Confirm the position of the indoor unit
according to the Installation Manual.

Using the installation gauge which is attached
to the indoor unit package, determine position
of the indoor unit against the ceiling surface. If
the position of the indoor unit is not correct, air
leak, water leak (dewing), or malfunction of the
louver is caused.
• Do not put the ceiling panel downward, lean it, or
leave it on a projection to avoid a damage on the
surface of the ceiling panel.
• Handle with care so as not to deform the tentative
hanging hooks attached to the rear side of the
ceiling panel.
• Do not apply excessive force on the louver or the
styrofoam on the air outlet while hanging it
tentatively to the indoor unit. (It may causes a
trouble on the louver.)
