Use screw thread to connect the pipe on the water system side. Tighten the pipe to avoid water leakage.
Brazing is required on the refrigerant side.

In the event of brazing, please use nitrogen for sweeping. This can prevent the occurrence of oxidation inside pipes.
Oxidation will have adverse effects on the valves and compressors in the cooling system, and may hamper normal
operations.
Use the pressure relief valve to set the nitrogen pressure to 0.02 MPa (a pressure that can just be felt by the skin).
Do not use antioxidants when brazing pipe connectors. Residues will block pipes and damage equipment.
Do not use a flux when brazing copper refrigerant pipes. Use copper-phosphorus alloys (BCuP) where no flux is required.
Flux is harmful to the cooling pipe system. For example, if a chlorine-based flux is used, pipes will be corroded. Especially
when the flux contains fluorine, the flux will degrade the frozen oil.
