NOTICE!
The escape of refrigerant contributes to climatic
change. In the event of escape, refrigerant with
a low greenhouse potential has a lesser impact
on global warming than those with a high
greenhouse potential. This device contains
refrigerant with a greenhouse potential of 2088.
That means the escape of 1 kg of this refrig-
erant has an effect on global warming that is
2088 times greater than 1 kg CO
2
, based on
100 years. Do not conduct any work on the
refrigerant circuit or dismantle the device -
always enlist the help of qualified experts.
