What should be verified about the performance of an Electric Static Precipitator (ESP) when interlocks are provided?

The verification of the performance of an Electric Static Precipitator (ESP) with interlocks is crucial for ensuring effective operation and safety in commercial cooking operations. Interlocks are designed to enhance the reliability and functionality of the ESP by preventing it from operating under conditions that could lead to unsafe situations or decreased performance.

Proven performance with no interruption of power exceeding two minutes is critical because the ESP relies on continuous operation to effectively remove smoke, grease, and particulate matter from the air. An interruption of power beyond this threshold could lead to an accumulation of contaminants, potentially creating a hazardous situation. If the ESP is not performing effectively due to power interruptions, it could allow harmful emissions to escape into the environment or even create fire risks due to the buildup of flammable materials.

Maintaining uninterrupted performance is essential for compliance with safety standards and regulations, as outlined in the NFPA 96. Therefore, verifying that there are no power interruptions exceeding the established limit ensures the ESP is functioning optimally and maintaining a safe environment in the cooking area.
