■Insert the power plug
properly.
Heat generated by a loose
power plug could cause electric
shock or fire.
Electrical outlet and power plug
shall be easily accessible.
■Do not modify the length of
the power cord or use an
extension cord.
It could cause electric shock or
fire.
■Do not be directly exposed

It could cause electric shock or
fire.
■Do not operate the unit with
wet hands.
It could cause an electric shock.
■ If there is a smell of burning,
stop the air conditioner and
disconnect the power supply.
The heat generated could cause
electric shock or fire. Please con-
sult an authorized dealer or serv-
ice centre.
■Do not damage or use an
unspecified power cord.
It will cause electrical shock or
fire.
■Do not insert finger, sticks
or other objects into the

ENGLISH
■ Switch off the power supply if
the unit is not going to be
used for a long period of time.
If dust accumulates on the plug, it
will generate heat and this could
cause a fire.
■Do not place combustor in
the path of the airflow from
the unit.
Incomplete combustion could
cause toxic gas (CO) poisoning.
■Inspect the unit for any
damage.
Ensure that the necessary repairs
are carried out.
■Do not remove the power
plug by pulling the cord.
Hold the plug when disconnect-
ing the plug from the wall outlet.
■Do not use for other pur-
poses.
Do not use for preservation pur-
poses. It will affect food quality,
animals or plants.
■Do not wash the unit with
water.
It could cause an electric shock.
■When cleaning the unit,
remove the plug.
This is to prevent injury due to
the rotating fan in the unit.
■ Ventilate the room
regularly.
If not ventilated regularly, the
lak of oxygen could cause
headaches.
■Do not sit or place
anything on the outdoor
unit.
You might fall off or the unit
might collapse.

are correct.
Pull out the power plug or turn off the
power breaker when:
■The air conditioner is not going to be used for
an extended period of time.
If the power supply cord connect, approximately
3.25 watts of electric power are used even if the main
unit is turned off by remote control.
■There is a danger of lightning.
The air conditioner is provided with a built-in protective
device, but the control equipment may be adversely
affected depending on the extent of lightning activity.
Regarding the batteries.
■The batteries can be used for approximately one year.
■Do not use rechargeable (Ni-Cd) batteries,
because such batteries differ from standard
dry-cell batteries in shape, dimensions and
performance.
■Be sure to replace the batteries with two new
batteries of the same type.
■Remove the batteries if the air conditioner is not going
to be used for an extended period of time.
■Do not dispose of empty batteries in household waste.
Take them to special local collection sites.

Operation Hints
■Adjust room temperature properly. Set the
temperature 1°C higher (Cooling Operation) or
2°C lower (Heating Operation) than actually
desired. Approximately 10% of electricity costs
can be saved.
■Prevent wastage with the Timer. Use Timer
when sleeping or going out to save electricity
cost.
■Clean the air filter regularly. Blockage in the air
filter reduces the airflow and lowers the cooling
or heating. Clean at least once every 2 weeks.
Otherwise, about 6% of electricity cost will be
wasted.
■Do not block the air outlet vents at outdoor unit.
Otherwise, it will lower the cooling or heating
performance.
1°C higher

ENGLISH
■Make sure that the doors and windows are shut.
Otherwise, cooling and heating performance will
be reduced and electricity cost is wasted.
■Proper airflow direction adjustment. Set the
airflow direction louvers horizontal for Cooling
Operation and downwards for Heating
Operation. Operation result will be better.
■Keep blinds or curtains closed. Do not let sun-
shine enter the room directly. About 5% of
electricity cost can be saved.
■Use insulating material for better performance.
Use insulating material during construction or
renovations. It will save electricity cost.

Better Care and Maintenance
Regular care and maintenance will extend the life of the air conditioner and prevent wastage of electricity. Before
performing any maintenance procedure, be sure to switch off the main power supply.
Once every 2 weeks is recommended.
■Clean the air filters.
■To remove the dust adhering to the filters,
either use a vacuum cleaner, or wash them in
water and dry in the shade.
■Re-insertthefilterscorrectlyattheleftandright,
with the side marked [FRONT] facing forward.
■Purchase replacement filters from your air con-
ditioner dealer if the air filters become damage.

Do not use water or volatile liquids.
■Do not make air conditioner wet, as there is the danger that it could cause
electric shocks.
Be sure not to apply water when cleaning or at any other time.
■Using water above 40°C could cause deformation and/or discolouration.
■Volatile liquids such as thinner or benzene may damage the air condi-
tioner.

• The filter is coated with catechin to prevent growth of bacteria and viruses.
• Reusable.
• Vacuum and fit it back in place
(Recommended : every 6 months)
■Recommended to change these filters every 3 years.
Do not reuse damaged filters.
Consult the nearest authorized dealer to purchase a new filter.
Catechin Air Purifying Filter No.: CZ-SF71P

If you operate the air conditioner with dirty filters:-
– Air is not purified
– Cooling capacity decreases
– Foul odour is emitted

Troubleshooting
Normal operation
QIs it okay? AThis is the answer.
During Soft Dry Mode
Operation, the air condi-
tioner stops.
Air conditioner has been
restarted, but does not
operate for 3 minutes.
During Automatic Airflow
Volume setting, indoor fan
stops occasionally.
Operation stops for about
12 minutes during heating.
(The operation lamp
blinks.)
It seems that fog is coming
out from the air
conditioner.
Airflow does not begin
immediately during Heat-
ing Operation.
The room has a peculiar
odour.
This is to protect the air conditioner. Wait until
the air conditioner begins operating.
SoftDryMode Operationis avery gentleCooling
Operation consisting primarily of dehumidifying.
The air conditioner may stop for approximately 6
minutes in order to prevent overcooling.
If the room temperature rises again, the opera-
tion will recommence.
If the airflow begins before its temperature be-
come warm, it will cause an undesired cooling
effect. In order to prevent this, the airflow will not
begin until it is sufficiently warm.
(The operation lamp will blink until the airflow
begins.)
This may be a damp smell exuded by the walls,
carpet, furniture or clothing in the room.
Condensation occurs when the airflow from the
air conditioner cools the room air.
This is to remove the smell exuded by the
surroundings.
This is the sound of refrigerant flowing inside the
air conditioner unit.
This is the sound of reversing the freon flow in-
side the unit at the starting and finishing the de-
frosting during Heating operation.
This is to melt the frost which has accumulated on the out-
door unit (Defrosting Operation). This will take no longer than
about 12 minutes, so wait for operation. (Frost accumulates
on the outdoor unit when the outdoor temperature is low and
the humidity is high.) Water comes out from the outdoor unit.
Stop for 12 minutes.
Sight
Blinks
A sound like water flowing
can be heard. A noise that
sounds like the com-
pressed air releasing into
atmosphere.
