Attaching the corner cover and air-intake grille
A. Attaching the corner cover
(1) Check that the safety cord from the corner cover is
fastened to the ceiling panel pin, as shown in the
fi gure. (Fig. 3-49)
(2) Use the supplied screws to attach the corner cover
to the ceiling panel.
B. Attaching the air-intake grille
●
To install the air-intake grille, follow the steps for
the grille in the reverse order. By rotating the air-intake
grille, it is possible to attach the grille onto the ceiling panel
from any of 4 directions. Coordinate the directions of the
air-intake grilles when installing multiple units, and change
the directions according to customer requests. (Fig. 3-50)
●
When attaching the air-intake grille, be careful that the
fl ap lead wire does not become caught.
●
Be sure to attach the safety cord that prevents the
air-intake grille from dropping off to the ceiling panel
unit as shown in the fi gure at right.
●
With this ceiling panel, the directions of the air-intake grille
lattices when installing multiple units, and the position of the
label showing the company name on the corner panel, can
be changed according to customer requests, as shown in
the fi gure below. However, the optional wireless receiver kit
can only be installed at the refrigerant-tubing corner of the
ceiling unit. (Fig. 3-51)

3-13-5. Checking After Installation
●
Check that there are no gaps between the unit and the ceiling panel, or between the ceiling panel and the ceiling surface.
Gaps may cause water leakage and condensation.
●
Check that the wiring is securely connected.
If it is not securely connected, the auto fl ap will not operate. ("P09" is displayed on the remote controller.) In addition, water
leakage and condensation may occur.
3-13-6. When Removing the Ceiling Panel for Servicing
When removing the ceiling panel for servicing, remove the air-intake grille and air fi lter, disconnect the wiring connector inside the
electrical component box, and then remove the 4 mounting screws.
3-13-7. Adjusting the Auto Flap
The air-direction louver on the ceiling panel outlet can be adjusted as follows.
●
Adjust the louver to the desired angle using the remote controller. The louver also has an automatic air-sweeping mechanism.
NOTE
● Never attempt to move the louver by hand.
●
Proper air fl ow depends on the location of the air conditioner, the layout of the room and furniture, etc. If cooling or heating seems
inadequate, try changing the direction of the air fl ow.
