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.
WARNING
Charging of refrigerant MUST be in accordance with the instructions from this
manual. See
"7.6 Charging refrigerant" [
4
49].
WARNING
▪
Only use R32 as refrigerant. Other substances may cause explosions and
accidents.
▪
R32 contains fluorinated greenhouse gases. Its global warming potential (GWP)
value is 675. Do NOT vent these gases into the atmosphere.
▪
When charging refrigerant, ALWAYS use protective gloves and safety glasses.
