2.2 Instructions for safe operation
WARNING: MILDLY 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.
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.
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.
CAUTION
ALWAYS use a user interface to adjust
the position of the flaps and louvers.
When the flaps and louvers are
swinging and you move them forcibly
by hand, the mechanism will break.
CAUTION
NEVER expose little children, plants or
animals directly to the airflow.

2 User safety instructions
WARNING
Do NOT place objects below the indoor
and/or outdoor unit that may get wet.
Otherwise condensation on the unit or
refrigerant pipes, air filter dirt or drain
blockage may cause dripping, and
objects under the unit may get dirty or
damaged.
WARNING
Do NOT place a flammable spray
bottle near the air conditioner and do
NOT use sprays near the unit. Doing
so may result in a fire.
CAUTION
Do NOT operate the system when
using a room fumigation-type
insecticide. Chemicals could collect in
the unit, and endanger the health of
people who are hypersensitive to
chemicals.
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.
CAUTION
Do NOT touch the heat exchanger fins.
These fins are sharp and could result
in cutting injuries.
WARNING
Be careful with ladders when working
in high places.
WARNING
Improper detergents or cleaning
procedure may cause damage on
plastic components or water leakage.
Splashed detergent on electric
components, such as motors, may
cause failure, smoke or ignition.
DANGER: RISK OF
ELECTROCUTION
Before cleaning, be sure to stop the
operation, turn the breaker off or pull
out the supply cord. Otherwise, an
electric shock and injury may result.
WARNING
Stop operation and shut off the
power if anything unusual occurs
(burning smells etc.).
