Installation Guide
Tools Needed:
- Torque wrench set
- Level
- Screwdrivers (flat and Phillips)
- Pipe wrench
- Tape measure
- Air pressure gauge
Step-by-Step Installation
- Select Installation Site: Choose a well-ventilated area with solid, level concrete foundation and adequate clearance for maintenance access.
- Prepare Foundation: Ensure foundation can support compressor weight (approximately 1200 kg) and is vibration-isolated if required.
- Position Compressor: Carefully position compressor unit using appropriate lifting equipment, ensuring proper alignment.
- Connect Power Supply: Connect to appropriate 3-phase power supply (see specifications) using proper gauge wiring and circuit protection.
- Install Air Lines: Connect main air discharge line using proper pipe sizing and support brackets. Include isolation valve.
- Connect Cooling System: Install water cooling lines if applicable, ensuring proper flow rate and pressure requirements.
- Install Air Receiver: Connect and secure air receiver tank according to local pressure vessel regulations.
- Initial Startup: Perform pre-startup checks, fill with recommended lubricant, and conduct initial test run.
