immediately for instructions.
Refrigerant gas may product toxic gas if it •
comes in contact with fi re such a from a fan,
heater, stove or cooking device. Exposure to
this gas could cause severe injury or death.
For refrigerant leakage, consult your dealer.•
Refrigerant gas is heavier than air and replaces
oxygen. A massive leak could lead to oxygen
depletion, especially in basements, and an as-
phyxiation hazard could occur leading to serious
injury or death.
Safely dispose of the packing materials.•
Packing materials, such as nails and other metal
or wooden parts, may cause stabs or other inju-
ries.
Tear apart and throw away plastic packaging
bags so that children will not play with them.
Children playing with plastic bags face the dan-
ger of death by suffocation.
If equipment utilizing a burner is used in the •
same room as the air conditioner, there is
the danger of oxygen defi ciency which could
lead to an asphyxiation hazard resulting in
serious injury or death.
Be sure to ventilate the room suffi ciently to avoid
this hazard.

[EXPLANATION OF HEATING OPERATION]
DEFROST OPERATION
As the frost on the coil of an outdoor unit in-•
crease, heating effect decreases and the system
goes into DEFROST OPERATION.
The indoor unit fan stops and the remote control-•
ler display shows “
”.
After 6 to 8 minutes (maximum 10 minutes) of •
DEFROST OPERATION, the system returns to
HEATING OPERATION.
Regarding outside air temperature and
heating capacity
The heating capacity of the air conditioner de-•
clines as the outside air temperature falls. In this
case, use the air conditioner in combination with
other heating systems.
A warm air circulating system is employed, and •
therefore it takes some time until the entire room
is warmed up after the start of operation.
An indoor fan runs to discharge a gentle wind •
automatically until the temperature inside the air
conditioner reaches a certain level. At this time,
the remote controller displays “
”. Leave it
as it stands and wait for a while.
When the warm air stays under the ceiling and •
your feet are cold, we recommend that you use a
circulator (a fan to circulate the air inside the
room). For details, consult your dealer.

indoor unit.
They may deform due to the heat.
Never place objects near the air inlet and the air •
outlet of the unit. It may cause deterioration in
the effect or stop in the operation.
Turn off the main power supply switch when it is •
not used for long periods of time. When the main
power switch is turned on, some watts of elec-
tricity is being used even if the system is not
operating. Turn off the main power supply switch
for saving energy. When reoperating, turn on the
main power supply switch 6 hours before opera-
tion for smooth running (Refer to “MAINTE-
NANCE”).
