Maintenance and care
Exhaust filter change indicator
Some models are equipped with an ex-
haust filter change indicator (Reset but-
ton 7) which is designed for the
change cycle of an ACTIVE air clean or
an ACTIVE HEPA filter. The indicator
lights up after about 50 hours of opera-
tion which is equivalent to a year of av-
erage use.
The vacuum cleaner can still be used
with the exhaust filter indicator lit. How-
ever, the suction power will be reduced
as will the effectiveness of the filter if it
is not replaced.
If a SUPER air clean filter is being used,
the filter change indicator can be disre-
garded but should be reset when it
does light.
Resetting the filter change indicator
The filter change indicator (Reset but-
ton 7), must be reset each time the fil-
ter is replaced. To do this the vacuum
cleaner must be plugged in.
^ Press on the filter change indicator
light until it goes out. The display is
now back in the starting position.
