(2) Fasten the indoor unit into place by tightening-up
the special "B" bolts and the M10 nuts. Make sure
that unit is secure and will not shift back and forth.
[For Half-Concealed Installation]
When installing the indoor unit in a semi-concealed
shape, make sure to reinforce the insulation of the unit
on all sides. Drops of water may fall from the unit if it
is not thoroughly insulated.

In order to check the drainage, be sure to
check a level during installation of the
indoor unit. If the installation site of the
indoor unit is not level, water leakage
may occur.
