Airborne Noise Emission

The A-weighted sound pressure emitted by

this product is below 70 dB.

** The noise level can vary depending on the
site.

The figures quoted are emission level and are
not necessarily safe working levels.

Whilst there is a correlation between the
emission and exposure levels, this cannot be
used reliably to determine whether or not
further precautions are required.

Factor that influence the actual level of
exposure of the workforce include the
characteristics of the work room and the other
sources of noise, i.e. the number of
equipment and other adjacent processes and
the length of time for which an operator
exposed to the noise. Also, the permissible
exposure level can vary from country to
country.

This information, however, will enable the
user of the equipment to make a better
evaluation of the hazard and risk.

Limiting concentration

Limiting concentration is the limit of Freon gas
concentration where immediate measures can
be taken without hurting human body when
refrigerant leaks in the air. The limiting
concentration shall be described in the unit of

40°C when you clean the filters. It may
cause deformation or discoloration.

• Never use volatile substances when
you clean the filters. They may damage
the surface of the product.

Operation Tips!

• Do not overcool the room.
This is not good for the health and wastes elec­tricity.

•

Keep blinds or curtains closed.
Do not let direct sunshine enter the room
when the air conditioner is in operation.

• Keep the room temperature uniform.

Adjust the vertical and horizontal airflow di­rection to ensure a uniform temperature in
the room.

• Make sure that the doors and windows are

shut tight.
Avoid opening doors and windows as much
as possible to keep the cool air in the room.

• Clean the air filter regularly.

Blockages in the air filter reduce the airflow
and lower cooling and dehumidifying ef­fects. Clean at least once every two weeks.

Ventilate the room occasionally.

•

Since windows are kept closed, it is a good
idea to open them and ventilate the room
now and then.

When the air conditioner is not

going....

When air conditioner is not going to be used
for a long time.

1 Operate the air conditioner at the following

settings for 2 to 3 hours.

• Type of operation: Fan operation
mode.(Refer to page "Fan Mode")

• This will dry out the internal mechanisms.

2 Turn off the breaker.

CAUTION

time. Dirt may collect and may cause a
fire.

3 Remove the batteries from the Remote

Controller.

Helpful information

The air filters and your electiric bill.
If the air filters become clogged with dust, the

cooling capacity will drop, and 6% of the elec­tricity used to operate the air conditioner will
be wasted.

When the air conditioner is to be
used again.

1 Clean the air filter and install it in the indoor

unit. (Refer to page "Maintenance and Serv­ice")

2 Check that the air inlet and outlet of the in-

door/outdoor unit are not blocked.

Troubleshooting Tips! Save time and money!

Check the following points before requesting repairs or service.... If the malfunction persist,

please contact your dealer.

Case

The air conditioner does not
operate.

The room has a peculiar odor.

It seems that condensation is
leaking from the air condi­tioner.

Air conditioner does not oper­ate for about 3 minutes when
restart.

Does not cool or heat effec­tively.

The air conditioner operation
is noisy.

Crack sound is heard.

Filter sign lamp (LED) is ON.

Remote control display is
faint, or no display at all.

The error code is occurred
after lightning struck

Explanation

• Have you made a mistake in timer operation?

• Has the fuse blown or has the circuit breaker been tripped?

• Check that this is not a damp smell exuded by the walls,
carpet, furniture or cloth items in the room.

• Condensation occurs when the airflow from the air condi­tioner cools the warm room air.

• This is the protector of the mechanism.

• Wait about three minutes and operation will begin.

• Is the air filter dirty? See air filter cleaning instructions.

• The room may have been very hot when the room air condi­tioner was first turned on. Allow time for it to cool down.

• Has the setting temperature been set incorrectly?

• Are the indoor unit's air inlet or outlet vents obstructed?

• For a noise that sounds like water flowing.

- This is the sound of freon flowing inside the air conditioner

unit.

• For a noise that sounds like the compressed air releasing
into atmosphere.

- This is the sound of the dehumidifying water being

processed inside the air conditioning unit.

• This sound is generated by the expansion/contraction of the
inlet grille, etc. due to changes of temperature.

• Cleaning the filter, press the Timer button and ◀ button of
wired remote controller at the same time for 3 sec.

• Has the circuit breaker been tripped?

• Are the batteries inserted in the opposite (+) and (-) direc­tions?

• This product has been applied to the over current protection
circuit. Error can occur, but it is normal behavior. After few
minutes, It will operate normally.

Call the service immediately in the following situations

1 Anything abnormal such as burning smell, loud noise etc. happen. Stop the unit and turn the

breaker off. Never try to repair by yourself or restart the system in such cases.

2 Main power cord is too hot or damaged.
3 Error code is generated by self diagnosis.

4 Water leaks from indoor unit even if the humidity is low.

5 Any switch, breaker (safety, earth) or fuse fails to work properly

User must carry routine checkup & cleaning to avoid unit’s poor performance. In case of special
situation, the job must be carried out by service person only.
