The OdorStop OS36 & OS72 UV Air Treatment System is designed to improve indoor air quality by preventing the growth of microorganisms such as mold, bacteria, and viruses on surfaces within the heating/cooling (HVAC) system. This device utilizes ultraviolet (UV) light to sanitize cooling coils, drain pans, and ductwork, thereby reducing airborne contaminants.

Function Description:

The core function of the OdorStop UV Air Treatment System is to emit UV-C light, which is effective at inactivating microorganisms. When installed in an HVAC system, typically above the cooling coil, the UV light continuously irradiates surfaces where moisture and organic matter can accumulate, preventing the proliferation of mold, bacteria, and viruses. This helps to maintain a cleaner HVAC system and improve the quality of the air circulated throughout the building. The OS36 model uses one UV lamp, while the OS72 model uses two, offering different levels of sanitization capacity.

Important Technical Specifications:

Models: OS36 and OS72
Power: 120V, 36W (for OS36, presumably 72W for OS72 with two bulbs)
UV Lamp Length: 16 inches (requires a minimum depth of 17 inches for installation)
Power Cord Length: 6 feet (requires a 120 Volt grounded power outlet within reach)
Installation: Designed for indoor installation on a closed duct system. Recommended mounting location is above the air conditioning cooling coil ("A Coil") if the HVAC system has air conditioning. If not, it can be installed on the supply air duct or, if necessary, the return air duct.
Safety Features: Equipped with LED indicator light(s) to verify proper operation. The OS36 has one LED, and the OS72 has two.
Materials: The unit is constructed for durability and includes a factory-installed gasket to ensure a tight seal with ductwork.

Usage Features:

Easy Installation: The system comes with a template for cutting holes in ductwork, sheet metal mounting screws, and an instruction manual. Tools required include a drill, 1/4" nut driver, 3/32" drill bit, and a 2 1/2" metal cutting hole saw.
Flexible Mounting: The unit can be mounted in any orientation, provided the LED indicator light(s) are visible.
Visual Operation Indicator: Green LED light(s) indicate that the unit and bulb(s) are functioning properly. A blinking LED indicates a faulty unit, while unilluminated LEDs suggest a power issue, off switch, faulty bulb(s), faulty fuse, or failed LED.
On/Off Switch: A simple on/off switch allows for manual control of the unit. The "on" position is indicated when the solid line on the switch is pressed down.
Safety Warnings: Emphasizes the importance of disconnecting power before servicing, never looking directly at illuminated bulbs, and wearing appropriate protection when working with sheet metal. UV light can be harmful to bare skin and eyes.

Maintenance Features:

Bulb Cleaning: Recommended every 3 months. Involves disconnecting power, unplugging the unit, allowing bulbs to cool, removing the unit from ductwork, and wiping the UV bulb(s) with a soft cloth dampened with glass cleaner. Fingerprints or dirt on the bulb(s) should be wiped away.
Bulb Replacement: Recommended annually. Similar to cleaning, it requires disconnecting power, unplugging the unit, allowing bulbs to cool, and removing the unit. New UV bulbs can be purchased from OdorStop. The bulb is removed by pushing a release button and installed by sliding the new bulb in until it snaps into place.
Fuse Replacement: If the LED light(s) are not illuminated and other troubleshooting steps fail, a faulty fuse may be the cause, requiring replacement.
No Serviceable Parts (Internal): The UV unit itself has no serviceable internal parts and should never be opened, except for bulb and fuse replacement. If the unit is faulty (indicated by blinking LEDs or a failed LED light), it must be replaced.
Warranty: A two-year limited warranty covers defects in materials and workmanship. It explicitly excludes fuses and UV bulbs, damage from improper use or installation, disassembling the unit, cosmetic damage, misuse, improper maintenance, and alterations.

The OdorStop UV Air Treatment System is designed for straightforward installation and maintenance, providing a proactive solution for improving indoor air quality by targeting microbial growth within the HVAC system. Users are strongly advised to adhere to all safety warnings and maintenance recommendations to ensure optimal performance and longevity of the device.
