Question: 1 / 400

The minimum distance from the adjoining ground level should be at least how many inches above?

3 inches

6 inches

2 inches

The minimum distance from the adjoining ground level that is required to be maintained for HVAC equipment, especially for air conditioning systems or heat pumps, is typically set at 2 inches. This height is crucial because it helps prevent water accumulation around the unit, which might lead to corrosion or damage to the electrical components. Maintaining this elevation also assists in ensuring adequate airflow, as debris and vegetation that might obstruct the condenser's air intake can be kept at bay, enhancing the system's efficiency and longevity.

While other options suggest greater heights, the standard code requirements generally recognize 2 inches as sufficient for the specified purposes, balancing practical concerns and regulatory compliance.
