About the refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R32
Global warming potential value: 675
Periodical inspections for refrigerant leaks may be required
depending on the applicable legislation. Please contact your installer
for more information.
WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
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
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 from which you purchased
the unit.
Do not use the unit until a service person confirms that the
portion from which the refrigerant leaked is repaired.

After-sales service and warranty
12.3.1
Warranty period
▪ This product includes a warranty card that was filled in by the
dealer at the time of installation. The completed card has to be
checked by the customer and stored carefully.
▪ If repairs to the air conditioner are necessary within the warranty
period, contact your dealer and keep the warranty card at hand.
12.3.2
Recommended maintenance and
inspection
Since dust collects when using the unit for several years,
performance of the unit will deteriorate to some extent. As taking
apart and cleaning interiors of units requires technical expertise and
in order to ensure the best possible maintenance of your units, we
recommend to enter into a maintenance and inspection contract on
top of normal maintenance activities. Our network of dealers has
access to a permanent stock of essential components in order to
keep your air conditioner in operation as long as possible. Contact
your dealer for more information.
When asking your dealer for an intervention, always state:
▪ The complete model name of the air conditioner.
▪ The manufacturing number (stated on the nameplate of the unit).
▪ The installation date.
▪ The symptoms or malfunction, and details of the defect.
WARNING
▪ Do not modify, disassemble, remove, reinstall or repair
the unit yourself as incorrect dismantling or installation
may cause an electric shock or fire. Contact your
dealer.
▪ In case of accidental refrigerant leaks, make sure there
are no naked flames. The refrigerant itself is entirely
safe, non-toxic and mildly flammable, but it will
generate toxic gas when it accidentally leaks into a
room where combustible air from fan heaters, gas
cookers, etc. is present. Always have qualified service
personnel confirm that the point of leakage has been
repaired or corrected before resuming operation.
