CLEANING POLYCARBONATE DOMES AND LENSES: Crazing
(fine cracks) of lenses causes reduced effectiveness of the light.
Do not use cleaning agents (which causes crazing) such as
strong detergents, solvents, or petroleum products. If crazing
of lenses does occur, reliability of light for emergency signaling
purposes may be reduced until lenses are replaced.
CLEANING POLYCARBONATE DOMES AND LENSES: To extend
the life of this device, periodic cleaning is necessary. Clean the
lens/dome with a mild, non-abrasive, neutral-pH cleaning agent
and a soft, clean cloth. Rinse the device thoroughly to ensure
that no cleaning agent residue remains. To avoid water spots,
dry the device with a soft clean cloth.
Failure to follow this precaution can cause crazing or cracking of
the lens/dome and voids the warranty claims for the light.
NOTE:
Scratched or dull reflectors, mirror, or lenses reduce the
effectiveness of the lighting system. Use a mild, non-abrasive,
neutral-pH cleaning agent and a soft, clean cloth, when cleaning
the lighting system. Replace any optical components that may
have been scratched or crazed during system installation. The
use of strong, non-neutral-pH cleaners voids the warranty.
