Warning:

• Do not splash water over the unit and do not touch the unit with wet hands.

An electric shock may result.

• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance where it will be

exposed to the air discharged from the unit. Incomplete combustion may
result.

Warning:

• Do not remove the front panel or the fan guard from the outdoor unit when it

is running. You could be injured if you touch rotating, hot or high-voltage
parts.

• Never insert fingers, sticks etc. into the intakes or outlets, otherwise injury

may result, since the fan inside the unit rotates at high speed. Exercise par-
ticular care when children are present.

• If you detect odd smells, stop using the unit, turn off the power switch and

consult your dealer. Otherwise, a breakdown, electric shock or fire may
result.

• When you notice exceptionally abnormal noise or vibration, stop operation,

turn off the power switch, and contact your dealer.

• Do not over-cool. The most suitable inside temperature is one that is within

5 °C of the outside temperature.

• Do not leave handicapped people or infants sitting or standing in the path of

the airflow from the air-conditioner. This could cause health problems.

Caution:

• Do not direct the airflow at plants or caged pets.
• Ventilate the room frequently. If the unit is operated continuously in a closed

room for a long period of time, the air will become stale.

In case of failure

Warning:

• Never remodel the air conditioner. Consult your dealer for any repair or ser-

vice. Improper repair work can result in water leakage, electric shock, fire,
etc.

• If the remote controller displays an error indication, the air conditioner does

not run, or there is any abnormality, stop operation and contact your dealer.
Leaving the unit as it is under such conditions can result in fire or failure.

• If the power breaker is frequently activated, get in touch with your dealer.

Leaving it as it is can result in fire or failure.

• If the refrigeration gas blows out or leaks, stop the operation of the air con-

ditioner, thoroughly ventilate the room, and contact your dealer. Leaving the
unit as it is can result in accidents due to oxygen deficiency.

When the air conditioner is not to be used for a long
time

• If the air conditioner is not to be used for a long time due to a seasonal

change, etc., run it for 4 - 5 hours with the air blowing until the inside is com-
pletely dry. Failing to do so can result in the growth of unhygienic,
unhealthy mold in scattered areas throughout the room.

• When it is not to be used for an extended time, keep the [power supply]

turned OFF.
If the power supply is kept on, several watts or several tens of watts will be
wasted. Also, the accumulation of dust, etc., can result in fire.

• Keep the power switched ON for more than 12 hours before starting opera-

tion. Do not turn the power supply OFF during seasons of heavy use. Doing
so can result in failure.

• When not operating the unit for a long time during the winter season,

remove the water inside the water pipe to prevent freeze.

1.3. Disposing of the unit

Warning:

When you need to dispose of the unit, consult your dealer. If pipes are re-
moved incorrectly, refrigerant (fluorocarbon gas) may blow out and come into
contact with your skin, causing injury. Releasing refrigerant into the atmos-
phere also damages the environment.
