In the Healy Phase II Enhanced Vapor Recovery (EVR) System, the operation of the VP-1000 motors is designed to mitigate vapor emissions effectively by utilizing the ambient temperature as a key factor. The correct choice indicates that the motors will activate when the ambient temperature drops below 40 degrees Fahrenheit.

This threshold is established to ensure that the system can effectively recover vapors, especially during colder conditions, when fuel volatility may decrease and the likelihood of vapor formation is reduced. By running the motors at this temperature, the Healy system helps maintain proper vapor recovery efficiency.

The choice of 40 degrees as the activation temperature strikes a balance between the need for ensuring operational effectiveness in colder conditions while preventing unnecessary wear or energy consumption from the motors running at higher temperatures when vapor recovery is less critical. Understanding this specific operational temperature helps in both installation and troubleshooting aspects of the Healy system, ensuring compliance with environmental regulations and efficient fuel handling.
