Low Voltage Inground Installation

Installation of inground fixtures requires special consideration. Proper grading, drainage material and tightly securing the lens and gasket are procedures that are key to a successful inground Installation. The following are basic steps in installing inground fixtures in either concrete (using Hadco concrete pour accessory) or soil. For greater detailed instructions, refer to the Installation: sheet enclosed with each Hadco fixture.

Low Voltage Inground Concrete Installation: (IL116 Shown)

NOTE: To ensure proper drainage, prepare gravel foundation. Make certain that the concrete level, when poured, will be flush with the top of the concrete pour accessory. To help decrease condensation, energize fixture for 20 minutes prior to installing and tightening main lens and retainer ring.

1. Remove trim ring and lens and install specified lamp. Replace trim ring and lens.
2. Position the fixture housing into the concrete pour accessory, making sure that the underside of the housing flange rests on top of the set screws. Tighten set screws on side of accessory to lock the housing into place (do not over-tighten). Secure assembly to the final location with re-bar or other anchoring device.
3. Excavate soil where the fixture is to be installed.
4. Place assembly into excavated opening. Be sure there is a minimum of 3" of drainage material (sand or gravel only) covering the bottom of the hole.
5. Fill area with a minimum of 3" of drainage material. Be sure not to fill area flush with top of frame and assembly. This is to be filled with concrete.
6. Connect low voltage fixture wire to low voltage cable running to remote transformer, using silicone wire nuts or quick connector (supplied).
7. Pour concrete. Remember that fixture position cannot be altered after the concrete sets.
8. Turn power on at transformer.

Low Voltage Inground Ground Installation: (IUL516 Shown)

NOTE: Do not place fixture in a below grade location as the fixture will collect dirt and debris and possibly become submerged in extremely wet conditions. Do not place plantings too close to the fixture as the foliage may grow over the light, blocking the light. Do not allow mulch to touch inground fixture in any way as this may cause the fixture to overheat and fail.

1. Excavate soil for fixture placement and conduit runs, making sure the fixture will be elevated and the grade sloped down from the fixture. Be certain to allow a minimum of 3" of drainage material (sand or gravel only) under and around the housing.
2. Remove trim ring and lens and install specified lamp. Replace trim ring.
3. After drainage material is installed in the bottom, place fixture housing into hole, back-filling a minimum of 3" of drainage material (sand or gravel only) around the side of the housing. Be certain that the underside of housing flange rests on top of grade level.
4. Connect low voltage fixture wire to low voltage cable running to remote transformer, using silicone wire nuts or quick connector (supplied).
5. Turn power on at transformer.
