Installing the Model A704-5 Aviation Light
7.1 Installation
Installation typically takes very little time. For stability and safety, a minimum of three fasteners is
recommended, placed 120
°
apart. To protect the top surface of the mounting base from damage, use a
washer under the head of the fastener.
It is a good idea to test the light before heading out into the field; the light does not
need to be mounted before programming and testing can occur. Try the different
functions to ensure the light is working properly and to become familiar with the
behavior of the light.
7.2 Optional Airport Mounting Stake
The Model A704-5 Aviation light can also be installed using an optional airport mounting stake. Made of
galvanized steel, the airport mounting stake is suitable for permanent installation in earth and gravel. The
30" (76.2 cm) airport mounting stake is available in 2" (5.08 cm) and 1.5" (3.81 cm) frangible coupling
sizes.
Coupling size must be determined before ordering.
Stake (Angle Iron) Mounting Instructions:
Using an auger, drill a 3" (7.62 cm) to 4" (10.16 cm) diameter hole to a depth of 30" (76 cm). Install the
top of the stake even with, or not more than 1/2" (1.3 cm), above the finished grade and maintain within 1
degree of the vertical. Backfill around the stake with thoroughly compacted earth (or suitable backfill
material such as sand or concrete). For hard bedrock or sediment areas, 15” (38.1 cm) stakes can be
used. In areas where frost may cause heaving, anchor the stake with concrete and use a permeable
backfill material such as sand and then cover the top surface with an impervious material to reduce
moisture penetration.
7.3 Location
Observe the following precautions to ensure optimal performance:
Mount the light in direct sunlight. Any shadow or shading of the solar panels will prevent the light’s
ability to charge.
Avoid mounting the light directly in contact with tarmac or asphalt. Temperatures of these surfaces
during the summer can rise above the maximum recommended operating temperatures of the light. If
the light must be mounted on tarmac, asphalt or other similar dark surface, place a square of plywood
or other thermally insulating material between the base and the mounting surface.
Lights mounted close to each other may sense each other’s emitted light and turn off (if programmed
in Autonomous Mode). Recommended minimum separation is 6 feet (2 m) between lights to prevent
this from occurring.
