refrigerant exits the filter 70 and enters a visual moisture indicator sight glass 91 which enables a user to determine if there is more than a preselected level of moisture in the refrigerant such that the refrigerant is not suitable for reuse the refrigerant then exits the visual moisture indicator sight glass 91 and exits the device 50 via output port 82 the refrigerant may flow to a refrigerant recovery bottle tank or back into the source of the original used refrigerant the device 50 may also include a full level indicator switch within the storage bottle tank the full level indicator switch may be a spring assisted float that operates a sealed micro switch as the liquid reaches the full level the full level indicator switch is electrically connected to the device 50 via an electrical cord 44 and electrical plug 41 when the bottle tank reaches the full level the switch operates to shut down the device 50 this prevents over filling and over pressurizing the refrigerant storage bottle tank means other than the preferred embodiment of the full level indicator switch may be utilized without departing from the inventive concept an alternative may be a scale having a pressure sensitive switch the device 50 may also have a high pressure control and a low pressure control the high pressure control monitors the output of the compressor 54 and will shut down the device 50.
