3INSTALLATION
3.1 CIVIL WORKS
Each light is usually installed on a suitable concrete block, into which a pipe elbows is
cemented. The isolating transformer is housed into a separate concrete pit which is
normally placed close the above concrete block (Figure 4).
The pit can be placed far from the concrete block too, but in this case a suitable cable
duct has to be provided between the pit and the pipe elbow for passing the
secondary cable.
As alternative the assembly pit-pipe elbow can be replaced by a steel sheet base,
which can be used to house the isolating transformer, complete with an upper steel
plate with a threaded sleeve.

INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
3.2 INSTALLING THE LIGH UNIT
The light is shipped completely assembled including the LED module, except the 1-
inch tube and the breakable coupling which are delivered separately inside the same
carton.
Note: if the fixture has been ordered with an extra height option, the tubing may be
packaged separately.
For the installation of the light the following steps are suggested:
pass together the secondary cable lead with receptacle and a suitable length of
grounding wire (grounded inside the pit) through the pipe elbow
place the receptacle into the upper threaded section of the pipe elbow, by
holding it between the two plastic rings, and pass the grounding wire through the
rings (in correspondence of break point provided on the rings)
slide one end of the 1-inch tube over the fixture cable assembly (cable leads with
plug plus yellow-green wire) and into the fixture body until the body bottoms
against the tube
approach, without tighten, the set screws on the side of the body to the 1-inch
tube
slide the frangible coupling over the cable assembly (cable leads with plug plus
yellow-green wire) and onto the other end of the 1-inch tube until it bottoms
against the tube
connect the fixture grounding wire to the grounding wire coming from the pit (or
from the base): splice both the wires and connect them together by using a
crimping connector
connect the light plug to the secondary receptacle inside the pipe elbow
slide the frangible coupling down over the plug and tighten it into pipe elbow (or
the base plate) until coupling bottoms out. Push any extra cable length into the 1-
inch tube. Tighten the tube to the coupling with the setscrew on the coupling
Place on the lens locking ring the levelling device (P/N 332.3500 available on
request) as shown in Figure 5. Levelling the light body by operating the three
levelling screws until the bubble is centered
remove the levelling device

4MAINTENANCE
WARNING
BEFORE ANY MAINTENANCE INTERVENTION, MAKE SURE
THE POWER SUPPLY BE SWITCHED OFF.
DO NOT OPERATE ON LIVE PARTS!!!
LED lighting fixtures do not require frequent maintenance. With well-run installations
and handling fixture carefully, avoiding excessive falls or collisions, the only
maintenance work to be carried out on the field is to clean the prisms.
4.1 MAINTENANCE PROGRAM
In order to ensure maximum light fixture life, the installed units should be subject to
a maintenance program in accordance with the following instructions and taking as
reference the Airport Service Manual ICAO - Part 9 - Airport Maintenance Practices or
FAA AC 150 5340-30.
