Ensure that the space at the back of the outdoor unit is a minimum of 11-13/16 inches, and
include a minimum of 23-5/8 inches at the right side of the unit for service.
If the outdoor unit discharge side faces a wall, include a minimum of 19-11/16 inches
between the outdoor unit and the wall. Install the outdoor unit so that the discharge port is
set at a right angle to the wind direction.
Outdoor Unit Service Access and Allowable Clearances
Appropriate airflow through the outdoor unit coil is critical for proper unit operation.
• Include enough space for airflow and for service access. If installing multiple outdoor units, avoid placing the units where the discharge of
one unit will blow into the inlet side of an adjacent unit.
• No obstacles to air circulation around the unit; keep proper distances from ceilings, fences, floor, walls, etc. (Install a fence to prevent pests
from damaging the unit or unauthorized individuals from accessing it.)
• If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that the discharge air of the outdoor unit isn’t restricted.
When installing the outdoor unit, consider service, inlet, and outlet, and minimum allowable space requirements as illustrated in the following
diagrams.
