2.2. Ceiling openings and suspension bolt installation
(inch)
locations (Fig. 2-2)
• Using the installation template 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,
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.

2.3. Installation of duct (in case of fresh air intake)
(inch)
(Fig. 2-3)
Caution:
Linkage of duct fan and air conditioner
ln case that a duct fan is used, be sure to make it linked with the air conditioner
when outside air is taken.
Do not run the duct fan only. It can cause dew drop.
Making a duct flange (prepared locally)
• The shape of duct flange shown left is recommended.
Installation of duct flange
• Cut out the cutout hole. Do not knock it out.
• Install a duct flange to the cutout hole of the indoor unit with three 4 × 10 mm tap-
ping screws which should be prepared locally.
Installation of duct (should be prepared locally)
• Prepare a duct of which inner diameter fits into the outer diameter of the duct flange.
• In case that the environment above the ceiling is high temperature and high humid-
ity, wrap the duct in a heat insulate to avoid causing dew drop on the wall.
Remove the drain pan insulation.
