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.

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.

If dirt is conspicuous, wash with a neutral
detergent in lukewarm water.
If hot water (40°C or more) is used, it may
be deformed.
- After washing with water, dry well in the
shade.
Do not expose the air filter to direct sunlight
or heat from a fire when drying it.
- Install the air filter.
MAINTENANCE AND SERVICE 19
When it 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.
This will dry out the internal mechanisms.
- Turn off the breaker.
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.
- Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
- Check that the ground wire is connected

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

20 MAINTENANCE AND SERVICE
ENGLISH
Troubleshooting Tips! Save time and money!
Check the following points before requesting repairs or service.... If the malfunction persist,
please contact your dealer.
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.
