7-1. Preparation for Ceiling Panel Installation
(1) Checking the unit position
1) Check that the ceiling hole is within this range:
860 mm × 860 mm to 910 mm × 910 mm
2) Confirm that the position of the indoor unit and the
ceiling 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.
●
Do not touch the flap or apply force to it.
(This may cause flap malfunction.)
