What is required where condensate storage or overflow could cause damage?

The requirement for an auxiliary pan with a drain pipe under equipment is crucial in scenarios where condensate storage or overflow could lead to significant damage. This auxiliary pan serves as a safety measure to catch any excess condensate that might leak or overflow from the primary system. In the event of a failure or blockage in the condensate removal system, the auxiliary pan helps prevent damage to the surrounding area and equipment by directing the condensate safely away from critical components or surfaces that could be adversely affected.

Having a drain pipe from the auxiliary pan ensures that collected water is properly directed away from the equipment and does not pose a risk of flooding or water-related damage. This design emphasizes the importance of preventative measures in mechanical systems, where uncontained water could lead to issues such as corrosion, electrical hazards, or even structural damage.

While other options may contribute to effective moisture management, they do not directly address the overflow risk in the same manner as the auxiliary pan with a drain pipe. For instance, a standard drip pan, while effective for minor drips, may not provide sufficient volume capture in the event of a larger overflow. Additional insulation on pipes or a condensate pump may address related issues but do not form the primary line of defense should a significant condensate
