Inground Fixture Installation Guidelines
Please refer to the below general installation guidelines for inground fixtures.
- Inground fixtures are typically IP67 rated for temporary water submergence and not IP68 rated for permanent submergence. They are not "pond lights". Thus proper drainage and avoidance of excessive water in fixture recess should be prevented. If inadequate installation and water build up is found, warranty on fixtures may be rendered void.
- Adequate gravel should be allowed for below fixture to ensure excess water drains out well.
- If gravel is not possible (concrete slab etc) a drainage pipe should be installed below fixture to drain out any water buildup in recess.
- Ensure cutout/sleeve is matching outer diameter of fixture. If the cutout/sleeve is too big excessive water ingress will seep on the sides of the outer flange and fixture would be loose.
- Ensure flange of fixture sits flush with final finish of ground/floor finish. Excessive gaps/uneven surfaces would allow excessive water to seep trough.
- In difficult installation situations where the above can not be achieved, the fixture recess can be resin/gel filled to ensure no water enters the recess. Ensure a removable gel is used in this scenario. Example of gel can be found from this link.
- Water ingress is possible through cables, as the fixture heats up and cools down it can actually "suck" water trough the cable like a straw. This happens over time and can cause fixtures to fail months/years after install. Thus wiring connections should be fully IP68 rated to ensure no water ingress is possible through the cable itself.
- Ideally the connection should be adjacent to fixture in a resin/sealed junction box.
