had a quick question? im in the navy and im working on a york r-114 comp. and need to pull out all the liquid..i suggested we use the push pull methood but was told i didnt know what i was talking about by some ******* officer who thinks he knows everthing..anyway i know the refrigerant is used to cool the bearings but im not running the comp, but useing my own recovery unit to provide the pressure to help "push" the liquid out. now is this method a good idea or bad...its a large ton ac on a sub..i am new to the hvac world but iv read a lot of the books and the methood i have propsed seems to be the most logical????
