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, en-
suring that the respective opposite sides on all sides of the clearance between
them becomes identical.

structors and interior decorators should be consulted for details.
(1) Extent of ceiling removal: The ceiling must be kept completely horizontal and the
ceiling foundation (framework: wooden slats and slat holders) must be reinforced
in order to protect the ceiling from vibration.
(2) Cut and remove the ceiling foundation.
(3) Reinforce the ends of the ceiling foundation where it has been cut and add ceiling
foundation for securing the ends of the ceiling board.
(4) When installing the unit on a slanting ceiling, interlock a pillow between the ceiling
and the grille and set so that the unit is installed horizontally.
