● The air coverage is the figure up to the

position where the air speed is 1 ft./s.,

when air is blown out horizontally from

the unit properly at the High speed posi-

tion.

The coverage should be used only as a

general guideline since it varies accord-

ing to the size of the room and furniture

arranged inside the room.
