1) Connect the connection wire securely to the terminal block. If the wire is not affixed completely, contact will be
poor, and it is dangerous as the terminal block may heat up and catch fire.
2) Take care not to confuse the terminal numbers for indoor and outdoor connections.
3) Affix the connection wire using the wiring clamp.
c) Attach the control lid.
4) Hanging the unit
Please arrange four sets of a hanging bolt (M10 or M8), a nut matching the bolt, a flat washer and a spring washer on the
installation site.
A . When hanging from the ceiling
a) When installing on a 2´ x 2´ grid ceiling, put in the unit on an angle, or hang the unit with
the T bar temporarily removed. When installing on a conventional ceiling, cut an insta-
llation opening (660mm x 660mm) in the ceiling, and hang the unit. When installing
on a conventional ceiling, cut an opening (Min 450 x 450) for inspection purposes.
b) Determine the positions of hanging bolts (530 x 530).
c) Use four hanging bolts, each fastened in such a manner that it can withstand pull force of 50kgf.
d) Make hanging bolts to the length that leaves approximately 45 mm of them above the ceiling. In hoisting the unit
main body in, temporarily fasten the four lower nuts of the hanging bolts approx. 93 mm from the ceiling and the
four upper nuts at positions sufficiently far from the lower nuts so that they may not hamper installation work when
the unit is hoisted in or the height is adjusted.
e) After hoisting in the unit , attach level gauges supplied as access-
ories and determine the unit position (height).To adjust height, use
the four lower nuts with the four upper nuts left loose. Please make
sure that the unit's four hanging fixtures touch the four lower nuts
and washers evenly without any play.
Use level gauges
as reference.

f) Please make sure that the unit main body is installed levelly. Level must be checked with
a level or a clear hose filled with water. (A tolerable height difference at an end of the
unit is within 3 mm)
g) After you have adjusted the height and level of the unit, fasten the four upper nuts to fix the unit.
Notes • Do not adjust the height with the upper nuts. It may cause deformation due to excessive force working on the
unit main body, which can result in such problems that you cannot attach the panel or noises are generated
from the interfering fan.
