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 and 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 indoor air quickly, in a short period of time.
• 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.

IMPORTANT SAFETY INSTRUCTIONS
ENGLISH
CAUTION
Installation
• Always check for gas (refrigerant) leakage after installation or repair of product. Low refrigerant lev-
els may cause failure of product.
• Install the drain hose to ensure that water is drained away properly. A bad connection may cause
water leakage.
• Keep level even when installing the product. To avoid vibration or water leakage.
• Do not install the product where the noise or hot air from the outdoor unit could damage the neigh-
borhoods. It may cause a problem for your neighbors.

• Do not expose the skin directly to cool air for long periods of time. (Don't sit in the draft.) This could
harm to your health.
• Do not use the product for special purposes such as preserving foods, works of art, etc. It is a con-
sumer air conditioner, not a precision refrigeration system. There is risk of damage or loss of prop-
erty.

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 period 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 de-
vices, 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 han-
dling sharp metal edges.
• Do not use water to clean inside the air conditioner. Exposure to water can destroy the insula-
tion, leading to possible electric shock.
• When cleaning the unit, first make sure that the power and breaker are turned off. The fan ro-
tates 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
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 horizon-
tal airflow direction to ensure a
uniform temperature in the
room.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and win-
dows as much as possible to
keep the cool air in the room.
Clean the air filter regularly.
Blockages in the air filter re-
duces the airflow and lowers
the cooling and dehumidifying
effects. Clean at least once
every two weeks.
Ventilate the room occasion-
ally.
Since windows are kept
closed, it is a good idea to
open them and ventilate the
room now and then.
When air conditioner is not going
to be used for a long time.
1Operate 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.
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 elec-
tricity used to operate the air conditioner will
be wasted.
When the air conditioner is to be
used again.
1Clean the air filter and install it in the in-
door unit.
2Check that the air inlet and outlet of the in-
door/outdoor unit are not blocked.
3Check that the ground wire is connected
correctly. It may be connect to the indoor
unit side.
CAUTION
Turn off the breaker when the air condi-
tioner is not going to be used for a long
time.
Dirt may collect and may cause a fire.
