3.2. Ceiling openings and suspension bolt installation
locations (Fig. 3-2)
• 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.)
* 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
following diagram; so center the main unit against the opening of ceiling, ensur-
ing 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.
