This appliance contains the coolant isobutene(R600a),a
natural gas which is environmentally friendly. Although it is
flammable, it does not damage the ozone layer and does not
increase the greenhouse effect. The use of this coolant has,
however, led to a slight increase in the noise level of the
appliance. You might be able to hear the coolant flowing
around the system.
This is unavoidable, and does not have any adverse effect on
the performance of the appliance. Care must be taken during
the transportation and setting up the appliance that no parts
of the cooling system are damaged. Leaking coolant can
damage the eyes.
A wine cellar is the most practical space for storing wines. Its role is to balance the temperature and
humidity inside so that your wine does not lose its taste and its aromas.
Due to these heavy operations, noises can be heard. Most of the time, this is normal noise.
Before calling technical service for assistance, please read these few lines.
These sounds are completely normal: buzzing, roaring, clicking, cracking ...
When the cellar has just stopped working, you may hear a buzzing, roaring, clicking or squealing
noise. When the operation stabilizes, the sounds subside.
For direct cooling, some kind of irregular cracking, hissing, bubbling, crackling can often be heard
when the compressor is running for a while or has just stopped. This sound is caused by the relief of
stress due to expansion and contraction when temperature changes, and will not be affected by
normal application of the product.
The compressor consists of an electric motor and a compression device. Due to the heat produced
during the compression of the refrigerant, it is possible especially in summer when the ambient
temperature is higher that heat is emitted by the cellar. All of these phenomena are normal.
To reduce some noises:
First, make sure your cellar is on a level surface.
Location is important, do not lean the cellar against the wall.
The bottles must be correctly loaded to avoid parasitic vibrations.
The noise may come from the circulation fan, check that nothing is interfering with its operation.
