Setup and Installation

Installation of the Solatube Light Add-On Kit requires access to your existing Solatube system's ceiling fixture. It is recommended that installation be performed by a qualified professional or an individual with experience in electrical and ceiling work.

  1. Safety First: Ensure power to the circuit where the Solatube is installed is turned off at the main breaker before beginning any work.
  2. Access the Fixture: Carefully remove the existing diffuser from your Solatube ceiling fixture to expose the interior.
  3. Mount the Light Kit: Follow the specific instructions provided with your kit to securely mount the light add-on assembly within the Solatube fixture. This typically involves attaching it to designated points within the tube.
  4. Electrical Connection: Connect the electrical wiring of the add-on kit to your home's electrical system. This step is crucial and should only be performed by a qualified electrician if you are not comfortable with electrical work. Ensure all connections are secure and comply with local electrical codes.
  5. Install Bulbs: Screw in the appropriate E26 medium base bulbs (not included) into the sockets.
  6. Reinstall Diffuser: Carefully reattach the Solatube diffuser to the ceiling fixture.
  7. Test Functionality: Restore power at the main breaker and test both the daylighting and electric lighting functions.

Operating Instructions

The Solatube Light Add-On Kit operates in conjunction with your existing Solatube system. During daylight hours, the system will provide natural illumination. For nighttime use, the integrated electric light can be activated.

  • Daylight Operation: The Solatube system will automatically provide natural light whenever sunlight is available. No manual operation is required for daylighting.
  • Nighttime Electric Light: The electric light component of the add-on kit is typically controlled by a standard wall switch (not included, wired during installation). Flip the switch to turn the electric light on or off as needed.

Maintenance

The Solatube Light Add-On Kit is designed for minimal maintenance. Regular cleaning of the ceiling diffuser is generally sufficient to maintain optimal light output.

  • Diffuser Cleaning: Periodically remove the ceiling diffuser and clean it with a soft, damp cloth and mild soap. Ensure it is completely dry before reinstallation.
  • Bulb Replacement: If an electric bulb burns out, ensure the power is off at the breaker before carefully removing the old bulb and screwing in a new E26 medium base bulb of the appropriate wattage.
  • Exterior Components: The exterior dome and flashing of your Solatube system are designed to be weather-resistant and typically require no maintenance. If debris accumulates, it can be carefully removed from the roof level.
