Introducere
This manual provides essential instructions for the proper installation, operation, and maintenance of your VIAIR 90223 Pressure Switch. This device is designed to automatically control the operation of an air compressor by turning it on and off at pre-set pressure levels, ensuring efficient and safe system performance. Please read this manual thoroughly before installation and use.

Configurare și instalare
Proper installation is crucial for the reliable operation of the pressure switch. Follow these steps carefully:
- Montare: 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.
- Conexiune electrică: 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.
- Cerințe de alimentare: This switch is designed for 12 Volts (DC) systems and has a current rating of 30 Amps. Ensure your electrical system meets these requirements.

Instrucțiuni de operare
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.
Întreţinere
The VIAIR 90223 Pressure Switch is a sealed unit designed for long-term, maintenance-free operation. However, periodic inspection is recommended:
- Inspecție vizuală: Regularly check the switch and its connections for any signs of damage, corrosion, or loose wiring.
- Detectarea scurgerilor: Periodically check the NPT connection for air leaks, which can lead to excessive compressor cycling.
- Verificarea funcționalității: 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.
Depanare
If you encounter problems with your VIAIR 90223 Pressure Switch, consider the following:
- Compresorul nu pornește:
- 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.
- Operare inconsistentă:
- Check for air leaks in the system, which can cause rapid cycling.
- Verificați volumul stabiltage supply to the switch.
Dacă pașii de depanare nu rezolvă problema, este posibil să fie necesară asistență profesională.
