INSTALLATION
The fixture is normally installed on level ground, at the edges of the runway, on a 12” FAA L-867
base, that will be used to house the transformer, and a base plate. Please refer to FAA
instructions provided in AC 150/5340-30 and ICAO Annex 14, vol. I.
Figure 3 - Installation on FAA L-867 base plate and base plate
Assuming that the L-867 base has been correctly installed, install fixture and base plate (fig.3) as
follows:
•
Thread the fixture connector through U-shaped frame, frangible coupling and locking ring;
ensure to screw the locking ring all the way up to the edge of frangible coupling thread.
•
Connect fixture connector to the receptacle in the top section of the base plate
•
Screw the frangible coupling onto the threaded section of the base plate. Apply anti-seize
grease first and do not tighten yet.
•
Orient the row of holes in the frangible coupling in the same direction as the light beam
(horizontally) and tighten the locking ring fully onto the base plate.
•
Insert the fixture with the U-shaped frame on the frangible coupling and insert the
alignment pin through the holes. Do not tighten the two rear retaining screws of the U-
shaped support frame.
•
Orient the fixture (see section 5).
