1. Introduction and Product Overview
The Field Controls UV-16/120 UV-Aire In Duct Air Purifier is designed to improve indoor air quality by utilizing ultraviolet (UV-C) light technology. This device is installed directly into your HVAC system's ductwork, where it neutralizes airborne contaminants such as bacteria, viruses, mold spores, and allergens as air passes through. This manual provides essential information for the safe and effective installation, operation, and maintenance of your UV-Aire system.

2. Safety Information
Please read all safety instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Electrical Hazard: This unit operates on 120 Volts. Ensure power to the HVAC system is disconnected at the circuit breaker before any installation or maintenance.
- UV Radiation Hazard: Do not look directly at the UV lamp when it is illuminated. UV-C light can cause severe eye and skin damage. Always ensure the lamp is off and cooled before handling.
- Installation: Installation should be performed by a qualified HVAC technician or electrician in accordance with all local and national electrical and building codes.
- Maintenance: Only use genuine Field Controls replacement parts. Refer to the maintenance section for bulb replacement procedures.

4. Setup and Installation
The UV-16/120 UV-Aire unit is designed for installation within the return or supply air duct of your HVAC system. Proper placement is crucial for effective air purification.
- Power Disconnection: Turn off all power to the HVAC system at the main electrical panel or circuit breaker. Verify power is off using a voltage tester.
- Select Installation Location: Choose a location in the ductwork that allows for sufficient airflow around the UV lamp and provides easy access for future maintenance (e.g., bulb replacement). Ensure there is at least 16 inches of clear space for the lamp.
- Cut Opening: Using the provided template (if applicable) or the unit's dimensions, carefully cut an opening in the ductwork for the main housing of the UV-Aire unit. Ensure the opening is clean and free of sharp edges.
- Mount the Unit: Insert the UV-Aire unit into the cut opening. Secure the unit to the ductwork using the provided mounting screws. Ensure a tight seal to prevent air leakage.
- Electrical Connection: Connect the unit's power cord to a dedicated 120 Volt power source, typically wired into the HVAC system's control circuit so it operates when the fan is running. Follow all local electrical codes. The unit features a safety disconnect for added protection.
- Install UV Lamp: If the lamp is not pre-installed, carefully insert the UV-C lamp into its receptacle on the unit. Ensure it is securely seated. Avoid touching the glass portion of the lamp with bare hands.
- Restore Power: Once installation is complete and all connections are secure, restore power to the HVAC system.
5. Operating Instructions
The Field Controls UV-16/120 UV-Aire In Duct Air Purifier is designed for continuous operation when your HVAC system's fan is running. It does not require daily user interaction.
- Automatic Operation: The unit is typically wired to operate in conjunction with your HVAC system's fan. When the fan is on, the UV lamp will illuminate, and air purification will begin.
- Indicator Light: The unit may feature an indicator light (often blue or green) to confirm that the UV lamp is operational. If this light is off, the lamp may need replacement or there may be a power issue.
- Button Control: While primarily automatic, the unit may have a simple button control for specific functions, such as a reset or a manual override for testing. Refer to the unit's labeling for specific button functions.
6. Maintenance
Regular maintenance ensures the continued effectiveness and longevity of your UV-Aire system.
- UV Lamp Replacement: UV-C lamps have a finite lifespan, typically 9,000 hours (approximately 1 year of continuous use). The effectiveness of the lamp diminishes over time, even if it still glows. It is recommended to replace the UV lamp annually to maintain optimal purification performance.
- Replacement Procedure:
- Disconnect power to the HVAC system at the circuit breaker.
- Allow the lamp to cool for several minutes.
- Carefully remove the old lamp by twisting and pulling it out of its receptacle.
- Dispose of the old lamp according to local regulations for fluorescent bulbs.
- Insert the new genuine Field Controls replacement lamp, ensuring it clicks securely into place. Avoid touching the glass with bare hands; use gloves or a clean cloth.
- Restore power to the HVAC system.
- Cleaning: Periodically inspect the UV lamp and the interior of the unit for dust or debris accumulation. If necessary, gently wipe the lamp with a clean, dry, lint-free cloth after disconnecting power and allowing it to cool. Do not use liquid cleaners.
7. Troubleshooting
If your UV-Aire system is not functioning as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| UV lamp is not lit | No power to the unit | Check circuit breaker. Ensure HVAC fan is running if wired to fan circuit. |
| UV lamp is not lit | Lamp has reached end of life | Replace UV lamp (refer to Maintenance section). |
| UV lamp is not lit | Faulty ballast | Contact a qualified technician for inspection and replacement of the ballast. (Note: Some users have reported ballast failure after extended use.) |
| Reduced air purification effectiveness | Lamp is old or dirty | Replace or clean the UV lamp. |
| Unit making unusual noise | Loose mounting or internal component issue | Ensure unit is securely mounted. If noise persists, contact a qualified technician. |
If the problem persists after attempting these solutions, contact Field Controls customer support or a qualified HVAC professional.
