7.3 About the refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
Refrigerant type: R410A
Global warming potential (GWP) value: 2087.5
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg]/1000
Contact your installer for more information.
WARNING: MILDLY FLAMMABLE MATERIAL
The R32 refrigerant (if applicable) in this unit is mildly
flammable. Refer to the outdoor unit specifications for the
type of refrigerant to be used.
WARNING
The appliance using R32 refrigerant shall be stored so as
to prevent mechanical damage and in a well-ventilated
room without continuously operating ignition sources (e.g.
open flames, an operating gas appliance, or an operating
electric heater). The room size shall be as specified in the
General safety precaution.
WARNING
▪ Do NOT pierce or burn refrigerant cycle parts.
▪ Do NOT use cleaning materials or means to accelerate
the defrosting process other than those recommended
by the manufacturer.
▪ Be aware that the refrigerant inside the system is
odourless.
WARNING
▪ R410A is a non-combustible refrigerant, and R32 is a
mildly flammable refrigerant; they normally do NOT
leak. If the refrigerant leaks in the room and comes into
contact with fire from a burner, a heater, or a cooker,
this may result in a fire (in case of R32), or the
formation of a harmful gas.
▪ Turn OFF any combustible heating devices, ventilate
the room, and contact the dealer from where you
purchased the unit.
▪ Do NOT use the unit until a service person confirms
that the part from which the refrigerant leaked has been
repaired.
