WARNING
The refrigerant inside the unit is mildly
flammable, but normally does NOT
leak. If the refrigerant leaks in the room
and comes in contact with fire from a
burner, a heater, or a cooker, this may
result in fire, or the formation of a
harmful gas.
Turn off any combustible heating
devices, ventilate the room, and
contact the dealer where you
purchased the unit.
Do NOT use the unit until a service
person confirms that the part from
which the refrigerant leaked has been
repaired.
WARNING
▪ Do NOT pierce or burn refrigerant
cycle parts.
▪ Do NOT use cleaning materials or
means to accelerate the defrosting
process other than those
recommended by the manufacturer.
▪ Be aware that the refrigerant inside
the system is odourless.
WARNING
The appliance shall be stored in a
room without continuously operating
ignition sources (example: open
flames, an operating gas appliance or
an operating electric heater).
DANGER: RISK OF
ELECTROCUTION
To clean the air conditioner or air filter,
be sure to stop operation and turn all
power supplies off. Otherwise, an
electric shock and injury may result.
CAUTION
After a long use, check the unit stand
and fitting for damage. If damaged, the
unit may fall and result in injury.
WARNING
Be careful with ladders when working
in high places.
DANGER: RISK OF
ELECTROCUTION
Before cleaning, be sure to stop the
operation, turn the breaker off or pull
out the supply cord. Otherwise, an

(burning smells etc.).
Leaving the unit running under such
circumstances may cause breakage,
electric shock or fire. Contact your
dealer.

About the system
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
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, animals, or
works of art.
3.1
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.
