(Please install with the customer's consent in a location that follows the conditions listed below.)
(a) Where the following installation space is available, and where air does not gather.
(b) Where rain and sunlight do not directly hit the unit, and where there is enough air circulation.
(c) Also, where the unit cannot be buried by snow.
A location which can sustain the weight of the unit, and where noises and vibrations are not enhanced.
(d) Where blasts of cold or hot air and noise do not bother the neighbors.
(e) Where the unit does not receive heat radiation from other heat sources.
(f) Where there are no obstructions (animals, plants, etc.) to the suction inlet and blowing outlet.
(g) Where water may drain out.
(h) Please avoid the following locations.
1) Where there is constant exposure to harsh winds such as the top floors of a building. Also, locations with exposure to
salty air.
2) Where there are oil splashes, vapor, and smoke.
3) Where there are possibilities of flammable gas leaks.
(i) Installation space (on a flat surface)
If there are no open space to install the unit, and it must be installed in a location where there are obstructions such as a wall

1) Please install with the blowing
outlet facing the wall.
Over 600mm
(2) Moving / Installation of Unit
(a) Move the unit as close to the installation location as possible in its packed form.
(b) If it must be unpacked before moving, use a nylon sling, or apply a board to protect the unit from any damages and lift it with
a rope.
(c) Install the indoor unit so it will be horizontal, or so there will be a slight downward slope towards the drainage hole.
(d) Also, secure the legs of the unit to a firm foundation to prevent any instabilities.
(e) If there is a possibility of vibrations transferring to the house, apply a vibration prevention rubber (available in stores)
between the unit and the installation board and secure the unit.
(f) To ensure correct connections, mark each ends of the cables and the pipes with letters, A, B, and C. It is important to use the
same letter for the corresponding cables and pipes.
