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. Precautions

5

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.

it will adjust the fan speed and ai ow direction automatically to help you stay comfortable and
refreshed.

u

Fast cooling

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

u

Comfort cooling

If you want the comfortable and refreshing air, Comfort function will spread the cool air indirectly
to you, so that you can stay comfortable.

u

Single User

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.

u

Easy 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enter­ingtheproductoraccumulatingonthelter.

u

good’sleep function

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

fanspeedandairowdirection.

u

Smart Install

When the installation is done, your product will examine itself through trial operation to check if
it was installed properly.

u

Easy Installation

It’s so easy to install! You can easily hang the product on the wall and connect the pipes

u

How to Approach Test Mode

You can approach the test mode by pressing the on/off
switch of indoor unit for 5 seconds.

u

Test mode operation option

After installing the air conditioner, check whether each subordinate is normally operated or not by
operating the test mode.

• When an Error occurs, display the Error Mode.

• Operation Mode : Cool mode. operate the cool mode by operating the compressor by force

without the compressor ON/OFF according to the set temperature/indoor temperature. (Do not
follow the antifreeze control)

• Up-down louver : Up-down swing mode

• Indoor Fan : Turbo

Note

• Because the heat mode operate the cool mode by force not related to the set temperature

/ indoor temperature, check whether each subordinate is operated normally or not after
completing installation and must turn off the power of the air conditioner.
