SECTION IX
ULTRAVIOLET (U.V.) STERILIZER
The U.V. sterilizer contains a true U.V. sensor that continually monitors the sterilization power of the unit. When
the light emitting diode (L.E.D.) display of the sensor changes from green to yellow or red, it is time to clean the
quartz sleeve and U.V. probe. If the cleaning does not return the L.E.D. display to green, replace the U.V. lamp.
The average life of a lamp is one (1) year of continuous use. It is also recommended that the quartz sleeve and
U.V. sensor probe be cleaned once every four (4) months.
WARNING: NEVER LOOK DIRECTLY INTO THE UNPROTECTED PARTS OF THE UV
CHAMBER WHEN THERE IS POWER TO THE UV STERILIZER. SERIOUS
BURNS TO THE EYES and SKIN MAY RESULT. ALWAYS UNPLUG POWER
TO THE UV STERILIZER BEFORE WORKING ON IT.
