After the desired amount of time running the continuous shower, the process needs to be shut down. The process can transition directly to the recovery step, but first make sure that no unsafe conditions exist. Since this puts several pounds of butane into the recovery cylinder, the process is inherently dangerous. Take your time and make sure every valve is open or closed as it should be.
