9-2. Installing the Ceiling Panel
The power must be turned ON in order to change the
flap angle. (Do not attempt to move the flap by hand.
Doing so may damage the flap.)
(1) Insert the temporary fasteners (stainless steel)
on the inside of the ceiling panel into the square
holes on the unit to temporarily fasten the ceiling
panel in place. (Fig. 9-7)
●
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.
●
To remove the ceiling panel, support the ceil-
ing panel while pressing the temporary fasteners
toward the outside. (Fig. 9-7)
(2) Align the panel installation holes and the unit
screw holes.
(3) Tighten the supplied washer head screws at the
4 panel installation locations so that the panel is
attached tightly to the unit. (Fig. 9-8)
(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 ceiling panel, or between
the ceiling panel and the ceiling surface. (Fig. 9-9)
●
If there is a gap between the panel and the ceil-
ing, leave the ceiling panel attached and make fine
adjustments to the installation height of the unit to
eliminate the gap with the ceiling. (Fig. 9-10)
CAUTION
●
If the screws are not sufficiently
tightened, trouble such as that
shown in the figure below may
occur. Be sure to tighten the
screws securely.

If a gap remains between the

panel even after the screws
are tightened, adjust the
height of the unit again.
Adjust so that there are no gaps.

The height of the unit can be adjusted from
the ceiling panel corner hole, with the ceil-
ing panel attached, to an extent that does
not affect the unit levelness, the drain hose,
or other elements.
