IMPORTANT
Proper transformer wattage is dependent on the configuration options of
your light unit(s) and is necessary for meeting ICAO specifications. See
section 12, tables 2 and 3 for minimum transformer requirements.
8.1 Specifying the Location
The correct orientation of the light units is extremely important. Refer to ICAO Annex14, Volume I, 4th
edition, July 2004 paragraph 5.3.16 when determining the location for light unit. Read and understand all
instructions to guarantee correct location of each unit.
8.2 Installation of a Light Unit
Verify that the mounting flange and gasket sealing surfaces on the light base are clean. Coat the
optional
gasket
on the inner cover with Dow Corning FS 1292 grease. Connect the plug(s) from the light unit to the
secondary(ies) of the previously installed isolation transformer(s). Lower the light unit straight down onto
the base. The light unit is subject to optical misalignment or mechanical damage if not seated properly.
Verify the light beam(s)/color(s) are properly oriented for the individual location and that wires are not
pinched. Select and install the proper length mounting bolt and lock washers per section 8.4. After
installation, the mounting bolts should be periodically checked for proper torque to ensure a secure
installation. See section 9.10.4.
