Mounting the installation plate

When the installation plate is directly mounted 
on the wall

1. Securely 

fi

 t the installation plate onto the wall by screwing it in the upper 

and lower parts to hook up the indoor unit.

anchor bolt holes as illustrated in the below 

fi

 gure.

3.  Install the installation plate horizontally in the wall.

When installing the installation plate with a mounting screw, do not use 
the anchor bolt holes. Otherwise, the unit may fall down and result in 
personal injury and property damage.  

1.  After determining the pipe hole position on the mounting plate (

), drill the 

pipe hole (dia. 65 mm) at a slight downward slant to the outdoor side. 

•  A place which provides the spaces around the indoor unit as shown in the 

diagram

•  A place where there are no obstacles near the air inlet and outlet
•  A place which allows easy installation of the piping to the outdoor unit
•  A place which allows the front panel to be opened
•  The indoor unit shall be installed as top of the indoor unit comes to at least 

2 m height. Also, it must be avoided to put anything on the top of the indoor 
unit.
