13 Maintenance and service
NOTICE
Never inspect or service the unit by yourself. Ask a
qualified service person to perform this work.
WARNING
Never replace a fuse with a fuse of a wrong ampere ratings
or other wires when a fuse blows out. Use of wire or
copper wire may cause the unit to break down or cause a
fire.
CAUTION
Do not insert fingers, rods or other objects into the air inlet
or outlet. Do not remove the fan guard. When the fan is
rotating at high speed, it will cause injury.
CAUTION
After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and result in injury.
NOTICE
Do not wipe the controller operation panel with benzine,
thinner, chemical dust cloth, etc. The panel may get
discoloured or the coating peeled off. If it is heavily dirty,
soak a cloth in water-diluted neutral detergent, squeeze it
well and wipe the panel clean. Wipe it with another dry
cloth.

After-sales service and warranty

13.1.1

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.
13.1.2 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 non-combustible, 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.
