There have been numerous discussions aboutl;iquid charging versus vapor charging on this site. I won't get into that. Suffice it to say that I have dumped one hell of a lot of liquid into the suction side of equipment and have yet to damage a compressor.
I also know what compressors are more sensitive to liquid damage by way of their construction and am much more careful with them.
There are devices like the Kwik Charge, that are designed to flash that liquid for you. They are nice, but hardly necessary.
