WARNING
Install the air conditioner certainly to sufficiently withstand the weight.
If the strength is insufficient, the unit may fall down resulting in human injury.
Perform a specified installation work to guard against earthquake.
An incomplete installation can cause accidents by the units falling and dropping.
CAUTION
Strictly comply with the following rules to prevent damage of the indoor units and human injury.
Do not put a heavy article on the indoor unit or let a person get on it. (Even units are packaged)
Carry in the indoor unit as it is packaged if possible. If carrying in the indoor unit unpacked by necessity, use
buffering cloth or other material to not damage the unit.
To move the indoor unit, hold the hooking brackets (4 positions) only.
Do not apply force to the other parts (such as refrigerant pipe, drain pan, foamed parts, or resin parts).
Carry the package by four or more persons, and do not bundle it with plastic band at positions other than
specified.
To install vibration isolation material to hanging bolts, confirm that it does not increase the unit vibration.

Installation of hanging bolt
Consider the piping / wiring after the unit is hung to
determine the location of the indoor unit installation
and orientation.
After the location of the indoor unit installation has
been determined, install hanging bolts.
For the dimensions of the hanging bolt pitches, refer
to the external view.
When a ceiling already exists, lay the drain pipe,
refrigerant pipe, control wires, and remote controller
wires to their connection locations before hanging
the indoor unit.
Procure hanging bolts washer and nuts for installing
the indoor unit (these are not supplied).

Installation of indoor unit
Treatment of ceiling
The ceiling differs according to structure of building.
For details, consult your constructor or interior finish
contractor.
In the process after the ceiling board has been
removed, it is important to reinforce ceiling foundation
(frame) and to keep horizontal level of installed ceiling
correctly in order to prevent vibration of ceiling board.
Attach the nuts and the W3/8" (M10) flat washers
to the hanging bolt.
Put washers at up and down of the hanging bracket
of the indoor unit to hang down the indoor unit.
Check that four sides are horizontal with a level
gauge. (Horizontal degree: Within 0.2" (5 mm))
