(2) Make the ceiling opening needed for installation where applicable. (For existing ceilings)

Refer to the paper pattern for installation (5) for ceiling opening dimensions.

Create the ceiling opening required for installation. From the side of the opening to the casing outlet, 
implement the refrigerant and drain piping and wiring for remote controller (unnecessary for wireless 
type) and indoor-outdoor unit casing outlet. Refer to “6. REFRIGERANT PIPING WORK”, “7. DRAIN 
PIPING WORK” and “8. ELECTRIC WIRING WORK”.

After making an opening in the ceiling, it may be necessary to reinforce ceiling beams to keep the ceiling 
level and to prevent it from vibrating. Consult the builder for details.

(3) Install the suspension bolts.

(Use either a M8~M10 size bolt)
Use a hole-in anchor for existing ceilings, and 
a sunken insert, sunken anchor or other field 
supplied parts for new ceilings to reinforce 
the ceiling to bear the weight of the unit. 
Adjust clearance (50 – 100mm) from the 
ceiling before proceeding further.

NOTE

All the above parts are field supplied.

5. INDOOR UNIT INSTALLATION

Installing optional accessories (except for the decoration panel) before installing the indoor unit is 
easier. However, for existing ceilings, install fresh air inlet component kit and branch duct before 
installing the unit.

As for the parts to be used for installation work, be sure to use the provided accessories and specified parts 
designated by our company. 

(1) For new ceilings
(1-1) 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 (3) from the upper and lower sides of the hanger bracket.
The washer fixing plate (7) will prevent the washer from falling.

(1-2) 

Refer to the paper pattern for installation (5) for ceiling opening dimension.

Consult the builder or carpenter for details.

The center of the ceiling opening is indicated on the paper pattern for installation.
The center of the unit is indicated on the triangular mark to the unit bottom and on the paper pattern for 
installation.

Fix the paper pattern to the unit with screws (6) (×4).

Ceiling height is shown on the side of the paper pattern for installation (5). Adjust the height of the unit 
according to this indication.
