PlaCement ConSiderationS
outdoor unit
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.
Minimum 11-13/16
