PLACEMENT CONSIDERATIONS
Outdoor Unit
Minimum Allowable Clearance and Service Access Requirements
Proper clearance for the outdoor unit coil is critical for proper unit operation. When installing the outdoor unit, consider service, inlet and
outlet and minimum allowable space requirements as illustrated in the diagrams on the following pages.
• Include enough space for airflow and for service access. If installing multiple outdoor units,
of one unit will blow into the inlet side of an adjacent unit.
• 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.
•
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.)
Outdoor Unit (9,000 to 24,000 Capacity) Service Access and Allowable Clearances
Specific clearance requirements in the diagram below are for (9,000 to 24,000 Btu/h capacities). The figure below shows the overall minimum
clearances that must be observed for safe operation and adequate airflow around the outdoor unit.
When placing the outdoor unit under an overhang, awning, sunroof or other "roof-like structure", observe the clearance requirements (as
shown in Cases 1 and 2) for height in relation to the unit. To have successful service access to the outdoor unit, see the figure below for
minimum spacing. When installing multiple outdoor units, see Cases 4 and 5 for correct spacing requirements.
