Installing the lens

the lens into place.

Cleaning the Glass Lens and Reflector
Replace the lens if it contains visible damage such as cracks or deep scratches that may impair its
effectiveness.
The reflector is located behind the lamp. You must remove the lamp before cleaning the reflector.
Remove 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 both to clean the lens and reflector.
Note:
Do not leave fingerprints on the lens. Handle the lens with a soft, clean cloth.
Note:
The lens will not fit properly and will not function correctly if it is installed with the
stepped side facing the rear of the fixture.
WARNING:
Do not use ammonia-based or other harsh commercial cleaners. Clean lens
only as directed.
Commercially available glass cleaning agents should be avoided because 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.
