5. INDOOR UNIT INSTALLATION



As for the parts to be used for installation work, be sure to 

use the provided accessories and specified parts desig-
nated by our company.



(1) Install the indoor unit temporarily.

Attach the hanger bracket to the suspension bolt. Be sure 
to fix it securely by using a nut and washer from the left and 
right side of the hanger bracket. 

• (Refer to the picture below)

[ PRECAUTION ]

Since the unit uses a plastic drain pan, prevent welding 
spatter and other foreign substances from the air outlet 
during installation.

(2) Adjust the unit to fit between the walls.

(3) Check the unit is horizontally level.

CAUTION

• Make sure the unit is installed level using a level or a 

plastic tube filled with water. In using a plastic tube 
instead of a level, adjust the top surface of the unit to the 
surface of the water at both ends of the plastic tube and 
adjust the unit horizontally. (One thing to watch out for in 
particular is if the unit is installed so that the slope is not 
in the direction of the drain piping, this might cause leak-
ing.)

Mounting the remote controller

Refer to the “installation manual of the remote controller” 
supplied with remote controller.

Wall mounted type/floor standing concealed type

Use the installation mount on the rear of the unit for 
installation.
The unit requires minimum 100mm clearance (

F

) and 

clearance (

E

) on the bottom side for air intake and 

maximum 20mm clearance from the wall by using spacers 
(field supply)

CAUTION

Make sure no short circuit of air is caused when placing the 
unit directly under a windowsill.
