4. INSTALLING THE INDOOR UNIT
(1) Lift unit so that suspension bolts pass through the
suspension fittings at the sides (four places), and
slide the unit back. (See Figs. 13 and 14.)
(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.
In order to check the drainage, be sure to
use a level during installation of the
indoor unit. If the installation site of the
indoor unit is not level, water leakage
may occur.
[If using anchor bolts]
(1) Drill holes for anchor bolts at the locations at which
you will set the suspension bolts. Note that anchor
bolts are M10 bolts (to be obtained locally).
(2) Install the anchor bolts, then temporarily attach spe-
cial nut “B” (included) and a locally-procured M10
nut to each of the bolts. (See Fig. 12.)
[For Half-Concealed Installation]
When installing the indoor unit in a semi-concealed
orientation, 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.

locations.
