(4) Wiring the Ceiling Panel
1) Open the cover of the electrical component box for control
PCB.
2) Connect the 22P connector (white) from the ceiling panel
to the connector on the control PCB in the unit electrical
component box. In this case, expose the cutout section
of the tube for the wiring protection to the outside from
the electrical component box and fix it with the clamper
attached to the electrical component box.
If the connectors are not connected, the Auto Flap will
not operate. Be sure to connect them securely. (If not
connected completely, "09" will be displayed on the
remote controller.)
Check that the wiring connector is not caught between
the electrical component box and the cover.

(5) How to Attach the Corner & 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 figure below.
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 "Removing
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's requests.
When attaching the air-intake grille, be careful that the flap
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 figure below.
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's requests, as shown in
the figure below. However, the wireless signal receiver can
only be installed at the refrigerant-tubing corner of the ceiling
unit.
