Please contact your installer for more information.
WARNING: 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 shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
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 don’t 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.
