Precautions

Safety

WARNING

• Do not disassemble or modify unit.
It may cause failure and electric shock.

• Do not damage or use an alternate power cord.
It may cause fire and electric shock.
If the power cord is damaged, it must be replaced by the manufacturer or an
authorized service center or a similarly qualified person in order to avoid a hazard.

• Do not direct airflow straight into persons to avoid possible health hazard.

• Do not open the unit during operation.
It may cause electric shock.

• Do not use the power cord near flammable gas or combustibles, such as gasoline,
benzene, thinner, etc.
It may cause an explosion or fire.

• Do not let children hang on the air conditioner or bracket.
A serious injury may occur.

• Avoid fire hazard or electric shock. Do not use an extension cord or an adaptor
plug. Do not remove any prongs from the power cord.

• Be sure the air conditioner is properly grounded. To minimize shock and fire
hazards, proper grounding is important. The power cord is equipped with a
three-prong grounding plug for protection against shock hazards.

• Your air conditioner must be used in a properly grounded wall receptacle. If the
wall receptacle you intend to use is not adequately grounded or protected by a
time delay fuse or circuit breaker, have a qualified electrician install the proper
receptacle. Ensure the receptacle is accessible after the unit installation.

• Be sure the electrical service is adequate for the model you have chosen. This
information can be found on the serial plate, which is located on the side of the
cabinet and behind the grille.

death if ingested.

CAUTION

• When the air filter is to be removed, do not touch the metal parts of the unit.
It may cause injury.

• When the unit needs cleaning, switch off, and turn off the circuit breaker.
Do not clean unit when power is on as it may cause fire, electric shock or injury.

• Do not place obstacles around air inlets or inside of air outlet.
It may cause failure or accident.

• Clean with a soft cloth only. Do not use strong detergents that contain wax or
thinners as it may damage the product.

• Use caution when unpacking and installing. Sharp edges could cause injury.

 Page 4 

CAUTION

• Do not clean the air conditioner with water.
Water may enter the unit and degrade the insulation which could lead to

electric shock.

• Do not put a pet or house plant where it will be exposed to direct air flow.
This could injure the pet or harm the plant.

• Hold the plug by the head of the power plug when taking it out.
Otherwise, it may cause electric shock and damage.

• Ensure that the installation is properly secured to prevent the product from
potentially falling.

• Do not place heavy objects on the power cord and ensure that the cord is not
compressed.

Otherwise, there is danger of fire or electric shock.

• If water is spilled on the unit, turn off the unit and switch off the circuit breaker.
Isolate supply by taking the power-plug out and contact a qualified service
technician.

• Do not use near gas stove or other gas burning appliances, as air flow may affect
gas combustion.

• Do not use for any purpose other than room comfort.
Do not use this air conditioner to preserve precision devices, food, pets, plants,

and art objects. It may cause deterioration.

• Turn off the main power switch if the unit is not to be used for an extended time.

NOTICE

• The relative humidity of the room should be less than 80%. If the unit is used in a condition
with a relative humidity over 80%, there will be condensed water on the surface of the unit.

• Performance may be reduced outside of these operating temperatures.

NOTICE

Always wait 3 minutes when turning the unit off and then on again, or when changing from

7. Make sure the air flow inside and outside is not obstructed by anything.

Air Directional Louvers

The louvers will allow you to direct the air
flow up or down (on some models) and left
or right throughout the room as needed. Use
the SWING button until the desired up/down
direction is obtained.
