Maintenance and Product Care
Although the A-704-5 light is designed to be maintenance-free, significant performance gains can be
made with clean solar panels and lenses. Clean the solar panels monthly. Use water and a soft sponge or
cloth. A mild non-abrasive cleanser can be used for more stubborn residue. Rinse well.
The following other maintenance precautions should also be taken:
Clean solar panels and lenses more frequently during drier months, as they may become covered in
dust more quickly. A pressure washer is not recommended.
Visual inspection – check the exterior for cracks, missing or broken hardware or other potential
problems.
