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.
WARNING
Stop operation and shut OFF the
power if anything unusual occurs
(burning smells etc.).
Leaving the unit running under such
circumstances may cause breakage,
electrical shock or fire. Contact your
dealer.
