9.6 Pressure Test

A light fixture should be subjected to a 20-psi air pressure test to verify that it is waterproof
whenever it has been opened or components have been replaced. A tire valve style pressure fitting
is located on the bottom of the inner cover. Pressurize the fixture to 20-psi then place it in a tub of
water or use a soap solution to locate escaping air bubbles. Carefully inspect the areas around the
lens, inner cover seal, and feed-thru adapter for leaks. Relieve the internal air pressure before
installing the fixture or attempting to repair a leak.
Note –
and/or permanent damage to the fixture may result if a higher air pressure is
used. Once the pressure test is complete be sure to relieve the air pressure.
9.7 Cleanliness and Workmanship
Service life depends upon the entire assembly being waterproof. All surfaces must be clean, dry and free
of all foreign matter if the light fixture is to operate for extended periods without requiring maintenance.
9.8

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 lamps 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 and channel in front of 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.
Snowplow operators should exercise extra care not to strike the light fixtures with snowplow
9.8.2
blades. 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 fixtures.
The light is designed to exclude both ground and surface water from entering. If the lights are
9.8.3
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.
