• 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.

• Consult your lacal dealer regarding what to do in case of refrigerant leakage. When the air conditioner is to be installed in a small room, it is necessary to take proper measures so that the amount of any leaked refrigerant does not exceed the concentration limit in the event of a leakage. Otherwise, this may lead to an accident due to oxygen depletion.
• Carry out the specified installation work after taking into account earthquakes. Failure to do so during installation work may result in the unit falling and causing accidents.
• Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by qualified personnel according to local laws and regulations and this installation manual. An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire.
• Be sure to switch off the unit before touching any electrical parts.
• Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal connections or wires.
• If refrigerant gas leaks during installation, ventilate the area immediately. Toxic gas may be produced if the refrigerant gas comes into contact with fire.
• Make sure to be materials in a compartment handling air for circulation through a duct supplying only one room.
Operation
• Unplug the unit if strange sounds, smell, or smoke comes from it. - Otherwise, it may cause electrical shock or a fire.
• Keep the flames away. - Otherwise, it may cause a fire.
• Take the power plug out if necessary, holding the head of the plug and do not touch it with wet hands. ­Otherwise, it may cause a fire or electrical shock.
• Do not open the suction inlet of the indoor/outdoor unit during operation. - Otherwise, it may electrical shock and failure.
• Do not allow water to run into electrical parts. - Otherwise, it may cause the failure of machine or electrical shock.
• Never touch the metal parts of the unit when removing the filter. - They are sharp and may cause injury.
• Do not step on the indoor/outdoor unit and do not put anything on it. - It may cause an injury through dropping of the unit or falling down.
• When the product is submerged into water, always contact the service center. - Otherwise, it may cause a fire or electrical shock.
• Take care so that children may not step on the outdoor unit. - Otherwise, children may be seriously injured due to falling down.
CAUTION
Installation
• Install the drain hose to ensure that drain can be securely done. - Otherwise, it may cause water leakage.
• Install the product so that the noise or hot wind from the outdoor unit may not cause any damage to the neighbors. - Otherwise, it may cause dispute with the neighbors.
• Always inspect gas leakage after the installation and repair of product. - Otherwise, it may cause the failure of product.
• Keep level parallel in installing the product. - Otherwise, it may cause vibration or water leakage.
Operation
• Avoid excessive cooling and perform ventilation sometimes. - Otherwise, it may do harm to your health.

INSTALLATION
ENGLISH
1 Install declination of the indoor unit is very important for the drain of the duct type air
conditioner.
2 Minimum thickness of the insulation for the connecting pipe shall be 5 mm(3/16 inch).
• Always lay the drain with downward inclination (1/100 to 1/50). Prevent any upward flow or reverse flow in any part.
• 10 mm or thicker formed thermal insulator shall always be provided for the drain pipe.
• Install the P-Trap (or U-Trap) to prevent a water leakage caused by the blocking of intake air filter.
• Upward routing not allowed
Lay the drain hose with a downward inclination so water will drain out.
• The unit must be declined to the drain hose connected when finished installation.
