d) Installation with enclosed bracket
Use this method when installing onto a gypsum board (7 or 18 mm), etc.
1
Catch the two protrusion of the enclosed bracket onto the fitting as shown above, and temporarily fix with the screws.
(The bracket has an up/down and front/back orientation. Confirm the top/bottom protrusion positions and the positional
relation of the ø 10 holes on the bracket and the installation hole on the lower case with the above drawing.)
2
Insert the end of the installation fitting into the back of the ceiling from the opening, and tighten the screws to fix the
bracket onto the ceiling.
3
Pass the wiring from the rear side through the hole on the lower case.
4
Fit the lower case onto the bracket, and fix the lower case to the bracket using the two installation holes shown above.
(The other four holes are not used.)

e)
Direct installation onto the ceiling with wood screws
Use this installation method when the ceiling is wooden, and there is no strength-wise problem in installing directly with
wood screws.
Fit the lower case into the ceiling opening. Make sure that the convex section on the back of the lower case and the
clearance with the ceiling opening are as equal as possible on both sides.
Using the two installation holes shown above, fix the lower case onto the ceiling with the enclosed wood screws.
(The other four holes are not used.)
Fit the upper case onto the lower case, and tighten the screw.
