As shown in Fig.16 and Fig.17, open the outermost soundproof cotton and
place a fire barrier between compressor and straight pipe. Use a soldering gun to
unsolder straight pipe 1 and straight pipe 2. Install connection pipe 1 and connection
pipe 2 to the corresponding position and then seal the apertures with welding rod.
First weld the liquid side connection pipe and then weld the gas side connection pipe.
During welding, it’s necessary to use wet gauze to wrap up the two cut-off valves.
Make sure the flame won’t burn the soundproof cotton or other components.
