How to mount the light assembly?
Make sure that the contact surfaces of the light assembly with base or adapter ring
and the gaskets are absolutely clean and smooth.
Please refer to the paragraph, page 8: only use fixing hardware of the same type
as the one originally supplied with the base or adapter ring!
In ADB shallow bases delivered since mid-2006, the type of thread is indicated on
the bottom or the flange of the base: METRIC M10 or 3/8”-16UNC .
How to be sure of the type of fixing hardware you are using?
- M10 screws require the use of a 17mm socket.
- 3/8"-16UNC screws require a 9/16" socket, this is approximately
14.3mm.
On a base or adapter ring with metric M10 female thread, never use a screw that
can be fastened with a socket smaller than 17mm: it would indicate that you are
inserting a 3/8"-16UNC screw in a M10 female thread.
The opposite -inserting a M10 screw in a 3/8"-16UNC female thread- is impossible.
To mount and connect the light assembly, proceed as follows:
Step Action
1
In case a light has already been mounted on the base, remnants of
Loctite are present in the fixation holes. 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.
2
If the labyrinth gasket (F11) is not installed, put a new, clean one in the
dedicated groove at the cover periphery
CAUTION: Never re-use an already used gasket.
