  2. Foundation Requirements: Ensure proper foundation with vibration isolation pads to minimize noise and vibration transmission.
  3. Electrical Connection: Connect to appropriate power supply (460V/3PH/60Hz) with proper circuit protection and grounding.
  4. Air System Connection: Install proper air piping with moisture separators, aftercoolers, and receiver tanks as required.
  5. Cooling System Setup: Connect cooling water supply (if water-cooled) or ensure adequate ventilation (if air-cooled).
  6. Oil System Check: Verify proper oil level and install oil filtration system as specified.
  7. Initial Startup: Perform initial startup sequence following manufacturer's commissioning checklist.
Warning: All installations must be performed by qualified personnel following local codes and regulations to ensure safe operation and maintain warranty coverage.

Troubleshooting

Problem Possible Cause Solution
Compressor won't start Power issue, safety switch tripped, controller fault Check power supply, reset safety switches, check controller diagnostics
Low air pressure Air leaks, worn rotors, intake filter clogged Check for air leaks, inspect airend, replace intake filter
High operating temperature Cooling system issue, low oil level, dirty cooler Check cooling fans, verify oil level, clean cooler fins
Excessive oil consumption Oil separator failure, oil leaks, worn seals Replace oil separator, check for leaks, inspect seals
Unusual noises Bearing wear, rotor contact, loose components Check bearings, inspect rotors, tighten all fasteners
Vibration issues Misalignment, worn mounts, unbalanced rotors Check alignment, replace mounts, inspect rotors

Error Codes

  • E01: High temperature shutdown - Check cooling system and oil level
  • E02: High pressure shutdown - Check pressure settings and relief valves
  • E03: Motor overload - Check electrical connections and load
  • E04: Low oil pressure - Check oil level and pump operation
  • E05: Sensor failure - Check temperature and pressure sensors
  • E06: Communication error - Check controller connections
