Minimum Clearance Requirements for Dual 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 dual fan outdoor units. Figure 4 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 specified clearance require-
ments 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 4 for minimum spacing. When installing multiple outdoor units, refer to the
appropriate clearance diagram for your installation. Outdoor unit fans draw air from the back of the unit and discharge out the front. Place
units back to back and front to front.
