Complete Guide: How to Vacuum and Release Gas in a Split Air Conditioner Correctly

 Correctly performing the vacuum and releasing the gas in the split air conditioner are crucial steps during the installation or maintenance of the device. These procedures ensure that the system operates efficiently and reliably, providing a comfortable environment. In this text, we will cover how to perform the vacuum and gas release correctly, presenting the tools and equipment necessary to carry out these processes successfully.


To start the process, it is essential to have specific tools, such as a vacuum pump, manifold, hoses, service valves and refrigerant gas cylinder. First, connect the vacuum pump to the manifold and air conditioning system, ensuring that all valves are closed. Next, the vacuum pump valve is opened and the system is allowed to operate for an appropriate period of time, generally between 30 minutes and 1 hour, to remove all air and moisture from the system.

After the vacuum has been successfully performed, it is time to release the refrigerant gas into the system. To do this, the refrigerant gas cylinder is connected to the manifold and the air conditioning system. The cylinder and manifold valve opens, allowing refrigerant gas to flow into the system. During this process, it is important to monitor the system pressure and ensure that the correct amount of refrigerant gas is added, according to the manufacturer's specifications.
It is crucial to follow all safety standards when carrying out these procedures, including the use of personal protective equipment, such as gloves and protective glasses. Also, make sure the room is well ventilated to avoid inhaling toxic gases. At the end of the process, a careful inspection is carried out to ensure that there are no leaks in the system and that all connections are secure and sealed correctly.

In conclusion, correctly performing the vacuum and releasing the gas in the split air conditioning are essential steps to guarantee the efficient and reliable operation of the system. By following the correct procedures and using the appropriate tools and equipment, it is possible to execute these processes successfully, providing a comfortable and safe environment. Always remember to prioritize safety when carrying out these tasks and, if necessary, seek guidance from a qualified professional to ensure quality work.
