1. Precautions

Users should not install the air conditioner by themselves. Ask the dealer or authorized company to install the air conditioner except the window-type air conditioner in U.S.A and Canada. If you dont 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 from 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 dont 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 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.

Classification

Class Q A
Description Whenever the air conditioner is turned on, it stinks. There are no components in the air conditioner sending out chemical smells. But, when the air conditioner is turned on, other smell sources are sucked into the air conditioner and get out of it. So, find and root out the smell sources. Generally, when the drain hose is taken out to the washing room or there are sources of smells such as a diaper bin, a shoe shelf or a socks bin, bad smells generate. Also, it occurs where glass cleaners or air fresheners are used; when they are sucked in interacting with dusts and moistures inside, bad smells generate. These kinds of organic materials noxious to human bodies. So, we recommend against the use of them. Whenever the air conditioner is turned on, it smells sour. When the room is papered recently, its paste smells would be sucked inside. Also, when the air conditioner is installed in the study room of young boys loving sweat-generating activities such as the basketball, excessive sweats evaporate and get sucked into the air conditioner resulting in bad smells. So, find and root out the problem or refresh the room frequently. Whenever the air conditioner is turned on, it smells musty. It is due to the improper keeping of the product after its use. When keeping the product, dry up the inside with the operation of Ventilation to prevent must. When the product is kept without drying up the inside with Ventilation, mold would grow inside resulting in must. So, open the windows and switch on the Ventilation function to get rid of the saturated smell inside. Whenever the air conditioner is turned on, it sends out bad smells such as stale smells. It occurs generally when there are pet animals in the house. Their smells stay at the same place. But, when the air conditioner is turned on, the air gets circulated resulting in the circulation of the smells. So, find and root out the problem or refresh the room frequently. It sends out bad smells. When the air filter is filthy, it could send out bad smells. So, clean the filter and ventilate the room with the windows open while operating the Ventilation function. It won't start. There is a power failure or it is plugged out. Also, check if the power distribution panel is switched off. It goes off during operation. When the hot air does not escape properly, it goes off during operation. It occurs when it does not ventilate properly because the outdoor unit is covered, the back of the outdoor unit is blocked by a cardboard or a plywood panel, and the front of the outdoor unit is blocked by the closed window or other obstacles. Clear the above obstacles from the outdoor unit. It generally works properly. But, when it's considerably hot, it goes off during operation. It occurs when the outdoor unit is exposed to direct sunlight and the hot air does not escape properly. Set up a sun blind over the outdoor unit and clear the neighboring obstacles from the outdoor unit to provide good ventilation. When it goes off frequently during a heat wave, it would prevent the turn-off and increase the cooling capacity cleaning the outdoor unit or spraying some water to the heat exchanger. The remote controller won't operate. When the batteries run out or the transmitter or receiver of the remote controller is blocked by obstacles, change the batteries or keep the obstacles away from the controlling area. Also, the remote controller may not work under intensive light from a 3-wave length lamp or a neon sign due to the EMI. In this case, take the remote controller closer to the receiver.
