Outdoor Unit Clearances
PLACEMENT CONSIDERATIONS
Minimum Clearance Requirements for Single-Zone Mega Systems
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 the single-zone Art Cool Premier wall mount systems. Figure 26 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 Figure 27) 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.
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.
