• Be sure to install indoor units on a level surface. Since the center of gravity of the unit is in the middle of
the unit, if the units are tilted they may fall.
Caution when connecting a duct
• Install a canvas duct between the unit and the duct.
• Use non-flammable parts for the duct.
• Provide sufficient heat/sound insulation to ducts and flanges.
• Avoid using ducts made of flexible aluminum or similar lightweight materials. They may vibrate and
