off several times to see if you notice a difference. If there is no glow, then the UV lights have

burnt out and need to be replaced. Visit www.AlenCorp.com or call 1-800-630-2396 to or-

der a replacement UV light. UV lights are like normal light bulbs and will last approximately

9 to 12 months when operated continuously.

Will the photocataylic oxidation filter work if the UV lights are turned off?

No. The interaction of UV-C light and a permanent titanium dioxide (TiO2) grid serves

as a photo catalyst to carry out hydrolysis (i.e. to break water into hydrogen and oxygen).

As TiO2 is exposed to UV light, it becomes increasingly hydrophilic. Thus, it can be used

reduce concentrations of airborne pollutants such as volatile organic compounds (VOCs)

into harmless elements.

Do I need to replace the photocatalytic oxidation filter?

No. This filter is permanent and does not need to be replaced. However, the UV lights will

need to be replaced as needed.

I have an issue not listed in this manual.
