SALES SERVICE AND WARRANTY
Warranty period
This product includes a warranty card that was filled out by the
dealer at the time of installation. The completed card was
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.
11.1. After-sales service
Recommendations for 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.
