What items must be included on the primary label of a radon mitigation system?

The primary label of a radon mitigation system is essential for providing vital information to homeowners and future service providers regarding the system's setup and maintenance. The inclusion of the installation date is critical as it indicates when the system was put in place, which is important for tracking the system's age and performance over time.

Additionally, the description of the system monitor is crucial because it informs users about the specific monitoring equipment used to assess indoor radon levels. This is important for understanding how to properly interpret the readings and manage radon exposure.

Including the installer’s contact information on the label facilitates communication for any maintenance or troubleshooting needs. Homeowners may require assistance, have questions about the system, or need to schedule follow-up testing, and having direct access to the installer helps ensure that the system remains effective over time.

Overall, this combination of information on the primary label supports the ongoing management of radon levels in a home, promoting safety and awareness for future occupants or maintainers of the system.
