Refrigerant R32: GWP 675
THE REFRIGERANT
§To realize the function of the air conditioner unit, a special refrigerant
circulates in the system. The used refrigerant is the fluoride R32, which is
specially cleaned. The refrigerant is flammable and inodorous. Furthermore,
it can leads to explosion under certain conditions. But the flammability of the
refrigerant is very low. It can be ignited only by fire.
§Compared to common refrigerants, R32 is a nonpolluting refrigerant with no
harm to the ozonosphere. The influence upon the greenhouse effect is also
lower. R32 has got very good thermodynamic features which lead to high
energy efficiency. The units therefore need a less filling.

This product contains fluorinated greenhouse gases
Refrigerant leakage contributes to climate change. Refrigerant
with lower global warming potential (GWP) would contribute less
to global warming than a refrigerant with higher GWP if leaked to
the atmosphere. This appliance contains a refrigerant fluid with a
GWP equal to [675]. This means that if 1 kg of this refrigerant fluid
would be leaked to the atmosphere the impact on global warming
would be [675] times higher than 1 kg of CO2 over a period of 100
years. Never try to interfere with the refrigerant circuit yourself or
disassemble the product yourself. These tasks should be carried

57 GB
only by licensed authorized technician.
Ensure no following objects are under the indoor unit:
§Microwaves, ovens and other hot objects.
§Computers and other high electrostatic appliances.
§Sockets that plug frequently.
The joints between indoor and outdoor unit shall not be reused,
unless after re-flaring the pipe.
The specifications of the fuse are printed on the circuit board, such
as: 3.15A/250V AC, etc.
If your air conditioner is not fitted with a supply cord and a plug, an
anti-explosion all-pole switch must be installed in the fixed wiring
and the distance between contacts should be no less than 2.5 mm.
If your air conditioner is permanently connected to the fixed wiring,
an anti-explosion residual current device (RCD) having rated
