Question

If a technician has a system where some R-502 was added to an R-22 system, what should the technician do?

1) Remove all refrigerant and flush the system with R-22
2) Run the system and see if it operates normally
3) Add more R-502 to the system
4) d. Consult the equipment manufacturer or a qualified refrigeration technician

Answer 1

If a technician accidentally adds R-502 refrigerant to an R-22 system, they should remove all refrigerant and flush the system with R-22. Adding more R-502 or running the system can lead to issues and damage. Consulting the manufacturer or a qualified technician is also recommended.

Step-by-step explanation:

If a technician has mistakenly added R-502 refrigerant to an R-22 system, the correct course of action would be to remove all refrigerant and flush the system with R-22. This is because R-502 is a different refrigerant than R-22 and they are not compatible. Mixing the two can lead to system malfunctions and potential damage. The technician should follow proper procedures to ensure the system is flushed thoroughly before adding the correct refrigerant.

Adding more R-502 to the system (option 3) is not a recommended solution, as it will further contaminate the system and exacerbate any issues. Running the system (option 2) may lead to poor performance and potential damage. Consulting the equipment manufacturer or a qualified refrigeration technician (option 4) is always a good idea in case there are specific instructions or considerations for the particular system.
