(3) 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) 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. 1-134)
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.
When removing the ceiling panel, push the temporary latches
outward while holding the ceiling panel.

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. 1-136)

If there is a gap between the panel and the ceiling, leave the ceiling
panel attached and make fine adjustments to the installation height
of the unit to eliminate the gap with the ceiling. (Fig. 1-137)
