FIRE RATED LED 4" NEW
TM
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 (Fig.11). 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

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.
