Always blow nitrogen into pipe which is brazed. Always use a non-oxidizing brazing materi-
al for brazing the parts and do not use flux. If not, oxidized film can cause clogging or dam-
age to the compressor unit and flux can harm the copper piping or refrigerant oil.
Note : The torch tip should be positioned at the opposite angle to shop the
correct way to apply heat on the pipe coupling.
