Question

Prior to recharging a system with recycled refrigerant, the refrigerant should be checked for __________.

1) Leaks
2) Contaminants
3) Proper pressure
4) All of the above

Answer 1

The refrigerant should be checked for contaminants, leaks, and proper pressure before recharging a system with recycled refrigerant, making option 4) All of the above the correct answer.

Step-by-step explanation:

Prior to recharging a system with recycled refrigerant, the refrigerant should be checked for contaminants. It should also be checked for leaks and proper pressure. The correct answer is therefore option 4) All of the above. Checking for contaminants ensures that the refrigerant is pure and will not harm the system or reduce its efficiency. Checking for leaks is critical as it prevents the release of refrigerant into the atmosphere, which can be harmful to the environment and illegal under certain regulations. Ensuring proper pressure is necessary to verify that the refrigerant can be safely added to the system without causing overpressure or other issues.
