AV-426-ICAO
Radio Controlled Solar Aviation Light
Maintenance and Servicing
Designed to be almost maintenance-free, the AV-426-ICAO requires minimal attention, though the
following maintenance and servicing information is provided to help ensure the life of your Avlite Systems
product.
1. Cleaning Solar Panels- occasional cleaning of the solar panels may be required. Using a cloth and
warm soapy water, wipe off any foreign matter before rinsing the panels with fresh water.
2. Battery Check- inspection of batteries should be performed every three years (minimum) to ensure
that the charger, battery and ancillary electronics are functioning correctly. Using a voltage meter,
check that the battery voltage is at least 12 volts under 100mA load, and ensure all terminals are clear
of foreign matter.
3. O-Ring Check- inspect the condition of the o-ring for damage, wear or if it is brittle, and replace if
necessary. The o-ring should be a rubber texture to ensure a complete and even seal.

Installing the Light Head Assembly on the Solar Unit
After servicing, it will be necessary to reinstall the light head on the solar unit.
1. Connect the 4 bullet connectors
2. Ensure the o-ring seal on the top of the solar chassis is in place, clean and lightly greased
3. Feed the wires into the corner of the solar unit
4. Locate the light head onto the solar unit in the correct orientation to the runway. The light head is fitted
with reflective tape indicators to show light output. This colour indication should be aligned with the
colour indication on the solar unit to ensure correct alignment.
5. Fit the 4 x M6 x 20 SHCS
6. Tighten the SHCS evenly and firmly.
It is recommended that the bolts for holding the light heads to the Solar Base units have a torque
setting applied of 3Nm for a satisfactory seal.
Applying a higher Torque setting is not recommended and may void warranty. If in doubt, please
contact your local Avlite representative.
7. Remove all tools, nuts and bolts from the runway
