WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
CAUTION
The indoor unit contains radio equipment, minimum separation distance between
the radiating part of the equipment and the user is 10 cm.
NOTICE
Do NOT use the system for other purposes. In order to avoid any quality
deterioration, do NOT use the unit for cooling precision instruments, food, plants,

3 | About the system
INFORMATION
The sound pressure level is less than 70dBA.
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 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.
