1. Precautions
1-1 Installing the air conditioner
● 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 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 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.
24524(1)_1 56/10/3 7:06 PM Page 1-1
Do not spray any kind of liquid into the indoor unit. If this happens,
turn off the air conditioner and contact a service center.

Samsung Electronics1-2
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.
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.
24524(1)_1 56/10/3 7:06 PM Page 1-2
1-3 During operation(cont.)
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)
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.

Note : If the heat exchanger in the outdoor unit gets dusty, cooling efficiency may fall.
So clean the heat exchanger with water when it becomes dirty. However, be careful when you
wash the surface of the heat exchanger because it is very sharp.
