i wana throw this out there and see what everyone thinks,

I attended a site six months ago to fit a compressor on behalf of a manufacture(Samsung) this site has three imported cooling only splits serving a computer room ,they have had problem after problem with gas leaks from day dot due to the very poor design off these imports they have no LP\HP and the poor Coopland scroll compressor starts with such a bang its fracturing the suction pipe ,so after changing all three internal pipe guts to solve this I changed to comp but removed the direr after doing an acid test on the oil and finding it clean so may way off thinking why do I need it in, the less to go wrong the better with theses, and ive suggested that manual reset LP switches be fitted.was I right to remove it? They think not but it over to you guys
