2 About the system
WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
2.1 Indoor unit
CAUTION
Do NOT insert fingers, rods or other objects into the air
inlet or outlet. When the fan is rotating at high speed, it will
cause injury.
INFORMATION
The sound pressure level is less than 70 dBA.
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.
