INSTALLATION
a)
Take as reference Figure 7 for spacing between breakable couplings.
b)
Remove the sign from the relevant packing.
c)
The signs are normally installed so that the cable entry is located toward the runway or taxiway
edge.
d)
The concrete foundation for the sign should be flat and levelled. Refer to Figure 9 for relevant
data. The isolating transformer must be placed inside a concrete pit complete with pipe elbow
for the secondary cable passage or inside a steel base complete.
e)
It is recommended that the anchor bolts (M12X60) used for the flange anchoring, are mounted
after the completion of the concrete foundation. The anchor bolts have to be walled accurately
as shown in Figure 9 and in manner to assure the parallelism of the centreline marked on the
flange and the sign centreline.

f)
Remove the frangible couplings/floor flanges from the bottom of the sign by loosening the
locking screws (set screw M8x14).
g)
Taking care of the levelling of the floor flanges is very important to ease the installation of the
sign. Place a long carpenter level across the top of the breakable couplings to verify their
