2. STANDARD OPERATION DATA

Total Electrical circuit Refrigerant circuit Indoor side Outdoor side

The unit of pressure has been changed to Mpa on the international system of unit(SI unit system).

The converted score against the traditional unit system can be gotten according to the formula below.

1(Mpa)=10.2(O/F·G)

3. ADDITIONAL REFRIGERANT CHARGE (R-22

…

kg(lbs))

4. OUTLET AIR SPEED AND COVERAGE RANGE

w The 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 furni-

ture inside the room.
