TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:

• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air con­ditioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block
the air flow or weaken the cooling / dehumidifying functions.

ENGLISH

Preparing for operation

- Contact an installation specialist for installation.

- Use a dedicated circuit.

Usage

- Being exposed to direct airflow for an extended period of time could be hazardous to your
health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

- Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves
or other heating devices.

- Do not use this air conditioner for non-specified special purposes (e.g. preserving precision de­vices, food, pets, plants, and art objects). Such usage could damage the items.

Cleaning and maintenance

- Do not touch the metal parts of the unit when removing the filter. Injuries can occur when han­dling sharp metal edges.

- Do not use water to clean inside the air conditioner. Exposure to water can destroy the insula­tion, leading to possible electric shock.

- When cleaning the unit, first make sure that the power and breaker are turned off. The fan ro­tates at a very high speed during operation. There is a possibility of injury if the unit’s power is
accidentally triggered on while cleaning inner parts of the unit.

MAINTENANCE AND SERVICE

ENGLISH

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 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 re-

duce 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.

- Operate the air conditioner at the following

settings for 2 to 3 hours.

Type of operation: Fan operation
mode.(refer fan mode)

This will dry out the internal mechanisms.

- Turn off the breaker.

- Remove the batteries from the remote con-

troller.

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.

- Clean the air filter and install it in the indoor

unit. (refer air filters)

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

door/outdoor unit are not blocked.

- Check that the ground wire is connected cor-

rectly. It may be connect to the indoor unit
side.

CAUTION

Turn off the breaker when the air condi­tioner is not going to be used for a long
time.
Dirt may collect and may cause a fire.

MAINTENANCE AND SERVICE

21

ENGLISH

Call the service immediately in the following situations

- 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.

- Main power cord is too hot or damaged.

- Error code is generated by self diagnosis.

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

- 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.

The air conditioner
does not operate.

- Have you made a

mistake in timer op­eration?

- Has the fuse blown

or has the circuit
breaker been
tripped?

The room has a pecu­liar odor.

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

It seems that conden­sation is leaking from
the air conditioner.

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

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

- This is the protector
of the mechanism.

- Wait about three
minutes and opera­tion will begin.

Does not cool or heat
effectively.

- 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 temperature
been set incorrectly?

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

The air conditioner op­eration is noisy.

- 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.

Crack sound is heard.

- This sound is gener­ated by the expan­sion / constriction of
the front panel, etc.
due to changes of
temperature.

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

- Are the batteries de­pleted?

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

Filter sign lamp (LED)
is ON.

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