The vapor refrigerant should be added to the low-pressure side of non-operating systems to ensure safe and effective integration. It's important to avoid the high-pressure side to prevent potential hazards. Always make sure the system is at an appropriate low-pressure level before charging. ;
Vapor refrigerant in non-operating systems should be added to the low-pressure side for safe and effective integration. Avoid using the high-pressure side due to safety risks. This method facilitates the proper circulation of refrigerant within the system.
