Installation & Safety Notes
Before installing the YFFY-THD-155 Integrated Solar Marine Lantern, carefully read all installation instructions and verify that the selected mounting location meets the operational requirements of the application.
Install the lantern on a stable, level mounting surface using the recommended hardware to ensure maximum mechanical stability and optimum optical performance. Position the solar panels where they receive unobstructed sunlight throughout the day, avoiding shadows from nearby structures, vegetation, or equipment that could reduce charging efficiency.
Ensure the lantern is securely fastened and all mounting hardware is properly tightened before commissioning. If optional GPS synchronization or remote monitoring functions are installed, verify that all electrical connections and communication interfaces are correctly configured and protected against moisture ingress.
To maintain reliable long-term performance, periodically inspect the lantern for physical damage, clean the solar panels and lens with a soft cloth and fresh water to remove salt, dust, or other contaminants, and confirm that the mounting hardware remains secure. Avoid using abrasive materials or chemical solvents that may damage the optical lens or protective coatings.
If the lantern will be removed from service for an extended period, store it in a clean, dry, and well-ventilated environment away from excessive heat, corrosive chemicals, or prolonged moisture exposure.
