Installation Space Requirements
•
Position the unit on a horizontal surface. Any tilt in the unit should be 3° or less to the horizontal.
• Where a wall or other obstacle is in the path of outdoor unit’s intake or exhaust airflow, follow the installation space requirements
below.
•
For any of the below installation patterns, the wall height on the outlet side should be 47-1/4 inch (1200mm) or less.
• Secure as much installation space around the unit as the location allows, as more space will result in more efficient operation.

When installed as in the figure on the left, it is recommended to either
change the orientation of the outdoor unit outlet side or use the air direction
adjustment grille (sold separately).
Selecting a Location for Installation of
the Indoor Units
• The maximum allowable length of refrigerant piping, and the maximum allowable height difference between the outdoor and
indoor units, are listed below.
•
Refrigerant piping must be kept to a minimum.
The suggested shortest pipe length per room is 10ft (3m), in order to avoid noise from the outdoor unit and vibration.
(Mechanical noise and vibration may occur depending on how the unit is installed and the environment in which it is used.)
If the outdoor unit is positioned higher than the indoor units.
If the outdoor unit is positioned lower than
one or more indoor units.
