Typical Applications
✔ HVAC systems (compressor control, air pressure monitoring)
✔ Industrial pumps & compressors (over/under pressure protection)
✔ Hydraulic & pneumatic systems
✔ Water treatment & filtration
???? Installation Notes
Mount vertically to avoid liquid ingress.
Use a pressure snubber in pulsating systems.
Check hysteresis setting to avoid rapid switching.
Test before full operation (adjust setpoint as needed).

Troubleshooting Tips
Switch not activating?
Check pressure setting (may be too high/low).
Verify wiring (NO/NC contacts correctly connected).
False tripping?
Adjust hysteresis (if available).
Check for pressure spikes or leaks.https://store.unigulfsupply.com/product/pressure-switch/
