Checking the unit position
(1) Check that the ceiling hole is within this range:
600 × 600 mm
(2) Confirm that the positions of the indoor unit and the ceiling
are as shown in the diagram. If the positions of the ceiling
surface and unit do not match, air leakage, water leakage,
flap operation failure, or other problems may occur.
CAUTION
● Never place the panel face-down. Either hang it
vertically or place it on top of a projecting object.
Placing it face-down will damage the surface. (Fig. 7-12)
A must be within the range of 13 – 18 mm. (Fig. 7-12)
If not within this range, malfunction or other trouble may
occur.

7-5. Installing the Ceiling Panel
The power must be turned ON in order to change the flap
angle. (Do not attempt to move the flap by hand. Doing so may
damage the flap.)
(1) Hang the temporary latches on the inside of the ceiling
panel to the receptacle on the unit to temporarily attach the
ceiling panel in place. (Fig. 7-18)
● The ceiling panel must be installed in the correct direction
relative to the unit. Align the REF. PIPE and DRAIN marks
on the ceiling panel corner with the correct positions on the
unit.
● To remove the ceiling panel, support the ceiling panel while
pressing the temporary latches toward the outside.

ceiling. (Fig. 7-21)
Can be installed rotated 90°

(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. 7-24)
