A method for removing a residual fluid contained in an external service hose (13) (15) of a refrigerant recharging/recovering machine (1) which comprises: a main hydraulic circuit (10) provided with an external connector (12) (14), connected to which is a first end of the external service hose (13)(15); and a refrigerant-recovery unit (9), which has an inlet terminal receiving the refrigerant and is configured to filter the refrigerant from additional fluids so as to supply it to a tank (6). The method envisages coupling the second free end (13b)(15b) of the service hose (13)(15) to the inlet terminal (29) of the refrigerant-recovery unit (9) and transferring the refrigerant from the tank for containing it to the refrigerant-recovery unit itself, through the main hydraulic circuit (10) and the service hose (13) (15). |
