Installation

• Always perform grounding. - Otherwise, it may cause electrical shock. 

• For installation of the product, always contact the service center or a professional installation

agency. - Otherwise, it may cause a fire, electrical shock, explosion or injury.

• Securely attach the electrical part cover to the indoor unit and the service panel to the outdoor unit.

- If the electrical part cover of the indoor unit and the service panel of the outdoor unit are not
attached securely, it could result in a fire or electric shock due to dust, water, etc.

• Always install an air leakage breaker and a dedicated switching board. - No installation may cause a

fire and electrical shock.

• Do not keep or use flammable gases or combustibles near the air conditioner. - Otherwise, it may

cause a fire or the failure of product.

• Ensure that an installation frame of the outdoor unit is not damaged due to use for a long time. 

- It may cause injury or an accident.

• Do not disassemble or repair the product randomly. - It will cause a fire or electrical shock.

• Do not install the product at a place that there is concern of falling down. - Otherwise, it may result

in personal injury.

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

• Use a vacuum pump or Inert (nitrogen) gas when doing leakage test or air purge. Do not compress

air or Oxygen and Do not use Flammable gases. Otherwise, it may cause fire or explosion. There is
the risk of death, injury, fire or explosion.

• Consult your lacal dealer regarding what to do in case of refrigerant leakage.

When the air conditioner is to be installed in a small room, it is necessary to take proper measures
so that the amount of any leaked refrigerant does not exceed the concentration limit in the event of
a leakage. Otherwise, this may lead to an accident due to oxygen depletion.

• Carry out the specified installation work after taking into account earthquakes.

Failure to do so during installation work may result in the unit falling and causing accidents.
