This symbol indicates the possibility
of personnel injury or loss of life.
CAUTION
This symbol indicates the possibility of
property damage or serious consequences.
WARNING
This appliance is not intended for use by persons(including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play with the appliance.
WARNINGS FOR PRODUCT USE
• If an abnormal situation arises (like a burning smell), immediately turn off the unit and disconnect the
power. 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 your air conditioner in a wet room such as a bathroom or laundry room. Too much
exposure to water can cause electrical components to short circuit.
• Do not expose your body directly to cool air for a prolonged period of time.
• Do not allow children to play with the air conditioner. Children must be supervised around the unit at
all times.
• If the air conditioner is used together with burners or other heating devices, thoroughly ventilate the
room to avoid oxygen deficiency.
• In certain functional environments, such as kitchens, server rooms, etc., the use of specially
designed air-conditioning units is highly recommended.
CLEANING AND MAINTENANCE WARNINGS
• Turn off the device and disconnect the power 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.

CAUTION
• Turn off the air conditioner and disconnect the power if you are not going to use it 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.
ELECTRICAL WARNINGS
• Only use the specified power cord. If the power cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
• 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 modify the length of the power supply cord or use an extension cord to power the unit.
• Do not share the electrical outlet with other appliances. Improper or insufficient power supply can
cause fire or electrical shock.
• The product must be properly grounded at the time of installation, or electrical shock may occur.
• For all electrical work, follow all local and national wiring standards, regulations, and the Installation
Manual. Connect cables tightly, and clamp them securely to prevent external forces from damaging
the terminal. Improper electrical connections can overheat and cause fire, and may also cause
shock. All electrical connections must be made according to the Electrical Connection Diagram
located on the panels of the indoor and outdoor units.
• All wiring must be properly arranged to ensure that the control board cover can close properly. If the
control board cover is not closed properly, it can lead to corrosion and cause the connection points
on the terminal to heat up, catch fire, or cause electrical shock.
• All wiring and disconnection must be incorporated in the fixed wiring in accordance with the wiring
rules.
