Maintaining the SIFZ ILS
Maintaining the SIFZ ILS
PERIODICALLY CHECK THE GLASS: The effectiveness of the ILS light bar
depends on the clarity of the glass it is being placed behind. Dirt and defects
in the glass reduces the light output. The reliability of light for emergency
signaling purposes may be reduced if the glass is dirty, cracked, or not clear.
Be sure to periodically check the glass for cleanliness to ensure maximum
light output of the light bar.
Establishing a regular maintenance schedule for the ILS light bar extends its life and
ensures safety. Periodically check that the light bar operates properly and that all
mounting hardware is securely fastened to the vehicle. Inspect the reflectors for cracks,
crazing (hairline cracks), discoloration, and other defects.
Cleaning the Shrouds
To clean the shrouds:
1.
Remove the light bar from the vehicle according to the vehicle-specific installation
instructions included with the ILS light bar.
2.
Use a soft tissue to clean the shroud. If needed, you can use a solution of mild
soap and water, but take care not to get water on the PCBs.
3.
When finished, make sure the light bar is completely dry before reinstalling it
according the vehicle-specific installation instructions.
Cleaning the Domes
Periodically cleaning the domes using proper procedures and compatible cleaners will
prolong their service life.
CRAZING HAZARD: Crazed, cracked, or faded domes or reflectors reduce the
light output and the effectiveness of the lighting system. Tops or reflectors
showing this type of aging must be replaced. Failure to follow this warning
may result in bodily injury or death to you or others.
CLEANING SOLUTION WARNING: The use of cleaning solutions, such as
strong detergents, solvents, and petroleum products, can cause crazing
(cracking) of the domes and reflectors. Failure to follow this warning can
damage the domes and reflectors and may result in bodily injury or death to
you or others.
