HOW TO INSTALL THE CEILING PANEL
■

(AS Type)
10-1.
Installing the Ceiling Panel
(1)
Screw the M5
✕
40 screws supplied (in the unit packing) into 4 points on the flange surface of the unit
bolted to the ceiling. Insert the screws so that the distance between the bottom of the screw head and the
bottom surface of the flange is at least 19.05 mm. (Fig. 10-1)
(2)
Next, lift the ceiling panel in this position so that the 4 protruding screws pass through the key hole-shaped
openings in the panel, then shift the panel sideways until it is caught by the screws.
(3)
Keeping the ceiling panel in this position, check to see if the joining edge of the ceiling panels are in line
with those of the ceiling material.
If they are not in line, remove the ceiling panel and finely adjust the suspension position of the unit.
(4)
Once the joining edges are properly aligned with each other, install the supplied stoppers into the
key hole-shaped openings, then insert the 4 screws until the ceiling panel touches the flange surface of
the unit.

securely in the hole, A and B, then tighten the screw. (Fig. 10-1)
