SPOTS ............................................12
To gain full advantage of the air conditioner’s
functions and to avoid malfunction due to
mishandling, we recommend that you read
this instruction manual carefully before use.
This air conditioner is classified under “appli-
ances not accessible to the general public”.
The precautions described herein are
classified as WARNING and CAUTION.
They both contain important information
regarding safety. Be sure to observe all
precautions without fail.
WARNING....... Failure to follow these
instructions properly
may result in personal
injury or loss of life.
CAUTION........ Failure to observe these
instructions properly
may result in property
damage or personal
injury, which may be
serious depending on
the circumstances.
1. SAFETY PRECAUTIONS
After reading, keep this manual in a con-
venient place so that you can refer to it
whenever necessary. If the equipment is
transferred to a new user, be sure also to
hand over the manual.
WARNING
Be aware that prolonged, direct expo-
sure to cool or warm air from the air
conditioner, or to air that is too cool or
too warm can be harmful to your phys-
ical condition and health.
When the air conditioner is malfunc-
tioning (giving off a burning odour,
etc.) turn off power to the unit and con-
tact your local dealer.
Continued operation under such circum-
stances may result in a failure, electric
shocks or fire hazards.
Consult your local dealer to install
your equipment.
Doing the work yourself may result in
water leakage, electric shocks or fire haz-
ards.
Consult your local dealer regarding
modification, repair and maintenance
of the air conditioner or the remote
controller.
Improper workmanship may result in water
leakage, electric shocks or fire hazards.
Do not place objects, including rods,
your fingers, etc., in the air inlet or out-
let.
Injury may result due to contact with the
air conditioner’s highspeed fan blades.
Beware of fire in case of refrigerant
leakage.
If the air conditioner is not operating cor-
rectly, i.e. not generating cool or warm air,
refrigerant leakage could be the cause.
Consult your dealer for assistance.
The refrigerant within the air conditioner
is safe and normally does not leak. How-
ever, in the event of a leakage, contact
with a naked burner, heater or cooker
may result in generation of noxious gas.
Do not longer use the air conditioner until
a qualified service person confirms that
the leakage has been repaired.
01_EN_3P107422-29P.fm Page 1 Thursday, January 17, 2008 1:46 PM

English 2
Consult your local dealer regarding
what to do in case of refrigerant leak-
age.
When the air conditioner is to be installed
in a small room, it is necessary to take
proper measures so that the amount of
any leaked refrigerant does not exceed
the concentration limit in the event of a
leakage. Otherwise, this may lead to an
accident due to oxygen depletion.
Contact professional personnel about
attachment of accessories and be
sure to use only accessories specified
by the manufacturer.
If a defect results from your own work-
manship, it may result in water leaks,
electric shock or fire.
Consult your local dealer regarding
relocation and reinstallation of the air
conditioner.
Improper installation work may result in
leakage, electric shocks or fire hazards.
Be sure to use fuses with the correct
ampere reading.
Do not use improper fuses, copper or
other wires as a substitute, as this may
result in electric shock, fire, injury or dam-
age to the unit.
Be sure to install an earth leakage
breaker.
Failure to install an earth leakage breaker
may result in electric shocks or fire.
Be sure to earth the unit.
Do not earth the unit to a utility pipe, light-
ning conductor or telephone earth lead.
Imperfect earthing may result in electric
shocks or fire.
A high surge current from lightning or
other sources may cause damage to the
air conditioner.
Consult the dealer if the air condi-
tioner submerges 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
shock, or fire may result.
Do not start or stop operating the air
conditioner with the power supply
breaker turned ON or OFF.
Otherwise, fire or water leakage may
result. Furthermore, the fan will rotate
abruptly if power failure compensation is
enabled, which may result in inlury.
Do not use the product in the atmo-
sphere contaminated with oil vapor,
such as cooking oil or machine oil
vapor.
Oil vapor may cause crack damage, elec-
tric shocks, or fire.
Do not use the product in places with
excessive oily smoke, such as cook-
ing rooms, or in places with flammable
gas, corrosive gas, or metal dust.
Using the product in such places may
cause fire or product failures.
Do not use flammable materials (e.g.,
hairspray or insecticide) near the
product.
Do not clean the product with organic
solvents such as paint thinner.
The use of organic solvents may cause
crack damage to the product, electric
shocks, or fire.
Be sure to use a dedicated power sup-
ply for the air conditioner.
The use of any other power supply may
cause heat generation, fire, or product
failures.
CAUTION
Do not use the air conditioner for pur-
poses other than those for which it is
intended.
Do not use the air conditioner for cooling
precision instruments, food, plants, ani-
mals or works of art as this may adversely
affect the performance, quality and/or
longevity of the object concerned.
Do not remove the outdoor unit’s fan
guard.
The guard protects against the unit’s high
speed fan, which may cause injury.

Do not place objects that are suscepti-
ble to moisture directly beneath the
indoor or outdoor units.
Under certain conditions, condensation
on the main unit or refrigerant pipes, air
filter dirt or drain blockage may cause
dripping, resulting in fouling or failure of
the object concerned.
To avoid oxygen depletion, ensure
that the room is adequately ventilated
if equipment such as a burner is used
together with the air conditioner.
After prolonged use, check the unit
stand and its mounts for damage.
If left in a damaged condition, the unit
may fall and cause injury.
Be sure that children, plants or ani-
mals are not exposed directly to air-
flow from the unit, as adverse effects
