ADVANCED LEAK DETECTION Leakage that avoids detection by the basic field test (SL) must be determined by Nitrogen pressurization (PDL), run-vibration (VDL), or by adding heat (TDL). Lastly, even if you determine the system will not maintain a vacuum, it does not indicate where the leak is and additional leak test methods will be required. With this nitrogen leak test procedure, the HVAC technician first removes any remaining freon or Puron and pumps compressed nitrogen into the refrigeration system. IMPORTANT: DO NOT exceed the recommended pressures (use a pressure regulator) and DO NOT operate the air conditioning system with oxygen free nitrogen (OFN) in the refrigerant circuit.
