Installation Guide
Tools Needed:
- Torque wrench set
- Level
- Socket set (metric and standard)
- Multimeter
- Air pressure gauge
- Hoist or forklift (for positioning)
Step-by-Step Installation
- Site Preparation: Select a clean, dry, well-ventilated location with adequate space for maintenance access and proper airflow.
- Foundation Requirements: Ensure a solid, level concrete foundation capable of supporting the compressor's weight (approximately 1200 kg).
- Uncrating and Positioning: Carefully remove all shipping materials and position the compressor using appropriate lifting equipment.
- Electrical Connection: Connect to appropriate power supply (see specifications). All electrical work must comply with local codes and be performed by a qualified electrician.
- Air System Connection: Install proper air piping with minimum restrictions. Include isolation valve, check valve, and pressure relief valve in the discharge line.
- Cooling System Setup: Ensure adequate ventilation for air-cooled models or connect water cooling system as required.
- Oil System Check: Verify proper oil level and ensure all oil lines are properly connected and free of leaks.
- Initial Startup Procedure: Perform pre-start checks, then follow the step-by-step startup procedure outlined in Section 3 of this manual.
