1. SAFETY PRECAUTIONS
To gain full advantage of the air conditioner's functions and to
avoid malfunction due to mishandling, please read this oper-
ation manual carefully before use.
This air conditioner comes under the term "appliances not
accessible to the general public".
• This manual classifies the precautions into WARN-
INGS and CAUTIONS.
Be sure to follow all the precautions below: They are
all important for ensuring safety.
WARNING........ Indicates a potentially hazardous situa-
tion which, if not avoided, could result in
death or serious injury.
CAUTION......... Indicates a potentially hazardous situa-
tion which, if not avoided, may result in
minor or moderate injury.
It may also be used to alert against
unsafe practices.
• After reading, keep this manual in a convenient 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 exposure to cool or
warm air from the air conditioner, or to air that is too
cool or too warm can be harmful to your physical con-
dition and health.
When the air conditioner is malfunctioning (giving
off a burning odor, etc.), turn off the power to the air
conditioner and contact your local dealer.
Continued operation under such circumstances may
result in a failure, electric shocks or a fire.
Consult your local dealer about installation work.
Doing the work yourself may result in water leakage,
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.
English
Do not place objects, including rods, your fingers,
etc., in the air inlet or outlet.
Injury may result due to contact with the air conditioner's
highspeed fan blades.
Beware of a fire in case of refrigerant leakage.
If the air conditioner is not operating correctly, i.e. not
generating cool or warm air, refrigerant leakage could be
the cause. Consult your local dealer for assistance. The
refrigerant used for the air conditioner is safe and nor-
mally does not leak. However, if the refrigerant leaks
and gets in contact with a naked burner, heater or cooker,
it may generate hazardous compounds. Turn off the air
conditioner and call your local dealer. Turn on the air con-
ditioner after the qualified service person makes sure to
confirm that the leakage is repaired.
Consult your local dealer regarding what to do in
case of refrigerant leakage.
When the air conditioner is 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 workmanship, it may
result in water leakage, electric shocks or a fire.
Consult your local dealer regarding relocation and
reinstallation of the air conditioner.
Improper installation work may result in leakage, electric
shocks or a fire.
Be sure to use fuses with the correct ampere read-
ing.
Do not use improper fuses, copper or other wiring as a
substitute, as this may result in electric shocks, a fire
injury or damage to the air conditioner.
Be sure to earth the air conditioner.
Do not earth the unit to a utility piping, lightning conduc-
tor or telephone earth lead.
Imperfect earthing may result in electric shocks or a fire.
A high surge current from lightning or other sources may
cause damage to the air conditioner.
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in
electric shocks or a fire.
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 other-
wise 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
purpose.
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
contaminated 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.
