Remove and properly dispose of the system charge DO NOT vent the refrigerant or allow it to contact your eyes or skin 3 Remove the burned out compressor Use rubber gloves if there is any possibility of contacting the oil or sludge 4 To facilitate subsequent steps determine the type of burn out that occurred If the discharge line shows no evidence of sludge and the suction line is also clean or perhaps has some light carbon deposits the burn out occurred while the compressor was not rotating Contaminants are therefore largely confined to the compressor housing A single installation of liquid and suction line filter driers will probably clean up the system If sludge is evident in the discharge line it will likely be found in the suction line This indicates the compressor burned out will running Sludge and acid have been pumped throughout the system Several changes of the liquid and suction filter driers will probably be necessary to cleanse the system 5 Correct the system fault that caused the burn out Consult the factory for advice 6 Install the replacement compressor with a new capacitor and an oversized liquid line filter In a running burn out install an oversized suction line filter drier between the accumulator and compressor Thoroughly flush the accumulator with refrigerant to remove all trapped sludge and to prevent the oil hole from becoming plugged A standing burn out does not require a suction line filter
