Important information regarding the refrig-
erant used
This product contains fluorinated greenhouse gases.
Refrigerant type: R410A
GWP
(1)
value: 2087.5
(1)
GWP = global warming potential
NOTICE
In Europe, the
greenhouse gas emissions
of the
total refrigerant charge in the system (expressed as
tonnes CO
2
-equivalent) is used to determine the
maintenance intervals. Follow the applicable legisla-
tion.
Formula to calculate the greenhouse gas emis-
sions:
GWP value of the refrigerant × Total refriger-
ant charge [in kg] / 1000

WARNING
When the air conditioner is malfunctioning (giving off a
burning odor, etc.), turn off the power to the air condi-
tioner and contact your local dealer.
Continued operation under such circumstances may result
in a failure, electric shocks or a fire.
Consult your local dealer regarding modification,
repair and maintenance of the air conditioner.
Improper workmanship may result in water leakage, electric
shocks or a fire.
Be sure to use fuses with the correct ampere reading.
Do not use improper fuses, copper or other wiring as a sub-
stitute, as this may result in electric shocks, a fire, injury or
damage to the air conditioner.
Consult your local dealer if the air conditioner sub-
merges owing to a natural disaster, such as a flood or
typhoon.
Do not operate the air conditioner in that case, or otherwise
a malfunction, electric shocks, or a fire may result.
Start or stop the air conditioner with the remote con-
troller. Never use the power circuit breaker for this pur-
pose.
Otherwise, it may cause a fire or water leakage. Further-
more, if an automatic restart control is provided against
power failure and the power is recovered, the fan will rotate
suddenly and may cause injury.
Do not use the air conditioner in the atmosphere con-
taminated with oil vapor, such as cooking oil or
machine oil vapor.
Oil vapor may cause crack damage to the air conditioner,
electric shocks, or a fire.
Do not use flammable materials (e.g., hairspray or
insecticide) near the air conditioner.
Do not clean the air conditioner with organic solvents
such as paint thinner.
