How must the equipment and installation be positioned relative to the flood level rim of the condensate drain pan?

The correct response indicates that the equipment and installation must be positioned above the flood level rim of the condensate drain pan. This requirement is crucial for ensuring proper drainage and preventing any potential overflow or flooding from the condensate pan. By positioning the installation above this level, it allows for adequate gravity drainage of the condensate, minimizing the risk of water damage to the surrounding area or the equipment itself. This practice also helps ensure that any condensate that may accumulate can effectively flow away from the equipment without obstruction or backflow.

Maintaining this elevation is particularly important in HVAC systems, where condensate is generated during cooling operations. It helps to keep the system functioning correctly and contributes to overall system efficiency and reliability.
