Visual System Inspection
- Inspect entire system for leaks, corrosion, and physical damage
- Clean debris from mechanical rooms and chiller surroundings
- Review weekly runtime and start-stop logs
- Verify proper labeling and accessibility of safety devices
Compressor & Refrigerant Check
- Check compressor for abnormal noise, heat, or vibrations
- Monitor refrigerant pressures and temperatures
- Inspect oil levels and heaters (for oil-lubricated models)
- Perform refrigerant leak checks using detection equipment
Water System Monitoring
- Verify water flow rates and pressure differential readings
- Inspect pumps for operational noise and vibrations
- Check cooling tower operation and water treatment chemical levels
- Clean strainers and verify flow switch functionality
Heat Transfer Components Review
- Inspect heat exchangers for fouling and blockage
- Document approach temperatures for condenser and evaporator
- Check coil surfaces for scaling and clean as necessary
- Ensure refrigerant circuits are balanced and flowing correctly
Safety System Testing
- Test all safety switches, pressure relief valves, and interlocks
- Verify emergency shutdown system activation procedures
- Inspect alarm systems and communication link status
- Review documentation for safety compliance and updates
Performance Documentation
- Record energy efficiency metrics (e.g., kWh per ton)
- Trend temperature and pressure data for performance consistency
- Note any deviations or unusual readings for corrective actions
- Update weekly maintenance logs and submit reports for review
