After-sales service and warranty

7.3.1

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 product are necessary within the warranty period,
contact your dealer and keep the warranty card at hand.
7.3.2 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 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 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 and non-toxic. R410A is a non-combustible
refrigerant, and R32 is a mildly flammable refrigerant,
but they will generate a toxic gas when they
accidentally leak 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.
