Required Outdoor Unit Clearances
Minimum Clearance Requirements for Single Fan Outdoor Units
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 below.
Specific clearance requirements in the diagram below are for single fan outdoor units. Figure 3 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 in Figure 3) for height in relation to the unit. This clearance ensures that heat radiation from the condenser is not
restricted around the unit.
Adhere to all clearance requirements if installing the unit on a roof. Be sure to level the unit and ensure that the unit is adequately anchored.
Consult local codes for rooftop mounting requirements. To have successful service access to the outdoor unit, see Figure 3 for minimum
from the back of the unit and discharge out the front. Place units back to back and front to front.

Table 4: Outdoor Unit Service Access and Allowable Clearances Diagram Legend.
Do not place the unit where animals
and/or plants will be in the path of the warm
air, or where the warm air and/or noise will
disturb neighbors.
If the outdoor unit is installed between standard and minimum clearances, capacity decreases approximately 10%.
