Operating Noises - V-ZUG AG Mode D'emploi

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.
Description Cause
Droning Cooling aggregate
Humming Fan
Gurgling Cooling circuit
Babbling
Murmuring
Hissing Cooling circuit
Rattle Shelves, contents
Cracking Housing
Hissing valve

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.
Notes
Normal operating noise of the cooling aggregate.
The level is dependent on the size of appliance.
Normal operating noise of the fan.
Normal operating noise as coolant flows through
the circuit.
Normal operating noise as coolant is injected into
the condenser.
Arrange the shelves and contents so that they are fixed
and not touching one another.
Normal as materials expand and contract caused
by temperature variations (e.g. plastics, insulation).
Normal operating noise of the valve
