How to Attach the Corner and Air Intake Grille
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. 2-23).
Pin
Place the corner cover so that the 3 tabs fit into the
holes in the ceiling panel. Then fasten it in place with the
supplied screws.
(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 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. 2-24)
