If a gap remains between the ceiling surface and the
ceiling panel even after the screws are tightened,
adjust the height of the unit again.
Adjust so that there
are no gaps.
If there is no affect to the horizontal
of the unit and drain tube, adjustment
to the installation height of the unit
can be made through the hole of the
ceiling panel corner.
(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.

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.
