Outdoor Unit Clearances
PLACEMENT CONSIDERATIONS
Minimum Clearance Requirements for Single-Zone Art Cool Mirror 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 Mirror wall mount systems. Figure 14 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 14) 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.
In order to have successful service access to the outdoor unit, see Figure 14 for minimum spacing. When installing multiple outdoor units,
see Cases 4 and 5 in Figure 14 for correct spacing requirements.

Table 20: 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%.
