Noises and alarms

10.1 

Operating noise

The appliance can make various noises during operation. Although the appliance is
noise-optimized, some noise cannot be eliminated completely. This noise depends on
the size of the appliance, how it is installed and the cooling requirements (e.g. fast cool-
ing), the ambient temperature and the installation conditions. Operating noises are partic-
ularly audible immediately after switching on the compressor; however, these noises be-
come quieter as the appliance runs.
Unusual noises are often caused by improper installation. The appliance must be in-
stalled on a level and stable surface. In open kitchens or in the case of appliances in-
stalled in partitioned areas, normal operating noises may seem louder. This is not a fault
but rather an effect of the design/architecture.
