* The length of the suspension bolts 
should be selected so that there is 
a gap of 30 mm or more below the 
lower surface of the ceiling (18 mm 
or more below the lower surface of 
the main unit), as shown in the 
figure at right. If the suspension 
bolt is too long, it will contact 
the ceiling panel and the unit 
cannot be installed.
