Recommended tightening torque:
0.78 N·m {0.58 lbf·ft}
Step 6
Secure the mounting chassis to the ceiling
board with the ceiling board fixing screws (4
positions, screws with label
q
).
Engage the top of the mounting chassis
q
with the anchor bolt (for securing the
mounting chassis).
Secure the mounting chassis by turning the
w
ceiling board fixing screws clockwise when
viewing it from beneath. Turning the ceiling
board fixing screws clockwise provides ceil-
ing board tightening between the bottom of
the mounting chassis and ceiling board fix-
ing bracket resulting in mounting chassis
securing.
Recommended tightening torque:
0.78 N·m {0.58 lbf·ft}
Important:
When securing the mounting chassis on
•
the ceiling, make sure that the 4 ceiling
board fixing brackets are open as shown in
the figure
