Clean the service port with a cloth piece. Ensure you don't clog the service port with debris or grim by wiping the port. You can use brake cleaner spray.

Now connect the home to the lower side service port - the hose should connect the nozzle on the gauze and the can. Take the hose length such that it is long to connect to the port with no need of placing the can in the engine bay.
