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.

BEFORE USE
7
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 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.

ENGLISH
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.
- This will dry out the internal mechanisms.
When the air conditioner is to be
used again.
1 Clean the air filter and install it in the indoor unit.
2 Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.
3 Check that the ground wire is connected
! CAUTION
correctly. It may be connect to the indoor
unit side.
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.
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.
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 reduces the airflow and lowers
the 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.
