Important Notice
․This Air Conditioner has been designed for common air conditioning for people. Do not apply to other purposes
such as for food, animals, plants, high precision machines or work of art.
․Do not install the unit in the following places. It may cause fire, deformation, corrosion or failure.
o Places where is filled with mineral oil mist or oil spray (including machinery oil) or vapor is produced.
o Places where is filled with sulfurous gas such as hot spring area.
․Do not install the unit in the following places, it may cause corrosion.
o Places where strong salty wind blows such as coast regions.
o An acid or alkaline environment.
․Pay attention to the following situations when the unit is installed in a hospital or other facilities where
o
electromagnetic wave is radiated from medical equipment.
o Do not install the unit where the electromagnetic wave is directly radiated to the electrical box, remote
control cable or remote-control switch
o o To avoid the influence of electromagnetic waves via air, wave generating machines such as radio, medical
equipment must be kept at least 3 meters form air conditioner.
o
․Do not install the unit in the place where wind directly blows on animals or plants. It could adversely affect them.
․Using wireless remote controller, the receiver may fail to receive signals due to effect of the lighting equipment.
Therefore, keep the receiver away from the lighting equipment more than 1 meter as possible
