manufacturer or a qualified person in order to avoid a hazard.
The air conditioner must be plugged into an independent circuit if applicable or

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)
No children Nearby
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.
Current is measured according to ISO standard for energy efficiency.
