When To Change The Exhaust Filter - Miele S 556 Operating Instructions Manual

When to change the exhaust
filter
The built-in exhaust filter change in-
dicator (Re-set button 7) is de-
signed for the change cycle of an
ACTIVE air clean or an ACTIVE
HEPA filter.
Always change the filter when the ex-
haust filter indicator (Reset button 7)
lights up. It is designed to light up after
approx. 50 hours of operation which is
equivalent to about a year of average
use. It should be replaced sooner if it is
obviously soiled or no longer effective.
Make a note of the date on the filter.
The vacuum cleaner can still be used
with the exhaust filter indicator lit up.
However, the suction power will be re-
duced as will the effectiveness of the fil-
ter if it is not replaced in good time.
You can replace the exhaust filter sup-
plied with the vacuum cleaner with one
of the other types of filters if you wish
(see "Replacing one type of filter with
another").
Re-setting the filter change indicator
The filter change indicator needs to be
re-set each time the filter is replaced. To
do this the vacuum cleaner must be
connected to the electricity supply.
Press on the filter change indicator light
until it goes out. The display is now
back in the starting position again.
