How many data plates must an ATU unit have?

1. One

2. Two

3. Three

4. Four

The correct answer is: Two

An Aerobic Treatment Unit (ATU) is required to have two data plates for compliance with regulations and to provide essential operational information. These data plates typically have crucial information regarding the unit, including the manufacturer’s details, operational guidelines, and specific maintenance requirements. Having two data plates ensures that there is redundancy in the information provided, which can be beneficial for installation, inspection, and maintenance processes. One plate may be dedicated to the basic operational instructions and the other to critical safety information and specifications, enhancing clarity for the installer and maintenance personnel. The presence of both plates is vital for ensuring the proper functioning of the unit and for maintaining compliance with health and environmental regulations. This requirement is set to ensure that the information is readily accessible, even if one plate were to be damaged or become unreadable over time.
