3-13-2. Installing the Ceiling Panel
The power must be turned ON in order to change the fl ap
angle. (Do not attempt to move the fl ap by hand. Doing so
may damage the fl ap.)
(1) Hang the temporary latches on the inside of the
ceiling panel to the receptacle on the unit to
temporarily attach the ceiling panel in place.
(Fig. 3-44)
●
The ceiling panel must be installed in the correct direction
relative to the unit. Align the REF. PIPE and DRAIN marks on
the ceiling panel corner with the correct positions on the unit.
(2) Align the panel installation holes and the unit screw
holes. (Fig. 3-45)
(3) Tighten the supplied washer head screws at the 4
panel installation locations so that the panel is
attached tightly to the unit.
(4) Check that the panel is attached tightly to the ceiling.
(Fig. 3-46)
●
At this time, make sure that there are no gaps between the
unit and the ceiling panel, or between the ceiling panel and
the ceiling surface.
●
If there is a gap between the panel and the ceiling, leave the
ceiling panel attached and make fi ne adjustments to the
installation height of the unit to eliminate the gap with the
ceiling.

If the screws are not suffi ciently
tightened, trouble such as that shown
