Maintenance Program

In order to insure maximum light fixture life, the installed units should be subject to a
maintenance program in accordance with the following: A daily operation check should be
made of the lighting fixture. The lights should be energized and visually inspected. If any
fixtures are out, the location of the fixture should be recorded and the lamps replaced at a time
when the circuit is de-energized. (See Section 9.2)
9.8.1 Regular cleaning is necessary in order to insure that inset lighting fixtures operate at
maximum efficiency. The lens should be cleaned periodically with a soft cloth and solvent.
The weather and the location of the fixtures will dictate the regularity and type of cleaning.
9.8.2 Snowplow operators should exercise extra care not to strike the light fixtures with snowplow
blades (use rubber blades for added protection to the fixture.) After snowplow removal
operations, inspect all light fixtures to locate and replace if necessary, any damaged Light
Assemblies. Passes over the light rows should be made with a power broom only if practical.
Whenever snowplows must traverse in-pavement light fixtures, they should be traveling at
less than 5 mph or have the blades lifted clear of the fixture.
9.8.3 The light is designed to exclude both ground and surface water from entering. If the lights are
not properly maintained (i.e., bolts tightened and seals in good condition) water may enter the
fixture. To prevent this from occurring, it is recommended that each fixture be inspected for
the presence of water at least once a month. More frequent inspection is desirable during and
following rainy seasons
9.8.4 FAA approach fixtures hold-down bolts shall be checked for proper torque per Section 8.1
9.8.5 If any fixture contains water, the water should be removed and the entire fixture cleaned and
dried. Perform a pressure test per paragraph 9.6 to locate the source of the leak. Replace the
o-ring (21385), see Section 9.3.
