Brazing the Pipe

• Make sure that there is no moisture inside the pipe.
• Make sure that there are no foreign materials and impurities in the pipe.
• Make sure that there is no leak.
• Be sure to follow the instruction when brazing the pipe.
The use of Nitrogen gas
1) Use Nitrogen gas when brazing the pipes as shown
in the picture.
2) If you do not use Nitrogen gas when brazing the
pipes, oxide may form inside the pipe. It can cause
the damage of the compressor, valves.
3) Adjust the flow rate of the Nitrogen gas with a
pressure regulator to maintain 0.05m3/h or less.
