    PIPING HANDLING Piping Materials and Handling Keep Pipes Capped While Storing. Pipes used for the refrigerant piping system must include the specified thickness, and the interior must be clean. While handling and storing, do not bend or damage the pipes, and take care not to contaminate the interior with dust, moisture, etc.

    Failure to do so will cause significant performance degradation. Proper leak checks must be performed. Using isolation valves does not automatically void any LG product warranty, however, a limited warranty will be voided in whole or part if any field supplied accessory fail in any way that causes product failure.
  • Page 29 REFRIGERANT SYSTEM ENGINEERING Obstacles Figure 25: Installing Piping Above and Below an Obstacle. When an obstacle, such as an I-beam or concrete T, is in the path of the planned refrigerant pipe run, it is best practice to route the MINIMUM pipe over the obstacle.
  • Page 30 Pipe Sleeves at Penetrations LG recommends that all pipe penetrations through walls, floors, and pipes buried underground be properly insulated and routed through an appropriate wall sleeve of sufficient size to prevent compression of refrigerant pipe insulation and free movement of the pipe within the sleeve.

  • Page 31: Flaring And Brazing Procedures

    FLARING AND BRAZING PROCEDURES Flaring and Brazing Procedures One of the main causes of refrigerant leaks is a defective connection. For LG HVAC systems, the installer needs to know how perform both flared and brazed connections successfully. • During installation, it is imperative to keep the piping system free of contaminants and debris such as copper burrs, slag, or carbon dust.
