Variable Air Volume Box – Procedure
Use this structured procedure to verify performance of VAV boxes, including actuator testing, damper movement, airflow response, and temperature control logic for optimal HVAC performance and energy efficiency.
Load Testing Procedure
- Notify occupants before initiating generator test
- Check and record fuel, coolant, and oil levels
- Simulate outage or use manual test mode
- Transfer load to generator (ATS or manual)
- Maintain load test for at least 30 minutes
- Record voltage, frequency, oil pressure, and temp
- Watch for vibration, noise, or smoke
- Return power to utility, verify retransfer
- Allow cool-down and document test results
Battery Maintenance Procedure
- Wear PPE and isolate battery circuit
- Clean all terminals with approved cleaner
- Check specific gravity (if applicable)
- Measure and log voltage of each cell
- Ensure proper electrolyte level
- Reconnect terminals securely and test charger
- Apply corrosion inhibitor after final check
Fuel System Procedure
- Check main and day tanks for sediment/water
- Inspect fuel filters and lines for damage
- Take fuel sample for visual clarity and odor
- Ensure fuel level sensors are functioning
- Verify venting system and containment area
Transfer Switch Inspection
- Open ATS panel and inspect terminals
- Test time delay and phase rotation settings
- Inspect cabinet for overheating or corrosion
- Perform manual transfer test (if allowed)
- Confirm indicator lamps and control relays
