Operating Noises
Noises which are entirely normal
The chill cabinet is cooled by a compressor
(refrigeration aggregate). The compressor
pumps coolant through the cooling
system, producing operating noises. Even
when the compressor cuts out, noises cau-
sed by changes in temperature and pressu-
re are unavoidable.
This appliance is fitted with a quiet com-
pressor and a low-noise cooling circuit
designed in line with the latest technical
developments.
However, a certain level of noise, depen-
dent on the size of the appliance, is inevi-
table. Operating noise will be most audible
immediately after the compressor cuts in. It
becomes quieter as the operating period
continues.
Noises which are not normal
Unusual noise is normally the result of
improper installation. The appliance must
be installed or built-in so that it is level and
stable. Under no circumstances must
tubing come into contact with a wall,
other furniture or with another tubing.
Where the appliances are installed in
open-plan kitchens or in partition walls,
the level of operating noise will be heard
more acutely. However, this is due to the
surrounding architecture and not to a fault
with the appliance.
Description Cause Notes
Droning Cooling aggregate Normal operating noise of the cooling aggregate.
The level is dependent on the size of appliance.
Humming Fan Normal operating noise of the fan.
Gurgling Cooling circuit Normal operating noise as coolant flows through
Babbling the circuit.
Murmuring
Hissing Cooling circuit Normal operating noise as coolant is injected into
the condenser.
Rattle Shelves, contents Arrange the shelves and contents so that they are fixed
and not touching one another.
Cracking Housing Normal as materials expand and contract caused
by temperature variations (e.g. plastics, insulation).
