True or False: If you are returning the refrigerant directly to the system after servicing, a graduated recharging cylinder cannot be used.

• A. True
• B. False
• C. Only in emergencies
• D. Only if the system is low on refrigerant

Answer: (B)

The statement that if you are returning the refrigerant directly to the system after servicing, a graduated recharging cylinder cannot be used is false.

In the context of refrigerant handling, a graduated recharging cylinder can indeed be used to accurately measure and control the amount of refrigerant being returned to the system. This practice allows for precision during the recharging process, ensuring that the system receives the correct amount of refrigerant based on its specifications.

Using a graduated recharging cylinder is particularly beneficial because it helps prevent overcharging or undercharging of the system, which can lead to operational inefficiencies or potential damage. Hence, when servicing a system, the use of a graduated recharging cylinder remains a feasible and often recommended option for returning refrigerant to ensure system health and compliance with best practices in refrigerant management.
