WARNING
▪ The refrigerant inside the unit is mildly flammable, but normally does NOT leak. If
the refrigerant leaks in the room and comes in contact with fire from a burner, a
heater, or a cooker, this may result in fire, or the formation of a harmful gas.
▪ Turn OFF any combustible heating devices, ventilate the room, and contact the
dealer 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.

Charging of refrigerant MUST be in accordance with the instructions from this
manual. See "19Charging refrigerant"[4108].
WARNING
▪ Only use R32 as refrigerant. Other substances may cause explosions and

▪ R32 contains fluorinated greenhouse gases. Its global warming potential (GWP)
value is 675. Do NOT vent these gases into the atmosphere.
