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 Powersupply 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. Precautions

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

uFast cooling

If you want the strong and cool air, just select Fast function! It will get you the strongest air!

uWind-Free Cooling

Use the Wind-Free Cooling function to enjoy a mild breeze coming through ne holes

in the Wind-Free panel instead of air coming directly through the air ow blades.

uMotion 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.

uEco

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.

uEasy Filter

There is no grille to remove before separating the lter from the air conditioner! Therefore, lter

can be cleaned easily and more frequently. Constant lter cleaning will prevent dust from enter-

ing the product or accumulating on the lter.

ugood’sleep function

good’sleep function will allow you to have deep, good night’sleep by adjusting the temperature,

fan speed and air ow direction.

uSmart Install

When the installation is done, your product will examine itself through trial operation to check if

it was installed properly.

uEasy 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!
