What must condensate pumps located in uninhabitable spaces do in the event of a failure?

When condensate pumps fail, it is crucial for them to prevent the appliance from operating. This is to ensure safety and avoid potential damage or hazardous conditions. If a condensate pump fails, excess water can accumulate, leading to issues such as water damage, mold growth, or equipment malfunction, especially in environments where proper drainage is not available or effective.

By activating a mechanism to stop the operation of the appliance, you protect not only the mechanical system but also the occupants of the building from risks associated with water overflow. This is particularly significant in uninhabitable spaces, as these areas may not have the same level of supervision or immediate response as inhabited areas.

For instance, if an HVAC system continues to operate during a condensate pump failure, it can lead to increased humidity and potential flooding in that area, further complicating the situation. Therefore, ensuring that the appliance is prevented from operating until the issue is resolved is a critical safety measure.
