What is the minimum depth required for the pan?

The correct answer, indicating a minimum depth of 1-1/2 inches for the pan, is aligned with safety and efficiency standards outlined in the North Carolina Mechanical Code. The specification for a minimum depth is essential in ensuring that the condensate or any other liquids collected in a pan can effectively drain away without overflowing or causing water damage.

A depth of 1-1/2 inches provides sufficient capacity to accommodate typical condensation from HVAC systems, preventing premature filling and potential spillage. This standard depth also allows for proper airflow and drainage, which are critical in maintaining the efficiency and longevity of mechanical systems. Adhering to this requirement helps ensure that equipment operates safely and within code compliance, reducing the risk of leaks or structural issues.
