sensor is green.
• With medium dirt concentration the dirt
sensor is amber.

sendor is red and amber.
WARNING
Electrical Shock And Personal Injury
Hazard
Disconnect electrical supply before per-
forming maintenance to the unit. Failure
_o do 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 bin port.
Occasionally, it may become necessary to
clean the two optic cells to assure
maximum performance.
It is recommended the optic cells be
cleaned:
• When the red light stays on
continuously.
• When dirt or dust adheres to the
optic ceils.
• Whenever the dust bin is emptied.
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 bin.
