9 LIGHT BULB REPLACEMENT*
9.1 Special safety instructions
WARNING: HOT SURFACES!
The UV-C lamps get very hot during operation.
– Touching the light source immediately after switching off the appliance can cause
severe skin burns!
– Allow the lamps to cool down for at least 15 minutes after switching them off
before you replace them.
– If in doubt, wear heat-resistant safety gloves.
WARNING!
The fan continues to run for a while after the appliance has been switched off.
– To avoid injury, do not reach into the appliance until the fan has stopped!
CAUTION!
The glass bodies of the UV-C light bulbs are sensitive and can be damaged by touch,
thus reducing their effectiveness.
– Never touch the glass of the light bulb.
– If in doubt, wear gloves!
– Only touch the light bulbs by their end parts.
CAUTION!
Do not dispose of used UV-C light bulbs in the household waste.
– Contact your local waste disposal authority for instructions on proper disposal.
– Further information on disposal can be found in chapter 14 on page 39 of these
operating
instructions.
NOTE
Due to the production process, new light bulbs can develop an unusual smell due to
the high-energy radiation. This odour usually disappears within the first 20 – 50
hours of operation.
* Applies to models with integrated UV lamps

5. Open the lid of the housing using the handle until it clicks
vertically into place.
WARNING OF HAND INJURY!
Make sure that the lid of the housing is opened as far as it
will go and secured with the locking lever so that it cannot
fall down while the filter is being changed.
CAUTION!
Danger of tipping with the lid open!
Do not steady yourself by holding onto the appliance, and
do not move it – otherwise the device could tip over!
6. Grasp the HEPA filter on the side of the frame and pull it up and
out of the housing. To protect against injury, avoid direct contact
with the filtration surface.
For filter disposal, please observe the special safety instructions on
page 28.
7. Align the new HEPA filter so that its rubber seal faces down towards
the grille that separates the filter compartment from the fan
compartment.
8. Insert the new HEPA filter into the housing so that its rubber seal
faces downwards. Lightly press the filter element down so that it is
firmly seated in the housing.
9. Slowly close the lid with one hand while at the same time using
the other hand to push the locking lever forwards to release
the locking mechanism. Then grab the transport handle with
both hands and carefully lower the lid until it is completely
closed.
10. As soon as the lid is closed, fasten it with the locking lever by
turning it 90° anti-clockwise and then pressing it into the housing.
Removing the key ensures that the lid remains locked and cannot
be opened by unauthorized persons.
