Caution:
Install the indoor unit at least 2.4m (94-1/2inch) above fl oor or grade level.
• 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 fl uctuations 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 fi eld.
• Install securely, ensuring that there is no clearance between the ceiling panel &
grille, and between the main unit & grille.
