1. Rotate the Duo or UV-Aire ballast assembly counter-clockwise
until it stops. (See Figure 9)
2. Remove the ballast assembly and lamp from the mounting base.
(See Figure 10)
3. Remove the lamp from the lamp socket.
4. Install the replacement lamp into lamp socket. Do not handle the
lamp with bare hands. Oils on the hands tend to reduce lamp
intensity.
5. Wipe off the glass with the supplied alcohol wipe.
6. Position the ballast assembly power cord 90° to the viewport
hole on the mounting base. (See Figure 10)
7. Slide the lamp through the hole in the mounting base.

inspection and cleaning.
NOTE: Wear disposable, non-absorbent protective gloves prior to inspection procedure in case of accidental
breakage of glass.
1. We recommend inspecting and cleaning the lamp at least every 6 months. Frequency depends upon the
environment. Such as: the type of air fi lter, duration of use and replacement cycle.
2. To maintain maximum output intensity, replace the UV-Aire lamp annually. The lamp should operate
continuously for maximum lamp life and light effectiveness.
3.
Do not attempt to clean the catalytic honeycomb core with cleaning solutions. The catalyst is radiated with
short wave ultraviolet light during period of non-air fl ow and is self-cleaning. If there is build up blocking
the catalytic cells, sit the unit on end, on a fl at surface, with electrical enclosure facing up. Use low-pressure,
compressed air to blow the surface of the catalytic cells free of blockage.
