Even if it is during guaranteed period, the manufacturer is not responsible for any hazard or damage caused  z
by using a ceiling mount bracket which is not purchased from an authorized distributors, or environmental 
conditions.
Remove an unused ceiling mount bracket promptly. z
Ensure to use a torque driver and do not use an electrical screwdriver o\
r an impact screwdriver. z
For details, see the work instruction manual packed together with the ce\
iling mount bracket. z
The model Nos. of the accessories and the parts sold separately are subject to change without notice. z
Make sure the screws on the ceiling mount kit cannot touch the metal par\
ts materials (metallic lath, wire or  z
board) in the ceiling board. Otherwise it may result in fire hazard.
