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.
