🔍 Key Concepts

• Behavior of water as a secondary refrigerant and risk of freezing when refrigerant is removed • What happens to temperature and pressure in the system as the primary refrigerant is pumped out • Protection of system components (piping, coils, heat exchangers) from damage during pump-down or recovery

💭 Think About

• When you remove the primary refrigerant, what happens to the temperature of any water that remains in those coils or heat exchangers? Could it freeze? • Which procedure(s) directly prevent mechanical damage to equipment during refrigerant removal, and which are more about normal operating efficiency or contamination control? • Think about what would cause immediate damage (like burst tubes or coils) versus what would be more of a maintenance or quality concern over time.

✅ Before You Answer

• Identify which option(s) directly prevent freeze damage to coils or piping during refrigerant removal. • Check which choices are about operational contamination versus physical safeguarding of equipment. • Verify whether leaving refrigerant in the system is ever a recommended method for protecting equipment during pump-down.
