Installation Guidelines
• Where a wall or other obstacle is in the path of outdoor unit’s intake or exhaust airflow, follow the
installation guidelines below.
• For any of the below installation patterns, the wall height on the exhaust side should be 47-1/4 inch
(1200mm) or less.
* Be sure to add the proper amount of additional refrigerant.
Failure to do so may result in reduced performance.

Level mounting base
(available separately)
If there is the danger of the unit falling
or overturning, fix the unit with
foundation bolts, or with wire or other
means.
If the location does not have good
drainage, place the unit on a level
mounting base (or a plastic pedestal).
Install the outdoor unit in a level
position. Failure to do so may result in
water leakage or accumulation.
