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”.

two O-Ring between dome and lower cover (Figure 23 - n°2 and 3);
