• 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
service. Improper repair work can result in water leakage, electric shock,
fire, etc.
2. How to operate

Before starting operation
• Start running after the "PLEASE WAIT" display has disappeared. The "PLEASE
WAIT" display briefly appears on the room temperature display (max. 3 minutes)
when the power is turned on and after a power failure. This does not indicate any
failure of the air-conditioner.
• The choice of indoor unit operation mode is limited by the operation status of the
outdoor unit to which a given indoor unit is connected. If an outdoor unit and some
of the indoor units that are connected to the outdoor units are already operating in
the cooling mode, for example, only the cooling mode is available for the rest of
the units in the same group. If a different mode is requested, the symbol that cor-
responds to the requested mode will blink, notifying the user that the mode is cur-
rently unavailable. The same is true for the dry and heating mode. This restriction,
however, does not apply to the models that support a simultaneous cooling/heat-
ing function.
• The outdoor units stop when all the indoor units connected to the counterpart out-
door units stop.
• During heating operation, even if the indoor unit is set to operation while the out-
door unit is in defrosting operation, operation starts after the defrosting operation
of the outdoor unit has ended.

• 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.
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.
Caution:
Even if the [ON/OFF] Button is pressed immediately after the operation is once
stopped, operation is not restarted for about 3 minutes. This function protects
the machine. It automatically starts operation after the lapse of approximately
3 minutes.

Caution:
Never expose your body directly to cool air for a long time. Excessive expo-
sure to cool air is bad for your health, and should therefore be avoided.
Dry operation
The dry is a microcomputer-controlled dehumidifying operation which controls
excessive air-cooling according to the room temperature of your choice. (Not usable
for heating.)
