3) Tighten the provided washer head screws at the 4 panel installation locations so that the

4) Check that the panel is attached tightly to the ceiling.
● At this time, make sure that there are no gaps
between the unit and the panel for cassette, or
between the panel for cassette and the ceiling
surface.
● If there is a gap between the panel and the
ceiling, leave the panel for cassette attached
and make fine adjustments to the installation
height of the unit to eliminate the gap with the
ceiling.
CAUTION
● If the screws are not sufficiently tightened, trouble such as that shown in the figure
may occur.
Be sure to tighten the screws securely.
● If a gap remains between the ceiling surface and the panel for cassette even after the
screws are tightened, adjust the height of the unit again.
Adjust so that there
are no gaps.
