TROUBLESHOOTING TIPS
How do I reset the filter indicator light? I put in a new filter but the light is
still illuminated.
After changing the filter, RESET the filter indicator by holding down TIMER while the unit is
ON until the illuminated clean indicator light disappears.
Can I clean the filter?
The black mesh layer on the front of the filter, known as the Prefilter, captures large dust
and hair. This layer is held on with Velcro
®
-like strips. This Prefilter can be vacuumed in
place to maintain efficient operation of the unit. No other layers or parts of the filter can
be washed, cleaned, or otherwise reused. Please replace the filter regularly to maintain
optimal performance.
How can I tell if my UV lights have burnt out?
Turn on the UV lights by pressing UV and set the fan speed to 1. Make sure the room that the
unit is placed in is dark. Look through the top of the unit where the air blows out to see if there
is a blue glow. This glow is quite faint, so you may need to press the UV button on/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 order a replacement
UV light. UV lights are like normal light bulbs and will last approximately 9 to 12 months when
operated continuously.
