Operating noises
Noises which are totally normal
The refrigerator is cooled by a compressor (cooling aggregate). The compressor pumps coolant through the cooling system, and
this produces noise. Even when the compressor cuts out, noises caused by temperature and pressure variations are unavoidable.
This cooler is fitted with a quiet compressor and low-noise cooling circuit in accordance with the latest state of technology.
However, certain noises are unavoidable and their intensity depends on the size of the cooler.
Operating noises are most audible immediately after the compressor cuts in. They become quieter as the operating period
continues.
Noises which are not normal
Most unusual noises are caused by improper installation. The cooler must be installed or built-in so that it is level and stable. Under
no circumstances should pipes be in contact with a wall, other furniture or one another.
Where coolers are built in to open-plan kitchens or partition walls, normal operating noises will be more audible. However, this
is due to the surrounding architecture and not to any fault with the cooler.

Cause
Comment
Droning
Cooling aggregate
Normal operating noise of the cooling aggregate. The level is dependent
on the size of cooler
Humming
Fan
Normal operating noise of the fan
Gurgling
Cooling circuit
Normal operating noise as coolant flows through the circuit
Babbling
Murmuring
Hissing
Cooling circuit
Normal operating noise as coolant is injected into the condenser
Cracking
Cooler housing
Normal as materials expand and contract due to temperature
variations (e.g. plastics, insulation)
