(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.

 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. 7-5)
Fig. 7-5
  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. 7-6)
Fig. 7-6
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. 7-7)
