Gasket examination
Every time a fixture is opened each O-Ring must be examined as described below and
replaced if necessary.
Any O-Ring that is stretched, torn, has a permanent set or some other defect, which
would prevent it from obtaining a water-tight seal must be replaced with a new O-
Ring.
Remove the fixture from the base and open it following instructions of
“Removing
and Opening the Light Unit From the Base”
.
Light assembly is equipped with the following gaskets:
O-Ring between dome and lower cover (Figure 1- n°20);
O-Ring around the dome (Figure 13 - n°1);
O-Ring between fixture and 12” shallow base (Figure 13 - n°3);
