SLTH – SEMI-FLUSH THRESHOLD LIGHT
INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
4
/
Splice the light base leads to the power cables using solderless squeeze
connectors, as shown in the figure, crimped with the proper tool.
Connect also the grounding wire to the main grounding network by using
a suitable clamping lug.
ATTENTION: Insulate each splice carefully using either heat
shrinkable insulating tubing properly applied or at least three
layers of plastic electrical insulating tape applied with half overlap.
5
Mount the positioning jig (P/N 332.4301) on the base as shown in fig.11.
An optical device for proper fixture orientation is available (P/N
332.4351 fig.12).
6
/
Properly arrange the leads in the wireways using small pieces of
insulating tape if necessary.
7
Completely cover the bottom of the base with sealer material, apply a
thin coat of sealer to the bottom of the drilled hole to assure a bond
between the bottom of the light base and the drilled hole. It may be
necessary to place temporary plugs so as to block the wireways
entrances into the drilled hole (METHOD “A”) or the cable ducts
entrance (METHOD “B”). The plugs will retain the sealer while it begins
to dry up.
ATTENTION: avoid starting the installation when the ambient
temperature is below 10°C (86°F), unless the sealer used is
designed to dry up at a lower temperature.
8
Push the base into the recess until its upper side is at the level of the
pavement surface; take care no sealer flowing inside the base. Align the
notch of the base with the markings on the pavement surface.
9
/
Observing the circular level fixed on the jig, level the jig by operating the
three leveling lobe knobs (fig.11). If necessary, a weight may be placed
on the jig to hold the light base in position.
The remainder of the space between the sides of the shallow base and
the drilled hole should be filled with sealer up to approx 25 mm from the
pavement, according to the local needs.
Fill the remaining 25 mm with a suitable joint sealing filler.
