To install the dmf H3BH H-Series New Construction with Bar Hanger, follow these steps:
1. Before starting installation, ensure that the power to the luminaire is turned off to prevent electric shock.
2. Locate the desired fixture position and locate the AC pigtail.
3. Install the bar hanger ends into the joists by nailing in four nails (factory installed) or screws at the end of the bar hangers. Note that the bar hangers are compatible with 16" - 24" spacing, but can be cut on scored sections to go down to 12" spacing.
4. Adjust the horizontal position of the housing by sliding it along the bar hangers. Locate the center according to the fixture location.
5. Lock the horizontal positioning by fastening both bar hanger screws (factory installed).
6. Route the electrical wires through the wiring compartment using Romex tabs or knockouts.
7. Connect the hardwire adapter (included) to the housing electrical leads.
8. Mark the center fixture position on the drywall.
9. Cut an opening in the drywall and install the drywall (the housing is compatible with ceiling thicknesses of 1/2" to 5/8"). For the H3BH model, cut out a 3 1/2" [89mm] opening, and for the H4BH model, cut out a 4 1/2" [114mm] opening.
To install the module:
1. Align the trim onto the module and snap it on.
2. Attach the module ground wire to the building ground following national and local electrical codes.
3. Connect the module connector.
