1.Locate the center point of the mounting location and insert the compass tool. Draw a circle.

2.Cut the circle out of the ceiling.

3.Use the mounting ring as a template and mark the screw hole pattern onto the mounting surface. Prepare the holes.

4.Install the mounting plates. Use the eight 10-32 x 3-inch screws (supplied) and install the mounting ring ￿and two back mounting plates ￿.

a. Line up the mounting ring with the eight fastener holes.

b.

Feed one back mounting plate ￿through the hole in the ceiling

and line up with four fastener holes.

c.Install fasteners through the mounting ring ￿, ceiling, and out the back mounting plate ￿.

d.Install second back mounting plate ￿.

5.Attach the conduit fitting, lock nut, and safety chain bracket. Install a safety chain/cable (not supplied) that will support up to 16 pounds (7.3 kg).

6.Open the hinged door to the back box. Push the tab lock towards the wall of the unit and lift the door open.

Pull wiring into the back box through the conduit fitting. Refer to Table A, Table B, and Table C for wiring distances.
