U3-130 lamp replacement and lifetime

The rated lamp life is about 1,000 hours. The rated lamp life is the average

life of the U3-130 lamps produced and tested (under the test conditions of our

company) for a long term, however, it may become shorter depending on

the conditions of usage.

After the lamp has been operating for 1000 hours or longer, the STATUS

indicator on the control panel will light and the “LAMP USAGE”icon

which shows hours of total U3-130 lamp usage will be displayed on the screen.

When this happens, turn off the unit and replace the lamp cartridge with a

new one. The unit will not turn on after 1100 hours. (It will go off if it is in

use.)
