3-6-2. Installing the Ceiling Panel
After completing the wiring process, install the supplied
wiring cover before installing the panel.
It is not possible to install the wiring cover after installing
the 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) 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. 3-20-1)
●
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 ceiling panel
while pressing the temporary fasteners toward the
outside. (Fig. 3-20-1)
(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. 3-20-2)
(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. 3-21)
●
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. (Fig. 3-21)
CAUTION
●
If the screws are not suffi ciently
tightened, trouble such as that shown
in the fi gure below may occur. Be sure
to tighten the screws securely.
