I. THE SYSTEM DOES NOT OPERATE

• The system does not restart immediately after the ON/

OFF button is pressed.

If the OPERATION lamp lights, the system is in normal con-
dition.
It does not restart immediately because a safety device oper-
ates to prevent overload of the system. After 3 minutes, the 
system will turn on again automatically.

• The system does not restart immediately when TEM-

PERATURE SETTING button is returned to the former 
position after pushing the button.

If the OPERATION lamp lights, the system is in normal con-
dition.
It does not restart immediately because a safety device oper-
ates to prevent overload of the system. After 3 minutes, the 
system will turn on again automatically.

• The system does not start when the display shows 

” (UNDER CENTRALIZED CONTROL) and it 

flashes for a few seconds after pressing an operation 
button.

temperature. The indoor unit switches to fan operation.

This is to prevent the cool air from being blown directly onto 
anyone in the room.
