  • Page 17 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. STATEMENT Precautions about brazing 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.
  • Page 18 When the external wire enters the interior of the unit through a waterproof cable connector, you need to separate the strong-current cable from the weak-current cable for cabling. For details, see the diagram. Inside the unit, wires should be fixed by using a cable tie through the overpass-shape component. The signal cables X1/X2 and P/Q/E must be fitted with a magnetic ring, and then all cables fixed on the overpass-shaped component by using a cable tie.
