Opening a ceiling and 
installation of hanging bolts

• Consider the piping/wiring after the unit is hung 

when determining the location of the indoor unit 
installation and orientation.

• After the location of the indoor unit installation 

has been determined, open the ceiling and 
install hanging bolts.

• The dimensions of the ceiling opening and 

hanging bolt pitches are given in the outline 
drawing and the attached installation pattern.

• When a ceiling already exists, lay the drain pipe, 

refrigerant pipe, indoor unit/outdoor unit 
connection wires, and remote controller wires to 
their connection locations before hanging the 
indoor unit.

Procure hanging bolts and nuts for installing the 
indoor unit (these are not supplied).

How to use the installation pattern

The installation pattern is provided inside the 
packaging cap.

<For existing ceiling>

opening and hanging bolts.

install the indoor unit.

• Hook the four holes in the installation pattern to 

the panel fixing screws of the indoor unit.

• When hanging a ceiling, open the ceiling along 

the outside dimensions of the installation pattern.

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.
(1) Cut and remove the ceiling foundation.

and add ceiling foundation for fixing the end of
