6 Maintenance
6.1 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 front glasses are not included in the warranty.
6.2 Maintenance in the Field
It is recommended to limit field maintenance to cleaning the front glasses. The light fixtures should be
replaced at regular intervals and overhauled in the maintenance workshop.
•
Every 6 months:
•
Check the alignment of light fixtures and adjust if necessary (See Adjustment on page 19.)
•
Regularly:
•
Clean the front glass if necessary.

Perform a visual check that both light fixtures display a similar light output.
