What information must be labeled on an automatic damper?

Automatic dampers must be labeled with specific information to ensure proper identification, maintenance, and compliance with safety standards. The labeling typically includes the name of the installer and the date of installation. This is essential because it allows for tracking the installation timeline and accountability regarding who completed the installation. If issues arise, maintenance personnel and building operators can easily identify the installer for any follow-up or service needs.

Having the installer's name on the label also facilitates communication for any warranty claims or service calls that may arise later. The date of installation is crucial to evaluate the lifespan and required maintenance of the equipment, as various mechanical components have specific service intervals based on their age and usage.

In contrast, other options may include important identifiers, but they don't capture the same practical necessity for accountability and follow-up that the installer's name and installation date provide. For example, while the manufacturer's name and model number can provide useful product information, they don't necessarily indicate who installed it or when, which are the key details needed for ongoing management and upkeep of the damper.
