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 non-combustible, but it will
generate toxic gas when it accidentally leaks into a room where combustion 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.
Be aware that the mentioned maintenance and replacement cycles do not relate to
the warranty period of the components.
