Outdoor Units

Installation Space

Proper airflow through 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.

• Wall height at the front of the unit must be ≤ 59-1/16 inches.
• Wall height at the inlet side of the unit must be ≤ 19-11/16 inches.
• There are no height limitations for the walls at the sides of the unit.
• If the wall height at the front and inlet sides of the unit are higher than allowable limits,
additional space muct be included.
- Additional Space on the inlet side by 1/2 of h1.
- Additional Space on the front side by 1/2 of h2
- h2 = A(Actual height) - 59-1/16 inches
- h1 = B(Actual height) - 19-11/16 inches
