Correct Installation of Underwater Pool Luminaires

Care must be taken to ensure the design and installation of any underwater lighting product is completed carefully and with the correct methods.

Make local connections in a dry intermediate location or junction box to avoid the need for abnormally long cables to be factory fitted to luminaire. Intermediate connection/junction box must be at least 300mm above the water line. Ensure your installer has a defined installation and wiring plan and contact the manufacturer in advance in case of any uncertainty.

The end of cables and wiring must not at any time get wet or come into contact with water whatsoever. If retrofitting, all water must be drained completely and the area must be 100% dry

Do not at not at any time operate any submersible-only luminaire outside of cool water. Only after submersion should power be energised.

To maximise lifespan, you should not operate underwater lighting continuously for more than 4-6 hours at any time
