●
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.

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. (Fig. 9-13)
(2) Use the supplied screws to attach the corner cover to the
ceiling panel.
Place the corner cover so that the 3 tabs

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 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 to the ceiling panel
unit. This keeps the air intake grille from accidentally
dropping. (Fig. 9-14)
