If the air conditioner is not cooling or heating properly, the refrigerant may be
leaking, so consult your dealer.
Check with a qualified repairman before attempting any repairs, which might
accompany addition of refrigerant.
The refrigerant used in the air conditioner is safe. Although leaks should not occur,
if for some reason any refrigerant happens to leak into the room, make sure it does
not come in contact with any flame, such as fan heaters, kerosene heaters, or gas
ranges, as this may result noxious substances being generated.

CAUTION
Installation
WARNING
CAUTION
After a long use,
check the unit stand
and fittings for damage.
The unit may drop and cause
injury if damage is left
unrepaired.
Do not stand or sit on the outdoor
unit. Do not place any object on the
unit. Do not remove the fan guard.
The object or the person may
fall down or drop, causing injury.
Do not place a burning appliance
in places exposed to the airflow
from the unit or under the indoor
unit.
It may cause incomplete combus-
tion or deformation of the
unit from heat.
Do not expose young children,
plants or animals directly to
the airflow.
It may cause adverse effects on
the plant or the animal.
Do not block air inlets
or outlets.
Impaired airflow may result in
insufficient performance or
troubles.
Do not use the air conditioner
for preservation purposes.
Do not use it for preserving precision
instruments, foods, plants, animals,
works of fine arts etc.
Performance or quality may deteriorate
and animal or plant life may be shorter.
Do not touch the air inlets
or aluminum fins of the
outdoor unit.
You may get injured.
Before cleaning, be sure
to stop the operation and
turn the breaker OFF.
As a fan is rotating at a high speed,
cleaning during operation may cause
injury.
The air conditioner must be
earthed.
Incomplete earthing may result
in electric shocks or fire.
Do not connect the earth line to a gas pipe,
water pipe, lightening rod, or a telephone
earth line.
Do not connect the air conditioner
to a power supply different from
the specification.
It may cause trouble or fire.
Do not install the air conditioner

Do not place a vessel
containing water on the
unit.
Water may penetrate into the unit
and degrade electrical insulations,
resulting in an electric shock.
Do not leave sprays and
the like within 1m from
the air outlet.
Such containers may explode by
hot air coming from the indoor or
outdoor unit.
Do not wash the unit
with water.
It may cause an electric shock.
Do not place under the indoor
or outdoor unit anything which
must be kept away from moisture.
Indoor unit : Moisture in the air
may condense and drip in certain conditions.

Avoid overcooling or overheating.
Moderate room temperature setting
contributes to power saving.
Hang a blind or a curtain on the window.
This will enhance the cooling/heating effect
by intercepting direct sunlight and drafts.
A clogged air filter will reduce
the cooling/heating effect, leading to waste
of power. Clean the air filter monthly (every
two weeks as required) or so.
Please take note of the following points
Electric power is consumed even when the air
conditioner is not in operation.
When the unit is not used for a long period of
time such as during off-season, turn off the
breaker.
Operating conditions
If the operation is continued under any
conditions other than the following, the safety
device may work to stop the operation.
Also, dew may form on the indoor unit and drip
from it. (Cooling/DRY)
Operation limit differ according to the model.

Heating operation
Since the heating operation is performed by
taking the heat from outdoor into the room,
the heating capacity decreases as the outdoor
temperature lowers. If the room is not heated
sufficiently, it is recommended to use other
heating appliance at the same time.
Since the air conditioner heats the whole room
by circulating hot air, it takes some time to
heat the entire room completely.
If the outdoor unit gets frosted during heating
operation, the heating capacity is decreased.
In such case, the unit starts defrosting
operation.
No hot air comes out of the indoor unit during
defrosting operation.

Notes
In fixing the horizontal airflow direction, keep the horizontal airflow direction blades tilted
downward in the heating mode, and keep them nearly horizontal level in the cooling or DRY mode.
This will enhance the cooling and heating effect.
On the air-conditioners with vertical and horizontal swing function, be sure to adjust the airflow
directions using the remote controller. Do not force to adjust them by hand, or the unit may
malfunction.
