ELECTRICAL WARNINGS
If an abnormal situation arises (like a burning smell), immediately turn o 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.
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.
Do not allow children to play with the air conditioner. Children must be
supervised around the unit at all times.

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.
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.
Disconnection must be incorporated in the fixed wiring in accordance with the
wiring rules.
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 insucient
power supply can cause fire or electrical shock.
Keep power plug clean. Remove any dust or grime that accumulates on or
around the plug. Dirty plugs can cause fire or electric shock.
If connecting power to fixed wiring, an all-pole disconnection device which has
at least 3mm clearances in all poles, and have a leakage current that may exceed
10mA, the residual current device(RCD) having a rated residual operating current
not exceeding 30mA, and disconnection must be incorporated in the fixed wiring
in accordance with the wiring rules.
