How to close and test the light fixture
To close an optical unit, proceed as follows:
Step Action
1
Turn the cover (B1) upside down. In order for the cover to rest on a
stable surface it is advised to lay it upside down on the top of a shallow
base.
2
Make sure that the contact surfaces with the O-ring are clean.
Remnants of Loctite may be present in the fixation holes of the screws
F4. Clean them using a cleaning tap for blind holes (preferably use a tap
with a right spiral groove) and blow with dry, oil-free compressed air.
3 Put a new O-ring gasket (B8) greased with high quality neutral silicone
grease (ADB PN 7850.42.210) over the cover in the appropriate groove.
4
Remove the pressure release screw (F9).
