4. Setup and Installation
Before You Begin:
- Turn off power at the circuit breaker or fuse box.
- Ensure you have the necessary tools: screwdriver, wire strippers, electrical tape, and safety glasses.
- Confirm that the compatible new construction housing (HR-2LED-H13A or HR-2LED-H13AC) is already installed.
Step-by-Step Installation:
- Prepare the Housing: Ensure the power to the recessed housing is off. Remove any existing trim or components from the housing.
- Connect Wiring: Locate the wiring connector from the LED light engine. Connect it to the corresponding connector inside the recessed housing. Ensure a secure connection.
- Insert Trim: Carefully push the Aether 2in Round Light Engine Trim into the recessed housing. The spring clips on the trim will engage with the housing to hold it securely in place. Apply gentle, even pressure until the trim is flush with the ceiling surface.
- Secure Trim: For some installations, additional mounting hardware may be used to further secure the trim. Refer to the specific instructions provided with your housing for details.
- Restore Power: Once the trim is securely installed, restore power at the circuit breaker.
- Test Functionality: Turn on the light switch to verify proper operation and dimming capabilities.

5. Operating Instructions
Standard Operation:
Once installed and power is restored, the Aether LED trim operates like any standard light fixture. Use your wall switch to turn the light on or off.
Dimming Functionality:
This fixture is designed for smooth and continuous dimming down to 1% when used with compatible Electronic Low Voltage (ELV) or 0-10V dimmers. Ensure your dimmer switch is compatible with LED lighting and specifically with ELV or 0-10V systems for optimal performance. Refer to your dimmer's instruction manual for specific operating procedures.
6. Maintenance
The WAC Lighting Aether LED trim requires minimal maintenance.
- Cleaning: To clean the fixture, ensure power is off. Use a soft, dry, or slightly damp cloth. Do not use abrasive cleaners or solvents, as these may damage the finish or electrical components.
- LED Light Engine: The LED light engine is replaceable. If replacement is necessary, ensure power is off and follow the reverse of the installation steps to remove the old engine and install a new, compatible WAC Lighting LED light engine.
- Inspection: Periodically inspect the fixture for any signs of damage or loose connections. If any issues are found, disconnect power and consult a qualified electrician or WAC Lighting customer support.
