Installation under high-humidity atmosphere
In some cases including the rainy season, especially inside of the ceiling may become high-humidity atmosphere
(dew-point temperature: 73.4 °F (23 °C) or higher).
1. Installation to inside of the ceiling with tiles on the roof
2. Installation to inside of the ceiling with slated roof
3. Installation to a place where inside of the ceiling is used for pathway to intake the fresh air
4. Installation to a kitchen
In the above cases, additionally attach the heat insulator to all positions of the air conditioner, which come to
contact with the high-humidity atmosphere. In this case, arrange the side plate (Check port) so that it is easily
removed.
Apply also a sufficient heat insulation to the duct and connecting part of the duct.
