Орнотуу жана орнотуу
Proper installation is crucial for the reliable operation of the pressure switch. Follow these steps carefully:
- Монтаждоо: 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.
- Электр байланышы: 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.
- Энергияга талаптар: This switch is designed for 12 Volts (DC) systems and has a current rating of 30 Amps. Ensure your electrical system meets these requirements.

Иштөө нускамалары
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.
