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 in-
jury may result, since the fan inside the unit rotates at high speed. Exer-
cise particular 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 opera-
tion, 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 serv-
ice. 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
conditioner, thoroughly ventilate the room, and contact your dealer. Leav-
ing 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
completely 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 op-
eration. 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
atmosphere also damages the environment.

3. 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 min-
utes) 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 al-
ready 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 re-
quested, the symbol that corresponds to the requested mode will blink, notify-
ing the user that the mode is currently 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/heating function.
• The outdoor units stop when all the indoor units connected to the counterpart
outdoor units stop.
• During heating operation, even if the indoor unit is set to operation while the
outdoor unit is in defrosting operation, operation starts after the defrosting op-
eration of the outdoor unit has ended.
