1. Preparation Before Installing the Ceiling Panel
Position check of indoor unit
1. Confirm the position of the indoor unit according to the
installation Manual.
2. Check whether size of the ceiling opening hole is in the
following range or not.
860 mm × 860 mm to 910 mm × 910 mm
3. 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.)
Be sure to adjust the position between the indoor
unit and the hanging-up height (12 mm to 17 mm).
Failure to do so cause the malfunction or other
damages.
