Contact your installer for more information.
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
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
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.

After-sales service and warranty

7.2.1

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 product are necessary within the warranty period,
contact your dealer and keep the warranty card at hand.
7.2.2 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 unit 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 unit.
▪ 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 electrical 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.
