DIRT SENSOR
The electronic dirt sensor is a feature
which will detect particles as they pass
through the vacuum cleaner.
The dirt sensor indicators are located on
the front of the vacuum cleaner above the
dust bag cover.
D_t
Sensor
• When little or no dirt is present the dirt
sensor is green.
• With medium dirt concentration the dirt
sensor is amber.
• With heavy concentration the dirt
sensor is red and amber.
WARNING
Electrical Shock And Personal Injury
Hazard
Disconnect electrical supply before per-
forming maintenance to the unit. Failure
_odo so could result in electrical shock
_r personal injury from vacuum cleaner
suddenly starting.
OPERATION
As you vacuum, the amber and red
indicator lights will come on and stay on as
long as the sensor detects a high
concentration of particles passing through
the vacuum cleaner.
TO CLEAN DIRT SENSOR OPTICS
The dirt sensor optics consist of two optic
cells located inside the dust bag port.
Occasionally, it may become necessary to
clean the two optic ceils to assure
maximum performance.
It is recommended the optic ceils be
cleaned:
• When the red light stays on
continuously.
• When dirt or dust adheres to the
optic ceils.
• Whenever the dust bag is removed.
Optic Cells
To clean the sensor, wipe the optic cells
with a soft, dry cloth. Never use cleaners
or liquids as they can help speed the
recoating of the optic cells and make it
necessary to clean them much sooner than
normal. The dirt sensor area can be
reached by removing the dust bag.
