Maintenance

Regular maintenance ensures optimal performance and longevity of your WirelessAir system:

  • Inspect Air Lines: Periodically check all air lines for kinks, chafing, or leaks. Ensure connections are secure.
  • Compressor Filter: Inspect and clean or replace the air filter on the compressor as recommended in the full manual to prevent debris from entering the system.
  • Electrical Connections: Verify that all electrical connections are clean, tight, and free from corrosion.
  • System Mount: Ensure the EZ Mount bracket remains securely fastened to the vehicle frame.

Troubleshooting

If you encounter issues with your WirelessAir system, consider the following common troubleshooting steps:

  • No Power to Compressor: Check the main power fuse and all electrical connections. Ensure the vehicle battery has sufficient charge.
  • Controller/App Not Connecting: Verify the controller battery is charged (CR123A). Ensure Bluetooth is enabled on your mobile device and the system is within range. Try re-pairing the controller or app with the manifold.
  • Air Leakage: Listen for hissing sounds around air line connections and air springs. Use a soapy water solution to identify small leaks. Tighten connections or replace damaged components as needed.
  • Inaccurate Pressure Readings: Ensure the system is properly calibrated. If issues persist, consult the detailed manual or contact customer support.
