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.
