Technical safety

The coolant system is tested for leaks. This appliance complies
with statutory safety requirements and the appropriate EU
guidelines.

This appliance contains the coolant Isobutane (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. In addition to the noise of the
compressor, 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 of the
appliance that no parts of the cooling system are damaged. Leaking
coolant can damage the eyes.
In the event of any damage:
– avoid naked flames or anything which creates a spark,
– disconnect the appliance from the mains electricity supply,
– ventilate the room where the appliance is located for several
minutes, and
– contact the Miele Service Department.
