LED ELEVATED HELIPORT LIGHT LHE
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
