one of the following exhaust filters:

b AirClean Plus 50 (light blue)
c Silence AirClean 50 (grey)
d Active AirClean 50 (black)
e HEPA AirClean 50 (white)
Do not use more than one exhaust fil-
ter at a time.
When changing the filter, please note
1. If you wish to replace exhaust filter a
with filter b, c, d or e it is essential
that you remove the filter grille before
you fit the new exhaust filter.
If you are using exhaust filter c, d or
e, you must also activate the exhaust
filter TimeStrip change indicator (dia.

Maintenance indicator with reset but-
ton (dia. 45)
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 battery in the ra-
dio-control handle
Approximately every 18 months.
One 3 V battery (CR 2032) is required.
The vacuum cleaner can still be used
when the battery has run out or if
there is no battery fitted.
 To do so, switch the vacuum cleaner
on using the On/Off foot control .
The Standby indicator  on the va-
cuum cleaner will light up yellow.
 Press the restart button on the va-
cuum cleaner.
