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.

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

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.
