in following diagram; so center the main unit against the opening of ceiling,
ensuring that the respective opposite sides on all sides of the clearance between
them becomes identical.

2.3. Ceiling openings and suspension bolt installation
locations (Fig. 2-3)
Caution:
Install the indoor unit at least 2.5 m, 98-7/16 in. above floor or grade level.
For appliances not accessible to the general public.
• Make an opening in the ceiling 430 mm × 960 mm (17 in. × 37-7/8 in.) in size.
This functions as a check window and will be needed later during servicing.
• If the dimensions are not accurate, when the grille is installed there may be
gaps between it and the indoor unit. This may result in dripping water or other
problems.
• When deciding on placement, consider carefully the space around the ceiling and
make your measurements generous.
mm (in.)
• Ceiling types and building construction differ. Therefore you should consult with
the builder and decorator.
The centers of the ceiling opening and the indoor unit should be aligned.

• Using the installation template (top of the package) and the gauge (supplied as
an accessory with the grille), make an opening in the ceiling so that the main unit
can be installed as shown in the diagram. (The method for using the template
and the gauge are shown.)
• Use M10 (3/8") suspension bolts.
* Suspension bolts are to be procured at the field.
• After suspending the indoor unit, you will have to connect the pipes and wiring
above the ceiling. Once the location has been fixed and the direction of the pipes
has been determined, place the refrigerant and drainage pipes, the wiring for
the remote controller, and the wiring that connects the indoor and outdoor units
in their desired locations before suspending the indoor unit. This is especially
important in cases where the ceiling is already in existence.
