Hello flavio if you really say that the pipes were open almost a week, how do you think that this will work without problems? Now you will have to take out a compressor again, turn it out and discard all the oil ((without throwing it in the environment)) Clean system with R141 and make a sweep and change filter since it sure got wet too and just there was a good vacuum and loaded with gas. Be very careful since the oil is moistened in about 15 minutes if it is POE and a little more if it is alkylbenzene. With this I want to tell you to do the following clean everything and assemble everything again but the compressor that is oil free once it is all welded and you tried not to leak just there you make a short 20 min short and just there with a Hose of the same manifold you get the oil that will suck through the same vacuum that has the compressor then continue with the normal vacuum and gas charges. regards
