SAFETY INSTRUCTIONS
Do not install the air conditioner on an unstable surface or where there may be a danger of
unit falling. It may result in death, serious injury or product failure.
Be cautious when you unpack or install the air conditioner. Failure to do so may result in
serious injury or product failure.
Operation
Be sure to use only those parts which are listed in the service parts list. Never attempt to modify
the equipment. It may result in death, serious injury, effect on product performance or product failure.
Only use components that are approved by the manufacturer and do not repair or modify them.
Failure to do so may result in electric shock, effect on product performance or product failure.
SAFETY INSTRUCTIONS

Only use the refrigerant specified on the air conditioner label. Failure to do so may result in
explosion or fire.
enter
Do not let the air conditioner run for a long time when the humidity is very high or when a door or
window has been left open or in small place without ventilation. Failure to do so may result in product
failure, explosion or fire.
ON OFF
When there is a gas leak, ventilate sufficiently before using the air conditioner again. Failure to do
so may result in explosion or fire.
There is risk of damage or loss of property.
Do not block the inlet or outlet of air flow. It may effect product performance.
or serious injury.
or health complications.
For inner cleaning, contact an Authorized Service Center or a dealer.
Do not use harsh detergent that causes corrosion or damage on the unit. Harsh detergent may also
cause failure of product, fire, or electric shock.
Use non-inflammable gas (nitrogen) to check for leak and to purge air. Using compressed air or
flammable gas may cause fire or explosion.
Stop operating and close the window in a storm or hurricane.If possible remove the product from the
window before a hurricane arrives.
Unplug the power plug when the air conditioner is not used for an extended period of time. Failure to
do so may result in product failure.

BEFORE USE
Prior to Operation
Preparing for Operation
1. Contact an installation specialist for
installation.
2. Plug in the power plug properly.
3. Use a dedicated circuit breaker.
4. Do not use an extension cord.
5. Do not start/stop operation by plugging/
unplugging the power cord.
6. If the cord/plug is damaged, replace it with
only an authorized replacement part.
Usage
1. Being exposed to direct airflow for a long
time may be hazardous to your health. Do
not expose occupants, pets, or plants to
direct airflow for a long time.
2. Due to the possibility of oxygen deficiency,
ventilate the room when using the
appliance together with stoves or other
heating devices.
3. Do not use this air conditioner for nonspecified special purpose (e.g. preserving
precision devices, food, pets, plants, or art
objects). Such use may damage your
properties.
Cleaning and Maintenance
1. Do not touch the metal parts of the unit
when removing the filter. Injury can occur.
2. Do not use water to clean inside the air
conditioner. Exposure to water can destroy
the insulation, lead to electric shock or
effect product performance.
3. When cleaning the unit, first make sure that
the power and breaker are turned off. The
fan rotates at a very high speed during
operation. There is a possibility of injury if
the unit’s power is triggered while cleaning
inner parts of the unit.
Service
For repair and maintenance, contact your
authorized service dealer.
