6.2.2 Check the light fixture for water-tightness
If maintenance is carried out in a workshop, check the water-tightness of the light.
Prepare
1. Remove the water-tightness test valve cap.
2. Fill up the light fixture with compressed air (test pressure = 130 kPa).
Test
1. Put the light fixture in water, wait 3 minutes and check if air leaks out of the light.
a. If air leaks out of the light fixture (between bottom cover and top plate or between prism and top plate or water-
tightness valve and top plate), the light fixture is not watertight and must be repaired. Release the air from the light.
Disassemble the light fixture and re-check the mating surfaces and gaskets. Assemble the light fixture and perform the
water-tightness test again.
b. If the light fixture is water tight, release the compressed air from the light fixture and assemble the cap on the test
valve.
2. The light fixture is ready to be reinstalled in the field.
DANGER
Never exceed pressure of 150 kPa inside the light fixture as this may lead to personal injuries and damage the light.
