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.
Be aware that the mentioned maintenance and replacement cycles do not relate to
the warranty period of the components.

inspection and maintenance cycles may in reality be shorter than listed.
