12.2 Reduction in suction power
If the suction power decreases, carry out the
following steps:
1. Clean the filter cassettes by activating the
electromagnetic vibrator (set switch (2) to the
"IR" position).
2. Empty the container or replace the fleece filter
bag (5) or PE disposal bag (sold separately).
3. Replace the filter cassettes (14).
12.3 Renew the filter cassettes (14)
Shake the filter cassettes (14) once again before
replacing the filters, by switching on the
electromagnetic vibrator (set switch (2) to the "IR"
position).
Use a coin or a similar object to turn the locking
knob (12) on the locking bar (11) counter-clockwise
through 90° and push the bar (11) to the rear. Swing
up the hood and pull up the filter cassettes (14) to
remove them. Seal the removed filter cassettes
immediately in a dust-tight plastic bag and dispose
of them in accordance with regulations. Insert new
filter cassettes, ensuring they are correctly and
securely in place.

Regularly check the motor protection filter. If the
motor protection filter (13) is contaminated, this
indicates that the filter cassettes (14) may be
defective:
- Replace the filter cassettes (14).
- Replace the motor protection filter (13), or rinse it
under running water, dry it and then replace.
12.5 Water sensor
IMPORTANT - Clean the water
sensor regularly and check it for
signs of damage.
