(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. 7-4)
●
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.

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. 7-6)

If there is a gap between the panel and the ceiling,
leave the ceiling panel attached and make fine

eliminate the gap with the ceiling. (Fig. 7-7)
