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

2.Cut out the circle.

3.Use the mounting ring as a template to 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) to install the mounting ring (A) and the two back mounting plates (B).

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

b.Feed one back mounting plate (B) through the hole in the ceiling (C). Line up the plate with the four fastener holes.

c.Install fasteners through the mounting ring (A), ceiling, and out the back mounting plate (B).

d.Install the second back mounting plate (B).

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

6.Open the hinged door to the back box. Push the tab lock toward the wall of the unit and lift the door open. Pull the wiring into the back box through the conduit fitting. Refer to Table A, Table B, and Table C for wiring distances.
