recommended by the manufacturer.
▪ Be aware that the refrigerant inside
the system is odourless.

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.
