Question 34Refrigeration & AC - Assistant Engineer

The correct answer is C) do not attempt to recover any refrigerant and repair the leak before pulling a vacuum on the system. This is the correct answer because if the pressure in the refrigeration system is 0 psig, it indicates that the system is completely depressurized and has a significant leak. In this case, the proper procedure is to first repair the leak without attempting to recover any refrigerant. Recovering refrigerant from a system with a leak could lead to the release of refrigerant to the atmosphere, which is prohibited under environmental regulations. The other options are incorrect because recovering liquid or vapor refrigerant from a system with a 0 psig pressure would not be the appropriate first step. The leak must be repaired before attempting to pull a vacuum and recharge the system with refrigerant.
