5. OUTLET AIR SPEED AND COVERAGE RANGE
WThe air coverage range is the value up to the position where the air speed is 0.25m/sec.
When air is blown out horizontally from the unit at the Hi notch position.
The coverage range should be used only as a general guideline since it varies according to the size of the room and
the furniture inside the room.
The unit of pressure has been changed to Mpa based on the international SI system.
The corversion factor is : 1 (Mpa·G) = 10.2 (kgf/cm2·G)
