Safety Precautions
Read Safety Precautions Before Installation
Incorrect installation due to ignoring instructions can cause serious damage or injury.
The seriousness of potential damage or injuries is classified as either a WARNING or CAUTION.
This symbol indicates that ignoring instructions may cause death or serious injury.
This symbol indicates that ignoring instructions may cause moderate injury to
your or damage to your appliance or other property.
This appliance can be used by children aged from 8 years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience and knowledge if they have been given supervision
or instruction concerning use of the appliance in a safe way and understand the hazards involved.
Children shall not play with the appliance. Cleaning and user maintenance shall not be made by
children without supervision.
I. Installation Warnings
Ask an authorized dealer to install this air conditioner. Inappropriate installation may cause
water leakage, electric shock, or fire.
All repairs, maintenance and relocation of the unit must be performed by an authorized service
technician. Inappropriate repairs can lead to serious injury or product failure.
II. Warnings for product use
If an abnormal situation arises (like a burning smell), immediately turn off the unit and pull
the power plug.
Call your dealer for instructions to avoid electric shock, fire or injury.
Do not insert fingers, rods or other objects into the air inlet or outlet. This may cause injury,
since the fan may be rotating at high speeds.
Do not use flammable sprays such as hair spray, lacquer or paint near the unit. This may cause
fire or combustion.
Do not operate the air conditioner in places near or around combustible gases. Emitted gas
may collect around the unit and cause explosion.
Do not operate the air conditioner in a wet room (e.g., bath room or laundry room). This can
cause electrical shock and cause the product to deteriorate.
Do not expose your body directly to cool air for a prolonged period of time.
III. Electrical Warnings
Only use the specified power cord. If the power cord is damaged, it must be replaced by the
manufacturer or certified service agent.

Keep power plug clean. Remove any dust or grime that accumulates on or around the plug.
Dirty plugs can cause fire or electric shock.
Do not pull power cord to unplug unit. Hold the plug firmly and pull it from the outlet. Pulling
directly on the cord can damage it, which can lead to fire or electric shock.
Do not use an extension cord, manually extend the power cord, or connect other appliances
to the same outlet as the air conditioner. Poor electrical connections, poor insulation, and
insufficient voltage can cause fire.
IV. Cleaning and Maintenance Warnings
Turn off the device and pull the plug before cleaning. Failure to do so can cause electrical
shock.
Do not clean the air conditioner with excessive amounts of water.
Do not clean the air conditioner with combustible cleaning agents. Combustible cleaning
agents can cause fire or deformation.
⚫If the air conditioner is used together with burners or other heating devices, thoroughly ventilate
the room to avoid oxygen deficiency.
⚫Turn off the air conditioner and unplug the unit if you are not going to use if for a long time.
⚫Turn off and unplug the unit during storms.
⚫Make sure that water condensation can drain unhindered from the unit.
⚫Do not operate the air conditioner with wet hands. This may cause electric shock.
⚫Do not use device for any other purpose than its intended use.
⚫Do not climb onto or place objects on top of the outdoor unit.
⚫Do not allow the air conditioner to operate for long periods of time with doors or windows open,
or if the humidity is very high.
