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
