ENGLISH
When conducting welding, you must pass nitrogen through at about 0.02 MPa (0.2 kg/cm
2
).
Before proceeding to weld, you must remove all the air from inside the pipe using nitrogen.
Failure to use nitrogen results in the occurrence of oxidation inside the pipe, leading to the
malfunction of the compressor and blocking of the strainer.
WARNING
• While welding, always be careful that no refrigerant leaks.
• When refrigerant combusts, it creates a toxic gas that is harmful to the body.
• Do not conduct welding in an enclosed area.
• After welding a pipe, be sure to test for any leakage.
