Configuración e instalación
Proper installation is crucial for the reliable operation of the pressure switch. Follow these steps carefully:
- Montaje: The pressure switch features a 1/8" NPT male port. Thread the switch into a compatible female NPT port on your air tank or manifold. Ensure a tight, leak-free seal using appropriate thread sealant (e.g., PTFE tape or liquid sealant) if necessary. Do not overtighten.
- Conexión eléctrica: The switch is equipped with 12 gauge wire leads. Connect these leads into your compressor's control circuit. VIAIR recommends using this pressure switch in conjunction with a relay to handle the compressor's current draw, protecting the switch from excessive electrical load. Refer to your compressor's wiring diagram for specific relay integration instructions.
- Requisitos de energía: This switch is designed for 12 Volts (DC) systems and has a current rating of 30 Amps. Ensure your electrical system meets these requirements.

Instrucciones de funcionamiento
The VIAIR 90223 Pressure Switch operates automatically to maintain desired air pressure within your system:
- When the air pressure in the system drops to 90 PSI, the pressure switch will automatically activate (turn on) the connected air compressor.
- The compressor will continue to run until the system pressure reaches 120 PSI, at which point the pressure switch will automatically deactivate (turn off) the compressor.
- This cycle repeats as needed to maintain pressure within the specified range.
This automatic operation ensures that your air system is always ready for use without constant manual monitoring.
Mantenimiento
The VIAIR 90223 Pressure Switch is a sealed unit designed for long-term, maintenance-free operation. However, periodic inspection is recommended:
- Inspección visual: Regularly check the switch and its connections for any signs of damage, corrosion, or loose wiring.
- Detección de fugas: Periodically check the NPT connection for air leaks, which can lead to excessive compressor cycling.
- Verificación de funcionalidad: Verify that the compressor turns on and off within the specified 90 PSI ON and 120 PSI OFF pressure range.
If any issues are detected, consult the troubleshooting section or contact VIAIR customer support.
Solución de problemas
If you encounter problems with your VIAIR 90223 Pressure Switch, consider the following:
- El compresor no se enciende:
- Check all electrical connections for tightness and proper wiring.
- Verify that power is supplied to the switch and compressor.
- Ensure the system pressure is below 90 PSI.
- If a relay is used, check the relay's functionality.
- Compressor Not Turning Off:
- Ensure the system pressure has reached 120 PSI.
- Inspect the switch for any physical damage or debris that might prevent it from disengaging.
- A stuck-closed switch can cause continuous compressor operation; this may indicate a need for replacement.
- Operación inconsistente:
- Check for air leaks in the system, which can cause rapid cycling.
- Verificar volumen establetage supply to the switch.
