UV100E ULTRAVIOLET SYSTEM HOW YOU CAN CHECK YOUR ULTRAVIOLET SYSTEM Your UV System is designed to prevent accidental contact with electrical voltage and with ultraviolet rays in the sealed unit⎯the ultraviolet lamp does not illuminate unless the base is mounted on your forced air system duct. It is recommended that every month you verify that your ultraviolet lamp is operating. View the bulb only through the lamp light indicator on the lamp handle. See Fig. 3. Do not attempt to look into the duct at the illuminated bulb(s). If the light is not on when you check your UV System, briefly push the reset button for one second. This brings the lamp on for 40 minutes (Air Treatment System) or for 30 minutes (Surface Treatment System). Pressing the reset button for five seconds resets all internal timers. Cycling power does not reset the internal timers. LAMP LIGHT INDICATOR LED CHANGE INDICATOR RESET BUTTON M22856 Fig. 3. Lamp light indicator, LED change indicator and reset button.

At 0% bulb life remaining, the bulbs continue to operate until catastrophic bulb failure (bulb burns out) but the kill rate becomes rapidly negligible. 69-1573-3 6
