1. Precautions
1-1 Installing the air conditioner
•Uses should not install the air conditioner by themselves. Ask the dealer or authorized company to
install the air conditioner except window-type air conditioner in U.S.A and Canada.
•If you don't install the air conditioner properly, it may cause a fire, a water leakage or an electric
shock.
•You must install the air conditioner according to the national wiring regulations and safety regulations.
•Install the indoor unit higher than 2.5m from the floor to avoid the injury caused by the operation of
the fan.(except the window-type air conditioner)
•The manufacturer is not responsible for any accidents or injury caused by an incorrect installation.
•When installing the built-in type air conditioner, keep all electric cables such as the power cable and
the connection cord in
•pipes, ducts, or cable channels to protect them from the danger of impact or any other incidents.
1-2 Power supply and circuit breaker
•If the power cord of the air conditioner is damaged, it must be replaced by the manufacturer or a
qualified person in order to avoid a hazard.
•The air conditioner must be plugged into an independent circuit if applicable or connect the power
cable to the auxiliary circuit breaker. An all pole disconnection form the power supply must be
incorporated in the fixed wiring with a contact opening of>3mm.
•Do not extend an electric cord to the air conditioner.
•The air conditioner must be plugged in after you complete the installation.
1-3 During operation
•Do not repair the air conditioner at your discretion. It is recommended to contact a service center
directly.
•Never spill any kind of liquid on the air conditioner. If this happens, turn off the air conditioner and
contact an authorized service center.
•Do not insert anything between the airflow blades to prevent damage of the inner fan and consequent
injury. Keep children away from the air conditioner.
•Do not place any obstacles in front of the air conditioner.
•Do not spray any kind of liquid into the indoor unit. If this happens, turn off the air conditioner and
contact a service center.
•Make sure that the air conditioner is well ventilated at all times. Do not place a cloth or other materials
over it.
•Remove the batteries if you don't use the remote control for a long time. (If applicable)
•Use the remote control within 7 meters from the indoor unit. (If applicable)

1-4 Disposing of the unit
•Before the throwing out the air conditioner, remove the batteries from the remote control.
•When you dispose of the air conditioner, consult your dealer. If pipes are removed incorrectly,
refrigerant may blow out and cause air pollution. When it contacts with your skin, it can cause skin
injury.
•The package of the air conditioner should be recycled or disposed of properly for environmental
reasons.
1-5 Others
•Never store or load the air conditioner upside down or sideways to prevent the damage to the
compressor.
•Young children or infirm persons should be always supervised when they use the air conditioner.
•Max current is measured according to IEC standard for safety.
•Current is measured according to ISO standard for energy efficiency.

2-1 The Feature of Product
•Fast cooling
If you want the strong and cool air, just select Fast function! It will get you the strongest air!
•Wind-Free Cooling
Use the Wind-Free Cooling function to enjoy a mild breeze coming through fine holes in the Wind-Free
panel instead of air coming directly through the air flow blades.
•Motion detection
Use the motion detection function to make the air conditioner detect people and blow air directly or
indirectly. With no detection, energysaving mode is operated..
•Eco
Use the Single User function when you’re along at home. Aside from energy savings from the inverter
technology, the Single User Mode will further minimize your energy consumption and reduce your
electricity bill by adjusting the maximum operating capacity of the compressor.
•Easy Filter
There is no grille to remove before separating the filter from the air conditioner! Therefore, filter can
be cleaned easily and more frequently. Constant filter cleaning will prevent dust from entering the
product or accumulating on the filter.
•good'sleep function
good’sleep function will allow you to have deep, good night’sleep by adjusting the temperature, fan
speed and air flow direction.
•Smart Install
When the installation is done, your product will examine itself through trial operation to check if it
was installed properly.
•Easy Installation
It’s so easy to install! You can easily hang the product on the wall and connect the pipes and wires by
opening the cover on the bottom of the product. Now you won’t have to tilt the product to connect the
pipe and the wires!
