2. Safety Information

WARNING: Ultraviolet (UV-C) light is harmful to eyes and skin. Never look directly at an illuminated UV bulb. Avoid direct exposure of skin to UV-C light. Always disconnect power before servicing or replacing the bulb.

• Ensure the air purification system is completely powered off and disconnected from the electrical supply before handling the UV bulb.
• Wear appropriate personal protective equipment (PPE), including UV-protective eyewear and gloves, when handling the bulb.
• Do not touch the glass part of the bulb with bare hands. Oils from your skin can create hot spots and reduce the bulb's lifespan. If touched, clean with an alcohol wipe.
• Keep the bulb out of reach of children and pets.
• Dispose of old bulbs according to local regulations for hazardous waste, as they may contain mercury.

3. Setup and Installation

Follow these steps to safely install your replacement UV bulb:

1. Power Disconnection: Locate the power switch for your Lennox Healthy Climate UVC-24V air purification system and turn it off. Disconnect the system from its power source to prevent accidental activation.
2. Access Old Bulb: Open the access panel to the UV lamp compartment in your air purification system. Refer to your system's specific manual for instructions on accessing the bulb.
3. Remove Old Bulb: Carefully grasp the base of the old UV bulb. Gently twist and pull to remove it from its socket. Avoid touching the glass.
4. Inspect New Bulb: Before installation, visually inspect the new bulb for any damage, such as cracks or foggy spots. If any damage is observed, do not install the bulb.
5. Install New Bulb: Wearing gloves, align the four pins on the base of the new UV bulb with the corresponding slots in the socket. The raised ring on the base is designed to assist with proper alignment and installation. Gently push the bulb into the socket until it is firmly seated. Do not force it.
6. Secure Access Panel: Close and secure the access panel to the UV lamp compartment.
7. Restore Power: Reconnect the air purification system to its power source and turn the power switch on. The UV bulb should illuminate.

Note: Some UV bulbs may have a slightly different length than the original. Ensure the bulb fits securely within your system's mounting brackets and does not obstruct airflow or other components.

4. Operating Instructions

Once installed and powered on, the UV bulb operates continuously within your Lennox Healthy Climate air purification system. The bulb emits germicidal UV-C light at a peak wavelength of 254nm. This UV-C energy is effective in neutralizing airborne microorganisms such as viruses, bacteria, and mold spores as air passes through the system.

The UV light works to maintain a cleaner environment within your HVAC system and contributes to improved indoor air quality by reducing microbial growth on coils and other surfaces.

5. Maintenance

Regular maintenance ensures optimal performance and longevity of your UV bulb and air purification system.

• Bulb Replacement: The rated useful life of this UV bulb is 10,000 hours. For continuous air purification, it is recommended to replace the bulb annually, or as indicated by your air purification system's maintenance schedule, to ensure maximum germicidal effectiveness.
• Cleaning: If the bulb appears dusty or dirty, turn off and disconnect power to the system. Carefully remove the bulb (wearing gloves) and gently wipe it with a soft, lint-free cloth dampened with isopropyl alcohol. Allow it to dry completely before reinstallation.
• Handling: Always handle the UV bulb by its ceramic base, not the glass tube. Skin oils can leave residues that reduce UV output and bulb life.

6. Troubleshooting

If your UV bulb is not functioning as expected, consider the following:

• Bulb Not Illuminating:
  • Check if the air purification system is properly connected to power and turned on.
  • Ensure the bulb is securely seated in its socket. Gently re-seat it if necessary (after disconnecting power).
  • Inspect the bulb for visible damage, such as a "foggy spot" inside the glass, which indicates damage. A damaged bulb should be replaced.
  • Verify the system's ballast (power supply) is functioning correctly. If other bulbs in a multi-bulb system work, the issue might be with the specific bulb or its connection.
• Reduced Effectiveness:
  • The bulb may have reached the end of its effective life (approximately 10,000 hours). Even if it still glows, its germicidal output diminishes over time. Replace the bulb annually.
  • Dust or debris on the bulb can block UV light. Refer to the cleaning instructions in the Maintenance section.

If troubleshooting steps do not resolve the issue, contact customer support for further assistance.
