SIGNIFY HADCO I4 Installation Instructions page 2

INSTALLATION:
Housing/Conduit Excavation
Excavate soil for fixture placement and conduit runs. Contour the hole to the shape of the fixture
housing, allowing 3" minimum around and under the housing for placement of sand or other granular material.
If the installation is in concrete, the fixture must be placed on a 4" min. bed of gravel with soil below.
Use the CP4 accessory kit for I4 concrete installation.
Loosen the 8 screws on the lens retainer. Remove the retainer and lens/gasket assembly. Remove the
two screws and tabs holding the lamping assembly in place (if applicable). Remove the lamping assembly
from the fixture, unplugging the quick disconnect and set aside. For HID, loosen the two screws holding the ballast
plate, rotate and remove the ballast assembly. For Incandescent, remove wire compartment cover.
Connect conduit fittings to the housing utilizing a thread sealant. Tighten conduit fittings to 36 ft-lbs
maximum using a torque wrench. Improper torque procedure may cause damage to the fixture and void the
warranty.
Wires to fixture (rough wiring) are recommended not to be longer than 4" protruding out of wire compartment
to ensure potting compound covers wires.
Wire Compartment Sealing
WARNING:
- To ensure proper sealing, wire sealing compound is not re-enterable.
- Failure to follow potting procedure may allow water to leak into fixture, and void the warranty.
1.) Use supplied silicone filled blue wire nuts to connect fixture wires to supply wires, including ground.
2.) Apply supplied Duct Seal to conduit entry and ensure completely sealed. Failure to do so will allow potting
compound to run down conduit.
3.) Since potting only covers ¾ of the wiring compartment, wires need to be pressed into the compartment prior to
potting so only 3 fixture wires protrude out of the potted compartment. Mix 3M 2130, Scotchcast, 2 part
non re-enterable compound per instructions on package, and completely cover all wires and connections.
Any remaining exposed wires must be pressed into potting compound.
4.) Additional potting material can be ordered (catalog #: MA5).
Fixture Re-Assembly
Replace ballast plate assembly (HID) or wire compartment cover (Incandescent) and tighten screws.
Re-connect the quick disconnect from the lamping assembly to the ballast plate. Replace lamping assembly
as well as tabs and screws, if applicable. For T6 optics, position the bottom band of the lamping assembly
around the four pins indicated in the "T6 Optics - Seating Illustration" below [left] and simply press-fit into place.
Install the specified lamp. Do not exceed the maximum wattage marked on the fixture. Aim lamping assembly
to desired position and tighten wing nuts or thumbnut on side(s) to lock in place. For T6 optics, an aiming label is
attached at the top of the fixture to help aid in aiming when several fixtures are used or to retain the aiming
direction after re-lamping.

Note: To help decrease condensation, energize fixture for 20 minutes prior to installing and tightening main lens
and retainer ring. All gasket seating surfaces must be clean and free of debris before attempting to replace the
retainer. If debris in the screw holes prevents proper seating of the gasket, holes must be blown clear or cleared with
a #10-24 tap. Insert screws through the retainer and tighten, using an alternating torque sequence of 20-30
inch-lbs. See "Torque Sequence Illustration" above [right].
Backfilling & Landscaping
When backfilling, housing flange should be just above ground level as shown. Fixture housing should
be surrounded by a 3" minimum layer of sand or gravel to ensure proper drainage. It is recommended that
fixtures not be placed in low locations where water could accumulate and stand for long periods of time.
When installing fixture, hilling up earth around fixture will promote good water run-off and prevent debris
accumulation.
