SAFETY INSTRUCTION

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.
When installed according to the instructions provided and as specified in the UL Fire Resistance Directory, Juno IC1LEDFW luminaire may be used in fire resistance Floor-Ceiling and Roof-Ceiling designs. See UL Fire Classified Directories CDHW and CDHW7.
NOTE: Use of Non-Juno trims voids Juno warranty.

TYPE IC FOR INSULATED CEILINGS

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 preinstalled gaskets for energy savings and to comply
with energy code air leakage requirements per ASTM E283.

INSTALLATION INTO JOIST CONSTRUCTION

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 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.

ELECTRICAL CONNECTION INSTRUCTIONS

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.6):

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 knockout( s). Insert the NM-B cable through the cable trap and make a 90˚L-shaped bend in cable as shown (Fig.7).

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. 6).
Connect violet (+) and gray (-) dimmer wires, if utilizing 0-10V dimmer.
Step 4. Place all wiring and connectors back in wiring box and replace cover

TRIM INSTALLATION

After ceiling is finished a:nd 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.

FIXTURE DIMMING

Multi-Volt LED 4″ Downlights:
Universal input voltage (120VAC thru 277VAC) housings.
Dimmable with the use of most 0-10V wall box dimmers.
120VAC LED 4″ 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.
WARMDIM™ is 120VAC only.
Electronic low voltage dimmers require a neutral wire connection in the wall box.

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.

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.8)
Step 3. Now access the fixtures wiring by carefully pulling it through the opening. Once exposed you can proceed with disconnecting the AC leads that provide power to the driver and any applicable dimming wires.
Step 4. Lift fire barrier flap on the side with the red and black wires protruding (red and black wires indicate driver location). The bottom of the flap will have a half moon finger slot for easy lifting (Fig.9). Before lifting the flap, make sure the wires are pushed out of the wire slots provided in the flap to prevent tearing the fire barrier (Fig.10). This will allow access to the LED driver.
Step 5. Remove wing nut from driver plate to remove driver plate from fixture (Fig11). Pull driver plate out while slightly lifting to release lower mounting feet. Once free, pull plate towards fixture opening and rotate plate 90° so it will fit through fixture opening. Driver plate rubbing against fire barrier is acceptable.
Step 6. Re-assemble fixture by completing steps 1 thru 5 in reverse order.

JUNCTION BOX ACCESS

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. 8).
Step 3. Now access the fixtures wiring by carefully pulling it through the opening. Once exposed you can proceed with disconnecting the AC leads that provide power to the driver and any applicable dimming wires.
Step 4. Lift fire barrier flap on the side with the red and black wires protruding (red and black wires indicate driver location). The bottom of the flap will have a half moon finger slot for easy lifting (Fig. 9). Before lifting the flap, make sure the wires are pushed out of the wire slots provided in the flap to prevent tearing the fire barrier (Fig. 10). This will allow access to the LED driver.
Step 5. Open junction box door inside of fixture by lifting black spring retention clip. Once junction box door is released pull door out while slightly lifting to release lower mounting feet. Once free pull plate towards fixture opening and rotate plate 90° so it will fit through fixture opening. Junction box door rubbing against fire barrier is acceptable.
Step 6. Re-assemble fixture by completing steps 1 thru 5 in reverse order.
