Fundamentally, air is blown throughout a extremely cold liquid.
Verify for Leaks
Leaks are frequently straightforward to establish, but they are extremely hard to repair. Most car supply stores have a bright dye that can be injected into the a/c method, which will expose leaks. The can will have guidance for use.
There is also a valve that will expose the PSI (pounds for each sq. inch) inside the process. If the leak is pretty undesirable, the process will have very small tension or no strain at all. Nevertheless, do not examine for pressure by inserting everything into the valve nozzle. This is termed “venting,” and it is unlawful.
