4. PREPARATIONS BEFORE INSTALLA-
TION
(1) Relative positions of indoor unit and suspension bolt.
(Refer to Fig. 2)
(2) Install a canvass duct to the air discharge outlet and air inlet
so that vibration from the machine body isn’t transmitted to
the duct or ceiling.
You should also apply sound absorbing material to the
inside of the duct, and vibration insulation rubber to the sus-
pension bolts.
(3) Install suspension bolts.
(Use bolts of 10 mm diameter.)
• Install the equipment where supporting structures are
strong enough to bear the equipment’s weight. Use
embedded inserts or anchor bolts with new buildings and
hole-in-anchors with old buildings.
5. INDOOR UNIT INSTALLATION
Installing optional accessories before installing the indoor
unit is easier.
As for the parts to be used for installation work, be sure to use
the provided accessories and specified parts designated by our
company.
(1) Fix the hanger bracket to the suspension bolt. Tighten both
upper and lower nuts firmly using washers.
(2) Adjust the height of the unit.
(3) Make sure the unit is
level.
• Level the unit with
a level when
installing. If the unit
is not level, it could
become the source
of water leaks.
• When leveling the
unit, check all four
corners with a level
or a vinyl tube con-
taining water. (See
the figure on the
right.)
(4) Tighten the nuts on the top.
(5) Insulate the two hanger brackets on the discharge side with
the sealing pad. (× 2) Insulate the edges so that the surface
and edges of the hanger brackets cannot be seen.

Setting the unit at an angle opposite to the drain piping
might cause leaks.
