The Juno Slimform LED downlight is designed for installation in UL-listed junction boxes. Before beginning, ensure the power is turned off at the circuit breaker. The fixture features an adjustable color temperature switch on the back and requires specific arrow alignment for secure installation.
Important Safety Information
- Installation and service must be performed by a qualified licensed electrician.
- Disconnect power before installation or servicing.
- Ensure the junction box is properly grounded.
- Do not install damaged products.
- The fixture is suitable for damp locations; wet locations require sealing with silicone caulk.
Installation Steps
- Preparation: Verify all parts are included: LED module, mounting bracket, wirenuts, screws, and nut.
- Color Temperature: Move the switch on the back of the fixture to the desired color temperature setting before installation.
- Mounting Bracket: Secure the mounting bracket to the junction box using the provided #8 screws. Ensure the side labeled "THIS SIDE DOWN" faces the floor. For square fixtures, align the straight edge of the bracket parallel to the wall.
- Tether Cable: Attach the tether cable eyelet using the 12mm screw (Method A) or by securing it under one of the mounting screws (Method B).
- Wiring: Connect the bare copper ground wire from the fixture to the junction box ground wire. Connect the black fixture wire to the black power supply wire and the white fixture wire to the white power supply wire using wirenuts.
- Final Assembly: Position wires into the outlet box. Align the straight arrow on the mounting puck with the straight arrow on the mounting bracket. Twist the fixture clockwise while pushing upwards until you feel a "bump" to lock it in place.
Wiring and Dimming
For fixtures with 0-10V dimming (120-277V drivers), connect the violet dimmer wire (+) to the positive dimmer wire and the pink dimmer wire (-) to the negative dimmer wire. Ensure all connections are capped with UL-approved wire connectors.
Troubleshooting
If the fixture fails to operate:
- Verify that the fixture is wired properly.
- Ensure the fixture is grounded correctly.
