Installation Guide
Tools Needed:
- Adjustable wrenches
- Level
- Screwdrivers (flat and Phillips)
- Pipe wrench
- Electrical test equipment
- Lifting equipment (for heavy components)
Step-by-Step Installation
- Site Preparation: Select a clean, dry, well-ventilated location with adequate space for maintenance access and proper airflow.
- Foundation Requirements: Install on a solid, level concrete foundation capable of supporting the compressor's weight (approximately 1800 kg).
- Electrical Connection: Connect to appropriate power supply (see specifications). All electrical work must be performed by a qualified electrician.
- Air System Connection: Install proper air piping with minimum pressure drop. Include isolation valves, check valve, and aftercooler if required.
- Cooling System: Ensure adequate ventilation and cooling air flow. Connect water cooling lines if using water-cooled model.
- Oil System Check: Verify proper oil level and install oil drain line if required for extended operation.
- Initial Startup: Perform pre-start checks, then initiate startup sequence following manufacturer's procedures.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor won't start | Power issue, emergency stop engaged, control fault | Check power supply, reset emergency stop, check control panel for faults |
| Low air pressure | Air leaks, clogged filter, system demand exceeds capacity | Check for leaks, replace air filter, verify system demand |
| High operating temperature | Dirty cooler, low oil level, ambient temperature too high | Clean cooler fins, check oil level, improve ventilation |
| Excessive vibration | Loose mounting, worn coupling, bearing wear | Check mounting bolts, inspect coupling and bearings |
| Oil consumption high | Oil leaks, worn seals, improper oil return | Check for leaks, inspect seals, verify oil return system |
| Frequent unloading | Air leaks, control setting incorrect, small receiver | Fix leaks, adjust pressure settings, check receiver size |
Error Codes
- E01: High Temperature - Check cooling system and oil level
- E02: Low Oil Pressure - Check oil level and pressure switch
- E03: Motor Overload - Check electrical connections and load
- E04: Phase Loss/Imbalance - Check power supply and connections
- E05: Sensor Fault - Check temperature/pressure sensors
- E06: Communication Error - Check control wiring and modules
