locations (Fig. 3-2)
Warning:
• This unit should be installed in rooms which exceed the floor space specified
in outdoor unit installation manual.
Refer to outdoor unit installation manual.
• Install the indoor unit at least 2.5 m above floor or grade level.
For appliances not accessible to the general public.
• Refrigerant pipes connection shall be accessible for maintenance purposes.
• 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 is shown.)
* Before using, check the dimensions of template and gauge, because they
change due to fluctuations of temperature and humidity.
* The dimensions of ceiling opening can be regulated within the range shown in
Fig. 3-2; 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.
• Use M10 (3/8") suspension bolts.
* Suspension bolts are to be procured at the field.
• Install securely, ensuring that there is no clearance between the ceiling panel &
grille, and between the main unit & grille.
