Clean the Lenses
WARNING:
Do not use ammonia-based or other harsh
commercial cleaners. Clean lens and reflector only as directed.
Commercially available glass cleaning agents should be
avoided as they may contain ammonia, other harsh chemical
detergents or abrasive agents. These cleaners may damage
the glass surface and the Anti-Reflective coatings. Do not
immerse or soak the glass in any cleaning solution.
Note:
To clean the inside of lenses, you must remove the lenses
from the lens tube. For instructions on removing the lenses, see
the Source Four Assembly Guide, which is available for download
at
Replace lenses if they contain visible damage (cracks or deep scratches)
that may impair their effectiveness.
1. Remove the lens tube from the fixture barrel:
a. Remove the beam focus knob and retaining bolt from the top
of the barrel and set aside.
b. Slide the lens tube out of the barrel.
2. Remove any dust with a blast of oil-free air or wipe with a clean,
lint-free cloth. You can use isopropyl alcohol, distilled water, or a
50%-50% mixture of each to clean the glass surface.
3. Slide the lens tube back into the barrel with the color frame
retaining clip on top. Reinstall the beam focus knob and retaining
bolt.
