    firstly find out why its getting there i,e stuck solenoid valve or akv,then fix it, then the tricky bit either reclaim it or allow the compressor to pull it out try shutting the suction valve at the compressor,then crack it open ever so slightly and let the comp pull it back, just keep a eye on the oil level.

    Re: liquid in the suction line

    What type of system is it? Is it refrig or A/C? What is it operating at eg SST, cond temp etc. Is it dx or flooded. Is it a operating a chiller. What refrigerant and expansion device does it have. Does it have a header or accumulator? Many questions I know but it will help everyone to diagnose your problem more easily.

    Hi
    screws are faily tolerent with saturated suction gases, but liquid, not good. Something will break. More info on system application and refrigerant would be helpfull.

    Re: liquid in the suction line

    More information required. Probably an expansion valve issue. Has it got an accumulator on?
