What information is required on labels for thermal storage units?

Thermal storage units must have labels that include the manufacturer's name and address to ensure accountability and traceability. This information is crucial because it allows technicians and end-users to identify the source of the unit, which is important for any service-related inquiries or issues. If a problem arises with the unit, having the manufacturer's name readily available can facilitate warranty claims, service requests, or parts replacements, thereby ensuring better customer support and compliance with safety regulations.

While other options provide useful information, they may not be universally required on all labels for thermal storage units. Energy efficiency ratings, installation instructions, and warranty details may be important for consumer awareness and proper functioning but are not mandatory components of labeling according to the code regulations. The focus on the manufacturer's details emphasizes the importance of knowing the origin of the unit for proper maintenance and service.
