Abstract
A system for recovering at least two different and incompatible types of refrigerant that includes a compressor having an inlet for connection through first and second parallel inlet paths to equipment under service, and an outlet for connection through first and second parallel outlet paths to refrigerant storage containers. The first inlet and outlet paths terminate in connector fittings of a first configuration, and the second inlet and outlet paths terminate in connector fittings of a second configuration different from the first. Solenoid valves are associated with the inlet and outlet paths, and are actuated alternately so that the inlet and outlet paths are not simultaneously connected to the compressor. The connector fittings are mounted on a panel that has a sliding door for selectively exposing either but not both sets of connector fittings. The chance of misconnection and mixing refrigerant types is thereby reduced.
