  • Page 28: General Refrigerant Piping System Information

    REFRIGERANT SAFETY STANDARDS / DEVICE CONNECTION LIMITATIONS Refrigerant Safety Standards ASHRAE Standards 15-2010 and 34-2010 address refrigerant safety and the maximum allowable concentration of refrigerant in an occupied space. Refrigerant will dissipate into the atmosphere, but a certain volume of air is required to safely dissipate the refrigerant. For R410A refrigerant, the maximum allowable concentration of refrigerant is 26 lbs./1,000 cubic feet (Addendum L modified the RCL to 26) of occupied spaces.

  • Page 29: Selecting Field Supplied Piping

    Always follow local codes when selecting and installing copper pipe and piping system components. Approved piping for use with LG Single Zone products will be marked “R410 RATED” along the length of the pipe. Piping wall thickness must meet local code requirements and be approved for a maximum operating pressure of 551 psi. When bending piping, try to keep the number of bends to a minimum, and use the largest radii possible to reduce the equivalent length of installed piping;...

    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 35 Pipe Sleeves at Penetrations LG recommends that all pipe penetrations through walls and floors 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. Use 4”+ curved sheet metal saddles between the bottom surface of the pipe and the bottom surface of the penetration.

  • Page 36: 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.
