Cut the pipe in the same procedure as that for suction

①
Suction pipe
Before disconnection work, be sure to check the residual
pressure in the unit is 0MP a.
(It is very dangerous to brazing pipe too hastily.)
It is better to disconnect the pipe by cutting, because the
pipe is thicker and the insertion depth of pipe is deeper.
If research is required, cut the pipe as nearer as the
brazing point in order to leave longer pipe on compressor
side.
