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.

NOTICE

maintenance design in terms of budgeting maintenance and inspection fees.
Depending on the content of the maintenance and inspection contract,
inspection and maintenance cycles may in reality be shorter than listed.
