What is required for condensate downflow systems?

In condensate downflow systems, the presence of blockage detectors in the primary pan is critical for ensuring the system functions effectively and safely. These detectors are essential because they monitor for any obstructions that may impede the flow of condensate. If there is a blockage, it can lead to water accumulation, which poses risks such as overflow, potential water damage, or even mechanical failure in associated equipment.

The role of these detectors is to provide timely alerts about any issues, allowing for prompt maintenance actions to be taken before serious problems arise. This proactive monitoring helps maintain the integrity and efficiency of the condensate system, thereby ensuring reliable operation.

While other options may seem relevant, they do not directly address the critical safety and operational monitoring that blockage detectors provide within the context of condensate downflow systems.
