Please note that the lamp has an approximate life of one year. Although the lamp will continue to operate
long past one year, the UV output continually decreases after one year and may no longer provide adequate

The audible alarm cannot be silenced.
Please note that if this condition occurs and you are on a non-municipal water source, you should immediately
