Setting the total stop switch
Check that energizing has taken place for 5 hours, and then set S001 (STOP SW) of the outdoor main board from
the "STOP" side to "NORM" side. The engine will not start up while the switch is set to "STOP."
The indication on the seven-segment display changes from "      " to the normal display.
If the unit is operated while the valve is still closed,
the discharge pressure of the refrigerant will rise to
an abnormal level, and the compressor and the like
will be damaged.
