Abstract
A method of clearing an orifice of a fluid conduit for refrigerant within an air conditioning service device. The method comprises establishing a pressure gradient between a branch of fluid conduit comprising the orifice and the external atmosphere and utilizing the pressure gradient to flush air through the orifice. The flow of air between the orifice and the fluid conduit is controlled to minimize introduction of unwanted air to the air condition service device.
