[CEILING HEIGHT]
The indoor unit may be installed on ceilings up to 3.5 m in
height. However, it becomes necessary to make field settings
by remote controller when installing the unit at a height over
2.7m.
Refer to the section entitled “FIELD SETTING” and the decora-
tion panel installation manual.
Install this unit where the height of bottom panel is more than
2.5m so that user cannot easily touch.

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.
5-1 Fit the top nuts and washers over the
suspension bolts (×4).
• Use the washer fixing plate (5) to keep the washer from
falling out of place. Hang the unit from the hangers on
side A, and then fit the bottom washers and nuts over
the suspension bolts on that side.
(Refer to Fig. 17)
5-2 Install the indoor unit. (Refer to Fig. 18)
• Lock the unit to the hangers on side A.
• Hook the unit onto the other 2 hangers and lock with
bottom washers and nuts.
5-3 Check whether the unit is horizontally level
from sides C and D both. (Refer to Fig. 19)
CAUTION
• Do not hold the swing flap when mounting, as this
may break it.
• The indoor unit is equipped with a built-in drain pump and
float switch. At each of the unit’s 4 corners, verify that it is
level by using a water level or a waterfilled vinyl tube.
(If the unit is tilted against condensate flow, the float
switch may malfunction and cause water to drip.)
5-4 Remove the washer fixing plate (5) used for
preventing the washer from falling and tighten
the upper nut.
