Installation Guide
Tools Needed:
- Torque wrench set
- Level
- Screwdrivers (flat and Phillips)
- Socket set
- Air pressure gauge
- Vibration pads
Step-by-Step Installation
- Site Preparation: Select a well-ventilated location with adequate clearance for maintenance on a solid, level concrete floor.
- Foundation Requirements: Ensure proper foundation with vibration isolation pads to minimize noise and vibration transmission.
- Electrical Connection: Connect to appropriate power supply (460V/3PH/60Hz) with proper circuit protection and grounding.
- Air System Connection: Install proper air piping with moisture separators, aftercoolers, and receiver tanks as required.
- Cooling System Setup: Connect cooling water supply (if water-cooled) or ensure adequate ventilation (if air-cooled).
- Oil System Check: Verify proper oil level and install oil filtration system as specified.
- Initial Startup: Perform initial startup sequence following manufacturer's commissioning checklist.
