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
▪ Do NOT pierce or burn refrigerant cycle parts.

the defrosting process other than those recommended
by the manufacturer.
▪ Be aware that the refrigerant inside the system is
odourless.
