This occurs after approx. 50 hours of
operation which is equivalent to about a
year of average use. The vacuum
cleaner can still be used. However, the
suction power will be reduced as will
the effectiveness of the filter if it is not
replaced in good time.
How to replace the exhaust filter
(dia. 32 + 33)
Do not use more than one exhaust fil-
ter at a time.
Open the dust compartment lid.
Lift the exhaust filter and remove it.
Insert a new exhaust filter making it
sure it goes in properly, then push it
down into position.
Press the exhaust filter change indic-
ator (dia. 10).
After approx. 10 - 15 seconds a thin red
line will appear in the left hand side of
the display (dia. 11).
If you wish to fit an AirClean filter,
see "Maintenance - Replacing one
type of exhaust filter with another".
Close the dust compartment lid.
Replacing one type of exhaust filter
with another (dia. 34)
Depending on model, your vacuum
cleaner will be fitted as standard with
one of the following exhaust filters:
a AirClean
b Active AirClean 50 (black)
c AirClean Plus 50 (light blue)
d HEPA AirClean 50 (white)
Do not use more than one exhaust fil-
ter at a time.
When using the AirClean filter please
note
An AirClean exhaust filter is supplied
with every packet of Miele dustbags. If
you wish to use this filter it is essential
that you use a filter grille (see "Optional
accessories").
Maintenance indicator with reset but-
ton (dia. 35)
Some models are fitted with a mainten-
ance indicator.
The indicator lights up after approx. 50
hours of operation, which is equivalent
to about a year of average use. The
level of soiling of the dust compartment
filter and the exhaust filter must be
checked at this point.
If the filters are replaced, the indicator
must be reset. To do this the vacuum
cleaner must be switched on.
Press the reset button.
The maintenance indicator will go out
and reset to zero.
The indicator can only be reset by
pressing the reset button after the
light has come on. Pressing the but-
ton at any other time will have no ef-
fect.
When to change the thread lifters
The thread lifters on the suction inlet to
the floorhead can be replaced. Check
them from time to time and replace
them if the pile has worn down.
