Open MoldLights (without guard) work best when exposed to the largest volume of airspace or airflow possible. Continuous slow air movement over UV MoldLights helps expose most air in a room to control (kill) mold, mildew, bacteria (odors) and viruses. The closer an UV MoldLight is to the source of the problem the more effective it is.

MoldLight without UV guards can be used inside a cardboard box with top open to protect surrounding carpet, fabrics, paints and plastics. This is a temporary method of treating a space and protecting fadable materials.

Slow continuous air circulation must be available to create even distribution and avoid build up of ozone near the unit. Mold typically grows in dead air space. Testing may be required to find best location for unit placement. To test for airflow use tissue paper and check for air movement. Ozone required for humid climates and hidden water damage (in walls)and other areas.

Ozone Control: Designed with self-limiting ozone output.

May not be suitable for use with some over sensitive individuals. Then use when space is unoccupied.

On time, distance, room volume and temperature – controls actual trace ozone available. Use a timer, open window or cover lamp with aluminum foil to reduce ozone output if required for fine tuning an environment.

Duct Installation: Install bare lamp unit on return (filter side) only. Fan must be on for UV air treatment to work. Using power from fan motor automatically controls UV and ozone output (Z type). Do not wire to a variable speed motor. Use 1-1/2 inch (38mm) hole saw for each lamp used in duct (or as needed). Install lamp over the drip pan where possible.

Unoccupied Spaces: For heavy duty treatment, close all doors, windows and vents. Provide continuous air circulation for ozone to move around and penetrate through porous materials for treatment of hidden water damage or mold and bacteria growth inside walls or on surfaces. Turn ozone unit off 20 to 30 minutes before entering or using the space normally. NO people, plants or animals can be present during enclosed space (shock) treatments.

Ozone Time: 24 hours of treatment works for mild pollutant or mold situations. Extreme cases may take weeks of treatment to kill mold growth inside walls or thicker materials. Weekly, monthly or other term may work best for your situation. Each environment is different. Can be used to kill bacteria in refrigerators, HVAC coils, bedding, upholstery, basements, crawl spaces, closets, cat boxes, bathrooms. Can also be used in cars, boats and planes.

UV MoldLight {A18} A36 shown with reflector in the down/ direct position. Provides maximum disinfection properties. For use in unoccupied spaces.

If a UV MoldLight is in the down position turn power OFF if working within 24 feet (8 meters) even for a few minutes. Occasional walk by traffic is OK.

UV sun glasses can be used as eye protection if unit is on. Exposed skin must also be protected. Do not mount in direct position in public areas without automatic control.

Commercial Installation: A switch or sensor should be mounted near the entry of the area being treated where an MoldLight is permanently mounted. An additional caution label should be mounted on or near the switch. Additional caution labels are available on request.

Automatic Safety Control: Use our sensor switch model ASW where uninformed persons will be in the area. Or where safety is important. Sensor switch turns MoldLight off when motion is detected.

Temperature: Colder or high humidity spaces require longer exposure or higher wattage. General temperature range is 65°> 85°F (18°>30°C) for maximum efficiency. A18 may not start without ground or below 50°F (10°C)

Safety: Reddening of the skin (sunburn) and irritation of the eyes (conjunctivitis) are temporary conditions caused by direct over exposure to UV light. Effects may not be felt until several hours afterwards.

First Aid: For skin burn, treat as sunburn. Use pure aloe vera gel. Do not expose skin to sun until healed usually 3-5 days. For eye irritation keep person in a darkroom for 24 hours with no strong light. Place wet washcloth over eyes to relieve burning.

Ozone has a strong sent at first due to the reaction (oxidizing effect) of air and surfaces in the space being treated. MoldLights are self-limiting and will not produce excessive amounts of ozone. You can expect to reduce your chances of catching colds or flu in an ozone/ UV treated environment.

Color dyes may fade from prolonged exposures to UV light. May darken or produce haze on plastic surfaces.
