General System Inspection
- Conduct thorough visual inspection for physical damage, corrosion, or oil leaks
- Record operating hours and compressor starts
- Check all safety signage and equipment labels for clarity
- Inspect all mounting hardware and vibration dampers
Compressor & Refrigerant System Checks
- Inspect compressor operation for abnormal noise or vibration
- Check refrigerant pressures and verify against specifications
- Analyze oil condition and replace if necessary
- Test oil heaters for proper operation
- Verify capacity control systems and slide valve function
Electrical System Checks
- Inspect electrical connections and panel components for wear or corrosion
- Verify motor amperage and thermal protection devices
- Test all control relays and starter contactors
- Ensure correct voltage and frequency operation
Water System Inspection
- Inspect chilled and condenser water flow, pressure, and temperature
- Verify operation of pumps, flow switches, and monitoring devices
- Check condition of water strainers, filters, and treatment systems
Heat Exchanger Cleaning & Evaluation
- Clean condenser and evaporator coils thoroughly
- Check approach temperatures and performance benchmarks
- Inspect water boxes and gasket seals
- Evaluate fouling conditions and schedule next cleaning
Safety & Protection Device Testing
- Test all safety interlocks, pressure/temperature sensors, and shutdown systems
- Verify correct settings for alarms and control limits
- Inspect pressure relief valves for integrity and compliance
Performance Monitoring & Documentation
- Review energy consumption data and performance logs
- Compare current performance with baseline benchmarks
- Document all inspection results and maintenance actions
- Schedule follow-up actions based on findings
