🔍 Key Concepts

• Basic leak response sequence in a mechanical refrigeration system • Relationship between finding a leak and recovering or charging refrigerant under EPA/USCG environmental rules • Physical signs of a leak such as oil residue at leak points

💭 Think About

• Before you can decide whether to recover, evacuate, or charge the system, what critical information do you still need about the exact location of the problem? • In what order do safe and environmentally compliant refrigeration practices usually occur: repair/locate leak vs. adding or fully removing refrigerant? • Which action from the choices would help you confirm and localize the leak you already suspect, so that any later repair or system service is effective?

✅ Before You Answer

• Make sure the suspected leak is positively located before deciding on recovery, evacuation, or charging steps • Confirm that you never add refrigerant to a leaking system as a first response • Ensure your first step directly supports identifying the leak source so that proper repair and compliant handling of refrigerant can follow
