* 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.
