3 General recommendations
3.1 General Recommendations
3.2 Electrical Connection
The light assemblies covered by this manual are designed for connection to 6.6 or 20-A series circuits via
one or two L-830 or L-831 series transformers. The current to the light should not exceed 6.6 A + 5%. The
series transformers are to be ordered separately.
3.3 Base Earthing
Whatever the chosen installation method, it is strongly recommended to earth the base, especially in
locations presenting a risk of lightning strikes. Failure to earth the base correctly will void the warranty for all
damages occurring as a result of voltage surges.
1. Loosen the lower-right bolts with a SW13 wrench.
2. Position the earth connector as shown.
3. Retighten the bolts to 9 Nm.
4. Connect the earth wire according to the shallow base installation instructions.

4 Maintenance Recommendations
4.1 Warranty Limitation
The light assemblies are delivered fully tested and sealed. In case of malfunctioning during the warranty
period, the defective light shall be shipped back to TKH Airport Solutions without opening it. Any attempt to
open the light during the warranty period will void the warranty. The prisms are not included in the warranty.
4.2 In the Field Maintenance
The light assemblies can be serviced in the field, but it is recommended to limit field maintenance to cleaning
the prisms. It is recommended to replace the inset lights at regular intervals and to have them overhauled in
the maintenance shop. The same applies to lights found unserviceable in the field.
4.3 Preventive Maintenance
The light assembly’s service life depends to a large extent on its waterproofness. All metal mating surfaces
and seals must be clean, smooth, dry, and free of all foreign particles if the light fixture is to operate for
extended periods without requiring maintenance. Greasing of O-ring seals may be required.
Maintenance frequency depends on the conditions under which the runway is used (i.e. climate, traffic, etc.).
The recommended practices for maintenance are described in the FAA advisory circular no. AC 150/5340-26
and in the ICAO Aerodrome Design Manual, Part 9 Airport Maintenance Practices.
