Warning and Safety instructions
Technical safety

The refrigerant circuit has been checked for leaks. The wine
conditioning unit complies with all current local and national safety
requirements.

This wine conditioning unit contains the coolant Isobutane
(R600a), a natural gas which is environmentally friendly. Although it is
flammable, it does not damage the ozone layer and has a lower
greenhouse effect than some other refrigerants.
The use of this refrigerant has, however, led to a slight increase in
the noise level of the appliance. In addition to the noise of the
compressor, you might be able to hear the refrigerant flowing around
the system. Unfortunately, this cannot be avoided, but it does not
affect the performance of the wine conditioning unit.
When transporting and installing the wine conditioning unit, ensure
that no parts of the cooling circuit are damaged. Splashes of
refrigerant can damage the eyes.
In the event of any damage:
- Avoid naked flames or anything which creates a spark.
- Disconnect the wine conditioning unit from the mains electricity
supply.
- Ventilate the room in which the wine conditioning unit is located
for several minutes.
- Call Miele.
