Freon under pressure, much like LP and butane are liquid. At sea level pressure, freon becomes a gas. For freon to work in a refrigeration system, it must be able to transform from liquid to gas to liquid. So, to fill a system, it must be put into that system in liquid form. To do this, the bottle containing freon must be tipped, otherwise only freon the gas would be expelled.
