Remove the knockout plug (K) closest to the electrical service (L) on the fixture housing (F). 4. Mount fixture housing (F) over anchor bolts (A) pulling the electrical conductors from service into the fixture housing (F). Tighten the bolts ensuring that the ceiling gasket (M) is properly seated against the ceiling. 5. Place the end-to-end gasket (E) on the end of the fixture housing (F), aligning the gasket (E) to the through holes. Lift and align the adjacent fixture housing (F) to be installed against the end-to-end gasket (E) and over the anchor bolts (A). Insert three 1/4-20 screws (G) through the ends of the adjacent fixture housings, threading the three 1/4-20 nuts (H) on to the screws (G). Thread anchor bolt nuts onto anchor bolts (A). Tighten the three 1/4-20 end nuts (H). Tighten the anchor bolt nuts, ensuring the ceiling gasket (M) is properly seated against the ceiling surface. Repeat step #5 until all fixture housings (F) are mounted to the ceiling. 6. Connect the electrical service conductors to the housing wiring harness (N) and to the through branch circuit conductors (O) - per the “Close Up Detail - Through Branch Wiring” (see page 2). 7. Connect the housing wiring harness (N) to the reflector/ballast assembly wiring harness (P). 8. Re-install the reflector/ballast assembly (C) to the fixture housing (F) via the 1/4 turn fasteners (D). 9. Install the lamps (Q) into the fixture.
