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 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.
