What should be the nature of the supports for equipment concerning condensate drain pans?

The nature of the supports for equipment concerning condensate drain pans should indeed be water-resistant. Drain pans are designed to collect any condensate from the equipment, which means they will be exposed to moisture regularly. Using water-resistant supports ensures that they will not deteriorate, warp, or degrade over time due to constant exposure to water. This is essential for maintaining the integrity of the support systems and the proper functioning of the drain pans, preventing potential leaks or failures that could lead to water damage or other issues.

While non-combustible supports can be important for certain applications, the specific concern with condensate is the repeated exposure to water, making water resistance a primary requirement. Flexible supports might allow some movement or adjustments, but they do not directly address the moisture issue. Portable supports are not typically relevant for fixed installations where drain pans need to be reliably supported. Thus, the emphasis on water-resistant materials ensures the longevity and effectiveness of the condensate drain system.
