Installation Guide
Tools Needed:
- Adjustable wrench set
- Pipe thread sealant
- Air pressure gauge
- Level
- Voltage tester
- Foundation bolts
Step-by-Step Installation
- Select Location: Choose a clean, dry, well-ventilated area with adequate space for maintenance access and proper air circulation.
- Foundation Preparation: Ensure solid, level concrete foundation capable of supporting compressor weight and vibration.
- Electrical Connection: Connect to proper power supply per local electrical codes. Most models require 3-phase power connection.
- Air System Piping: Install proper size piping with drip legs and shutoff valves. Use thread sealant on all connections.
- Oil Check: Verify proper oil level in compressor crankcase before initial startup.
- Pressure Settings: Set cut-in and cut-out pressures according to application requirements.
- Initial Startup: Run compressor unloaded for 30 minutes to circulate oil and check for leaks.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor won't start | Power issue, pressure switch fault, thermal overload | Check power supply, reset overloads, verify pressure switch setting |
| Low pressure output | Air leaks, clogged filters, worn valves | Check for leaks, replace air/oil filters, inspect discharge valves |
| Excessive noise/vibration | Loose mounting, worn bearings, improper alignment | Tighten mounting bolts, check motor/compressor alignment |
| High operating temperature | Dirty cooler, low oil, restricted airflow | Clean cooler fins, check oil level, ensure proper ventilation |
| Excessive oil consumption | Worn seals, overfilling, wrong oil type | Check oil separator, verify proper oil level, use recommended oil |
| Frequent cycling | Air leaks, oversized compressor, control setting issues | Locate and repair leaks, adjust pressure settings, check controls |
Error Codes
