (not supplied and
not shown).

Step 3. Strip supply wire 3/8” and insert each supply
wire into appropriate connector. Connect black fixture
wire to hot, white fixture wire to neutral and green
fixture wire to ground. (Fig. 8).

Connect violet (+) and gray (-) dimmer wires,
( -U models only).

FIXTURE DIMMING

Universal Voltage IC1LED Downlights:
Universal input voltage (120VAC thru 277VAC)
housings. Dimmable with the use of most 0-10V
wall box dimmers.

120VAC IC1LED Downlights: 120VAC input
housings. Dimmable with the use of most
incandescent, magnetic low voltage or electronic
low voltage* wall box dimmers.

Consult Juno Product Services or website
for compatibility.

*Electronic low voltage dimmers require a neutral
wire connection in the wall box.

TRIM INSTALLATION

After ceiling is finished and painted, remove
and discard paint shield from fixture.
Insert trim into fixture by lining up trim springs
with the housing opening, and pressing trim up
towards the ceiling. Take note of the position of
the optic within the housing, and avoid contact
with it when pushing in trim.

DRIVER REPLACEMENT

Driver replacement must be performed by
a qualified electrician. Before servicing,
disconnect or switch off electrical supply to
fixture. Failure to do so can result in electrical
shock and/or injury.

120VAC IC1LED Downlights:

Step 1. Remove trim from fixture.

Step 2. Pull down inner housing to remove

from fixture. Disconnect red and black wires
connecting driver to inner housing and set
aside. (Fig. 10)

Step 3. Remove junction box cover and
disconnect driver lead wires from supply
connections.

Step 4. Loosen wing nuts and slide driver out
of the mounting bracket. Remove from housing.
(Fig. 11)

Step 5. Install new driver into mounting bracket
and tighten wing nuts to secure in place.

Step 6. Re-connect all leads disconnected in
prior steps.

Step 7. Re-install
inner housing and
trim by pushing up
into housing.

Universal Voltage
IC1LED Downlights:
Step 1. Remove
trim from fixture.

Step 2. Pull down
inner housing to
remove from
fixture. (Fig. 10)

Step 3. Remove the wing nuts holding the
driver to the housing. Bring driver (with leads
connected) through ceiling opening. (Fig. 11)

Step 4. Release all wires from driver by using
the quick disconnect slots located next to each
wire.

Step 5. Insert wires into the ports on the new
driver. Note: The red LED lead goes into the
black opening and the black LED lead goes into
the yellow opening on the secondary side.
