Where must a secondary drain line be located for it to serve as an alarm?

A secondary drain line that serves as an alarm must be located in a conspicuous place to ensure that any water discharge is readily visible. This visibility is crucial because it allows for immediate detection of potential problems, such as water leaks or blockages, which could indicate an issue with the primary drain line. By placing the secondary drain line where it can easily be seen, property owners and technicians can quickly respond to a situation that may lead to water damage or other complications, making it a key safety and maintenance feature in cooling and refrigerating systems.

While other locations such as near the unit or underneath it might provide some visibility, they do not guarantee prompt awareness or action in case of problems. Similarly, placing the drain line in the attic could lead to delayed detection due to its less frequently monitored nature. Thus, a conspicuous location enhances monitoring and maintenance efficiency.
