Setup and Installation
The LyLmLe pool light is designed for easy installation without the need for complex tools or emptying your pool. It utilizes a magnetic design for secure attachment.
Installation Steps:
- Prepare the Surface: Ensure the desired installation area on the pool wall is clean and free of debris.
- Magnetic Attachment (Steel/Metal Pools): For pools with steel or metal walls, simply place the light on the inside of the pool wall. The strong built-in magnets will firmly adsorb to the surface.
- Magnetic Attachment (Non-Steel Pools): For non-steel pool walls (e.g., fiberglass, vinyl liner), use the supplied metal base. Place the metal base on the exterior of the pool wall at the desired location. Then, place the light on the inside of the pool wall, aligning it with the external metal base. The magnets will secure the light in place.
- Connect Power: Plug the power cord into a standard 110V AC outlet. Ensure the outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for added safety.
