      • Install nuts on both sides of the panel and gently tighten with a wrench to ensure the connector is securely fastened
      • Cut the end of the PU tube straight, ensuring a perpendicular cut
      • Push the PU tube into one end of the bulkhead union; a "click" sound indicates proper installation
      • Repeat the above steps to install the tube on the other end
      • To disassemble a tube, press the release sleeve on the push-in port and pull out the tube
    3. Installation Check

      • Check for air leakage at all connection points
      • Gently pull each tube to confirm secure connections
      • Ensure the entire connection system is stable and reliable
