therefore marked with
.
Please observe the following items in any case:
G
The units are suitable for indoor use only. Protect
them against dripping water and splash water, high
air humidity, and heat (admissible ambient tempera-
ture range 0 – 40 °C).
G
Do not place any vessel filled with liquid on the units,
e. g. a drinking glass.
G
The heat generated within the mixer must be dissi-
pated by air circulation; therefore, never cover the air
vents.
G
Do not operate the mixer and immediately discon-
nect the power supply unit from the socket
1. if the mixer or the power supply unit is visibly dam-

No guarantee claims for the units and no liability for
any resulting personal damage or material damage
will be accepted if the units are used for other pur-
poses than originally intended, if they are not cor-
rectly connected or operated, or if they are not
repaired in an expert way.
If the units are to be put out of operation
definitively, take them to a local recycling
plant for a disposal which is not harmful to the
environment.
WARNING
The power supply unit uses dangerous
mains voltage (230 V~). Leave servic-
ing to skilled personnel only; inexpert
handling may result in electric shock.
