Greetings companions! As I had already told you, I am getting started in this refrigeration. I recently started repairing my first fridge, but for this I need the help of someone with more experience. One of the things that emphasized me was to use alcohol (I don't remember which one) before loading the refrigerant into the system, warning me that if I didn't use it, the pipe would get clogged at any time. Browsing the web I found this article that warns that using alcohol in a refrigerant circuit is a death statement regarding the compressor What do you think? Is it convenient or not to use alcohol to prevent freezing of the pipes and remove moisture? What amount is used, what alcohol? Thanks in advance.

you perform vacuum and measure it with a vacuum gauge the water evaporates and the vacuum pump takes it out in the form of steam, you will realize that it is in that situation if the vacuum stabilizes for a while and then continue (unless the vacuum pump is not good and does not arrive) if a good vacuum is made and the dehydrator filter is changed it is not necessary to add any alcohol, if you have a good pump but do not reach the vacuum it is because there somewhere where air enters (a small loss) that air contains moisture and the system will always remain with humidity in those cases where the leak is undetectable or inaccessible there are several, products that are injected into the system already loaded and when they recirculate cover those leaks Alcohol is not a good practice. Regards

Hello, Christian, the theme of the alcohol used in the past has always brought controversies, I know by my own evidence that alcohol is extremely destructive for the windings of the motor compressor because it eats the insulating varnish and therefore short compressor, now knowing that, would you use alcohol? I clarified I had the same doubt so I did the test with a compressor seized first if it was mace the windings (they were fine) and immersed it in a can of empty paint with methyl alcohol and I covered it as they spent about 6 months and it was already completely short . I measured it to the months but maybe I have eaten it before so I only use R141 for cleaning and a vacuum pump to get moisture out. I clarify that the ethyl alcohol never tastes and I do not plan to use it just in case of doubt, and that which removes the moisture is a lie, what it does is prevent the humidity or water in the system from freezing at 0 ° C. Hopefully another person from your point of view. Regards comments and values responses. Ethyl alcohol = medicinal alcohol without color Methyl alcohol = industrial alcohol or burning alcohol usually blue-

Use tiner for cleaning the common alcohol is harm has a percentage of moisture water luck
