● The air coverage range is the value up to the position
where the air speed is 1 ft/sec, when air is blown out
horizontally from the unit properly at the High speed
position.
The coverage range should be used only as a gen-
eral guideline since it varies according to the size of
the room and furniture arranged in the room.
