Do not wash the air conditioner with water,
as this may result in electric shocks or a fire.
Do not place water containers (flower vases,
etc.) on the indoor unit, as this may result in
electric shocks or a fire.
Do not install the air conditioner at any place
where there is a danger of flammable gas
leakage.
In the event of a gas leakage, build-up of gas
near the air conditioner may result in a fire.
Carry out drain piping properly to ensure
complete drainage.
If drain piping is not carried out properly, drain
will not flow out. Then, dirt and debris may be
accumulated in the drain piping and may cause
water leakage. If it occurs, stop the air condi-
tioner and call your local dealer for assistance.
The appliance is not intended for use by unat-
tended young children or persons who are
incompetent to operate air conditioners.
It may result in injury or electric shocks.
Children should be watched so that they do
not play with the indoor unit or its remote
controller.
Accidental operation by a child may result in
injury or electric shocks.
To avoid injury, do not touch the air inlet or
aluminum fins of the air conditioner.
Do not place objects in direct proximity of the
outdoor unit and do not let leaves and other
debris accumulate around the unit.
Leaves are a hotbed for small animals which can
enter the unit. Once in the unit, such animals can
cause malfunctions, smoke or a fire when mak-
ing contact with electrical parts.
Do not block air inlets nor outlets.
Impaired airflow may result in insufficient perfor-
mance or trouble.
Do not let children play on or around the out-
door unit.
If they touch the unit carelessly, injury may be
caused.
Turn off the power when the air conditioner is
not used for long periods of time.
Otherwise, the air conditioner may get hot or
catch on a fire due to dust accumulation.
Never touch the internal parts of the remote
controller.
Do not remove the front panel. Touching certain
internal parts will cause electric shocks and dam-
age to the remote controller. Please consult your
local dealer about checking and adjustment of
internal parts.
Do not leave the remote controller wherever
there is a risk of wetting.
If water gets into the remote controller there is a
risk of electrical leakage and damage to elec-
tronic components.
Watch your steps at the time of air filter
cleaning or inspection.
High-place work is required, to which utmost
attention must be paid.
If the scaffold is unstable, you may fall or topple
down, thus causing injury.
• NOTE TO SERVICE PERSONNEL
WARNING
RISK OF ELECTRIC SHOCKS OR, A FIRE
• When checking the electric components (such
as the inside of the control box, fan motor, drain
pump, etc.), make sure to shut off all power sup-
ply for the air conditioner (including both indoor
and outdoor units).
• When cleaning the heat exchanger, make sure
to remove the electronic components above (If
they get cleaning agent, there is a risk that the
components will burn out because of insulation
degradation.)
CAUTION! DANGER OF ELECTRIC SHOCKS
• Shut off power supply before work.
• Never open the control box lid for 10 minutes
after shutting off the power supply because
there is residual voltage.
• After opening the control box lid, measure resid-
ual voltage between the points shown Fig. 1 on
the Printed Circuit Board by the tester without
touching the live part and confirm that the resid-
ual voltage is DC50V or below.
• After power failure, operation will restart auto-
matically.
