The lubrication assembly is operably coupled to the compressor, the condenser and the evaporator and is formed to define first-third pathways via a three-way valve and a fourth pathway. The first pathway is configured for pumping refrigerant through the chiller, the second pathway is configured for pre-storing refrigerant in the chiller, the third pathway is configured for removing refrigerant from the chiller and the fourth pathway is configured for charging refrigerant into the chiller. The controller is configured to control the lubrication assembly to selectively engage one of the first-fourth pathways.
