Note: Ensure that you trace the back of the outer plate: this is the side with the
smaller diameter. If you trace the diameter of the front of the plate, your mounting
hole will be too large.
3) Trace the outline of the back of the outer plate onto the ceiling
panel.
4) Use the traced outline as a guide to cut out the mounting hole.
To install the back and outer plates perform the following.
1) From the inside of the back plate, insert the three M5x20 pan-head
double-washer screws into the three holes.

plate.
2) Set the back plate onto the back of the ceiling panel and center it
over the mounting hole.
3) Slide the outer plate into the mounting hole and back plate.
4) Line up the mounting holes and slots in the outer plate with the
three M5x20 pan-head double-washer screws in the back plate.
5) Slide the outer plate onto the screws in the back plate.
6) Rotate the outer plate counterclockwise to secure it to the back
plate.
To install the housing perform the following.
1) Let the housing cover drop down and rest on the hinge.
2) Attach the housing to the inner plate using the M4x12 pan-head
double-washer screws.
3) Slide the back of the housing and attached inner plate into the
outer plate.
4) Rotate the housing counterclockwise to slide the mounting slots on
the inner plate onto the screws in the back plate.
