Clean the Lens and the Fixture Housing

Clean the lens and the heat-dissipating fins on the fixture housing at least once a year to ensure optimum performance. You may need to clean more often, depending on the type of fixture use and amount of fixture use.

WARNING: Note the following safety warnings before cleaning:

  • Allow fixture to cool completely before you clean.
  • Disconnect all power and DMX cables before you clean.
  • Do not spray liquids into the fixture.
  1. Remove the shutter barrel and lens tube (A) by removing the screw (B) and the barrel rotation knob (C), and then separate the fixture and shutter barrel.
  2. Use a clean micro-fiber cloth to clean the lens. You can use isopropyl alcohol on the cloth. However, do not spray the cleaning solution directly onto the lens or the interior of the fixture.
  3. Reinstall the shutter barrel and lens tube, and secure with the retaining bolt and the barrel rotation knob.
  4. Clean the four sets of heat-dissipating fins on the fixture enclosure (D) using a soft cloth or compressed air.
