b) Persons and Product
• The mains outlet must be located near to the product and be easily accessible.
• Only use the power adapter that comes with the product to power the audio
extractor.
• Never connect or disconnect power adapters if your hands are wet.
• The product is built according to protection class II. Only connect the power
adapter to a normal mains socket connected to the public supply. Before plugging
in the power adapter, check whether the voltage stated on the power adapter
complies with the voltage of your electricity supplier.
• Never unplug the mains plug by pulling on the cable. Grip the sides of the plug and
then pull it out of the socket.
• Do not touch the power adapter if there are any signs of damage, as this may
result in a fatal electric shock!
Switch off the mains voltage to the mains socket to which the power adapter is
connected (switch off at the corresponding circuit breaker or remove the safety
fuse, then switch off at the RCD protective switch so that all poles of the mains
socket are disconnected).
You can then unplug the power adapter from the mains socket. Dispose of the
faulty power adapter in an environmentally friendly manner and discontinue use.
Replace it with a power adapter of the same design.
• Always lay cables so that nobody can trip over or become entangled in them. This
poses a risk of injury.
• Ensure that the cable is not bent or compressed when you are setting up the
product.
• Never use the product immediately after it has been brought from a cold room into
a warm one. The condensation generated could destroy the product. The power
adapter may also cause a fatal electric shock!
Allow the product to reach room temperature before connecting it to the power
supply and putting it to use. This may take several hours.
• Never pour any liquids over electrical devices or put objects filled with liquid right
next to the device. If liquid or an object does enter the interior of the device, power
down the respective socket (e.g. switch off the circuit breaker) and then unplug
the mains plug from the mains socket. Discontinue use and take the product to a
specialist repair centre.
