warm air return, and must allow spreading of air throughout the room (near the center of the room)
• Clearance must be provided for the indoor unit from the wall and obstacles as shown in the figure.
Obstacles
• The installation place must be strong enough to support a load of 4 times the indoor unit weight to avoid
amplifying noise and vibration.
• The installation place (handing ceiling surface) must be levelled and the height in the ceiling is 350 mm
