10.10 Pressure Test
A light unit should be subjected to a 20-psi maximum 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 underside of the inner cover. Pressurize the light unit to 20-psi using a regulated/controlled
air source, 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 light unit or attempting to repair a leak.
WARNING
WARNING:
Do not exceed 20-psi when pressure testing the light unit. Serious injury
and/or permanent damage to the light unit may result if a higher air pressure
is used. Once the pressure test is complete, be sure to relieve the air
pressure.
