When is it against EPA regulations to use system-dependent recovery equipment?

Using system-dependent recovery equipment is against EPA regulations when the appliance contains over 15 pounds of refrigerant. System-dependent recovery equipment relies on the compressor of the refrigeration system itself to remove refrigerant from the system. If the appliance contains more than 15 pounds of refrigerant, using this type of equipment can lead to incomplete recovery. The EPA requires that technicians use self-contained recovery devices for larger systems to ensure the refrigerant is properly captured and to prevent emissions into the atmosphere, which contributes to environmental harm.

Technicians are expected to apply the appropriate recovery methods based on the amount of refrigerant in the system to abide by these regulations, create safe working environments, and minimize potentially harmful emissions. Understanding these limits helps ensure compliance with environmental regulations and promotes the proper handling and disposal of refrigerants.
